In the present scenario Cloud computing has turn out to be a vital mechanism in the field of computers. In this fast generation, cloud computing has swiftly extended as an substitute to conservative computing subsequently it can offer a flexible, dynamic, robust and cost effective structure. Data integrity is a significant measures in cloud storage. Storage outsourcing is a growing tendency which prompts a number of exciting security concerns, numerous of which have been widely inspected. Provable Data Possession (PDP) is the only the area that has recently seemed in the research literature. The chief concern is how frequently, efficiently as well as securely authenticate that a storage server is genuinely packing outsourced client’s data. The objective is to present a model for PDP that permits a client to store data on untrusted server to authenticate that the server holds the unique data without regaining it. The client reserves a constant quantity of metadata for the proof authentication. The challenge or response protocol connects a small amount of constant data, which reduces network communication. Accordingly, the PDP model for isolated data analysis supports prodigious data sets in extensively distributed storage systems.
Provable data possession for securing the data from untrusted serverIJERA Editor
The model described for the use of Provable data Possession which allow the client to access the stored data at
an Untrusted server that the server possesses the original data without retrieving it. This model executes the
probabilistic proof of possession by random set of blocks which is derived from the server that dramatically
reduces the cost of I/O. Sometimes the Client maintenance the constant amount of data which is used to verify
the proof. The response protocol can transmit a small amount of data, which can minimize network
communication. The two provably –Securer PDP Schemes presents more efficient schemes than previous

Efficient Implementation of Proof of Retrievability (OPOR) In Cloud Computing...IJERA Editor
Cloud computing has become an integral part of IT services, storing the application softwares and databases in
large centralized shared data servers. Since it’s a shared platform, the data and services may not be fully trust
worthy. In this work, we have implemented an efficient security model that ensures the data integrity of stored
data in cloud servers. The computational load of data verification linearly grows with the complexity of the
security model and this poses a serious problem at the resource constrained user’s end. Therefore to tackle this
problem we have implemented a new cloud storage scheme which ensures proof of retrivebility (OPoR) at a
third party cloud audit server to pre-process data before uploading into cloud storage server.

Improved Data Integrity Protection Regenerating-Coding Based Cloud StorageIJSRD
In today’s world a huge amount of data is loaded on the cloud storage. The protection of such type of data is main concern. It is somewhat difficult to protect such data against corruption, checking the integrity of data and also representation of failure data. Together with this it is also critical to implement fault tolerance among such type of data against corruptions. The private auditing for regenerating codes which is nothing but the existing system, developed to address such types of problems. The private auditing for regenerating codes can generate codes for such corrupted and incomplete data, but for this, data owners always have to stay online for checking completeness as well as integrity of data. In this paper, we are introducing the public auditing technique for regenerating code, based on cloud storage. The proxy is the main component in public auditing to regenerate failed authenticators in the absence of owner of the data. A public verifiable authenticator is also designed, which is generated by a several keys and can be regenerate using partial keys. We are also using pseudorandom function to preserve data privacy by randomizing the encode coefficient. Thus our technique can successfully regenerate the failed authenticators without data owner. Experiment implementation also indicates that our scheme is highly efficient and can be used to regenerate code in cloud based storage.
IRJET- Swift Retrieval of DNA Databases by Aggregating QueriesIRJET Journal
This document summarizes a research paper that proposes a new method for securely sharing and querying genomic DNA sequences stored in the cloud without violating privacy. The method builds on existing frameworks by offering deterministic results with zero error probability, and a scheme that is twice as fast but uses twice the storage space, which is preferable given cloud storage pricing. The encoding of the data supports a richer set of query types beyond exact matching, including counting matches, logical OR matches, handling ambiguities, threshold queries, and concealing results from the decrypting server. Linear and logistic regression algorithms are used to analyze the data. The literature review discusses previous work on securely sharing genomic data and transforming protocols to ensure accountability without compromising privacy.
Security Check in Cloud Computing through Third Party Auditorijsrd.com
In cloud computing, data owners crowd their data on cloud servers and users (data consumers) can access the data from cloud servers. Due to the data outsourcing, however, it requires an independent auditing service to check the data integrity in the cloud. Some existing remote integrity checking method scan only serve for static records data. Thus, cannot be used in the auditing service since the data in the cloud can be animatedly updated. Thus, an efficient and secure dynamic auditing protocol is required to convince data owners that the data are correctly stored in the cloud. In this paper, we first design an auditing framework for cloud storage systems for privacy-preserving auditing protocol. Then, we extend our auditing protocol to support the data dynamic operations, which is efficient to secure the random model.
This document presents a proposed approach called ICCC (Information Correctness to the Customers in Cloud Data Storage) to provide customers with proof of the correctness of their data stored in the cloud. The ICCC approach aims to minimize storage and computation costs for both customers and cloud storage providers. It involves the customer pre-processing their file by generating and encrypting metadata about random bits of each data block before uploading the file. This metadata is appended to the file. To verify correctness, the customer challenges the cloud storage provider by specifying a data block and bit, and the provider must return the correct metadata bit. This allows verification with minimal access to the entire file and low overhead for both parties.
Periodic Auditing of Data in Cloud Using Random BitsIJTET Journal
This document summarizes a research paper that proposes a scheme for periodically auditing data integrity in cloud storage using random bits. It introduces a proof of retrievability (POR) scheme to ensure data integrity based on service level agreements. The scheme uses probabilistic queries and periodic verification to improve the performance of audit services. It presents an architecture involving a client that pre-processes data before storing it, and a verification protocol to check integrity without retrieving the full data. The scheme aims to reduce overhead on clients and servers while minimizing proof sizes.
This document summarizes a research paper that proposes a framework called Cooperative Provable Data Possession (CPDP) to verify the integrity of data stored across multiple cloud storage providers. The framework uses two techniques: 1) a Hash Index Hierarchy that allows responses from different cloud providers to a client's challenge to be combined into a single response, and 2) Homomorphic Verifiable Responses that enable efficient verification of data stored on multiple cloud providers. The document outlines the security properties and performance benefits of the CPDP framework for verifying data integrity in a multi-cloud storage environment.

This document proposes and describes a new Map-Based Provable Multi-Copy Dynamic Data Possession (MB-PMDDP) scheme for cloud computing systems. The key points are:
1) It allows data owners to outsource and replicate dynamic/updateable data files across multiple cloud servers while provably ensuring the integrity and consistency of all file copies.
2) The verifier only needs to store and maintain a small amount of metadata (a map version table) to audit the integrity of all outsourced file copies, regardless of their number.
3) Authorized users can decrypt and access individual file copies obtained from the cloud servers using a single secret key shared with the data owner.
A Survey on A Secure Anti-Collusion Data Sharing Scheme for Dynamic Groups in...IRJET Journal
This document summarizes several papers related to secure data sharing schemes for dynamic groups in the cloud. It discusses key distribution methods using a key manager to distribute keys to group members. The document also reviews papers on revoking members from a group without compromising past signatures, verifying computations on outsourced data, variations of computational and decisional Diffie-Hellman problems, and proofs of retrievability for verifying intact files stored remotely. The conclusion is that mobile cloud computing can extend the boundaries of mobile applications but must satisfy security parameters like integrity, authorization and access control.
IRJET- A Novel Approach for Appreciable Group Data Allocation System with...IRJET Journal
This document proposes a novel approach for secure group data sharing and storage in cloud computing. It aims to enable anonymous data sharing within a group in the cloud with high security and efficiency. The approach uses group signatures and key agreement to allow group members to secretly share data about the group, while a common group key is determined based on key agreement to allow secure sharing and storage of group data in the cloud. Both theoretical and experimental analysis show that the proposed scheme is secure and efficient for group data sharing in cloud computing.

Survey on securing outsourced storages in cloudeSAT Journals
Abstract Cloud computing is one of the buzzwords of technological developments in the IT industry and service sectors. Widening the social capabilities of servicing for a user on the internet while narrowing the insufficiency to store information and provide facilities locally, computing interests are shifting towards cloud services. Cloud services although contributes to major advantages for servicing also incurs notification to major security issues. The issues and the approaches that can be taken to minimise or even eliminate their effects are discussed in this paper to progress toward more secure storage services on the cloud. Keywords: Cloud computing, Cloud Security, Outsourced Storages, Storage as a Service
IRJET-Auditing and Resisting Key Exposure on Cloud StorageIRJET Journal
1. The document discusses auditing and resisting key exposure in cloud storage. It proposes a new framework called an auditing protocol with key-exposure resilience that allows integrity of stored data to still be verified even if the client's current secret key is exposed.
2. It formalizes the definition and security model for such a protocol and proposes an efficient practical construction. The security proof and asymptotic performance analysis show the proposed protocol is secure and efficient.
3. Key techniques used include periodic key updates, homomorphic linear authenticators, and a novel authenticator construction to boost forward security and provide proof of retrievability with the current design.
Provable multicopy dynamic data possession in cloud computing systemsPvrtechnologies Nellore
The document proposes a scheme called MB-PMDDP that provides proof to customers that a cloud service provider (CSP) is storing multiple consistent copies of their dynamic data as agreed upon in their service contract. The scheme supports block-level updates to the outsourced data and allows authorized users to access the copies. It provides evidence that the CSP is not storing fewer copies than agreed and that all copies are consistent with the most recent data modifications. The scheme is analyzed and shown to be more efficient than extending existing single-copy dynamic data possession schemes to multiple copies. Experimental results on Amazon cloud validate the theoretical analysis. The scheme is also shown to be secure against colluding servers and a modification is discussed to identify corrupted copies.
Enabling Integrity for the Compressed Files in Cloud ServerIOSR Journals
This document proposes a scheme for enabling data integrity for compressed files stored in cloud servers. The scheme encrypts some bits of data from each data block using an RSA algorithm and polynomial hashing to generate hash values. These hash values are stored at the client and used to verify integrity by checking responses from the cloud server against the stored hashes. The scheme aims to minimize computational and storage overhead for clients by compressing files, encrypting only some data bits, and requiring clients to store just two secret functions rather than the full data. This allows integrity checks with low bandwidth consumption suitable for thin clients like mobile devices.

Improved Data Integrity Protection Regenerating-Coding Based Cloud StorageIJSRD
In today’s world a huge amount of data is loaded on the cloud storage. The protection of such type of data is main concern. It is somewhat difficult to protect such data against corruption, checking the integrity of data and also representation of failure data. Together with this it is also critical to implement fault tolerance among such type of data against corruptions. The private auditing for regenerating codes which is nothing but the existing system, developed to address such types of problems. The private auditing for regenerating codes can generate codes for such corrupted and incomplete data, but for this, data owners always have to stay online for checking completeness as well as integrity of data. In this paper, we are introducing the public auditing technique for regenerating code, based on cloud storage. The proxy is the main component in public auditing to regenerate failed authenticators in the absence of owner of the data. A public verifiable authenticator is also designed, which is generated by a several keys and can be regenerate using partial keys. We are also using pseudorandom function to preserve data privacy by randomizing the encode coefficient. Thus our technique can successfully regenerate the failed authenticators without data owner. Experiment implementation also indicates that our scheme is highly efficient and can be used to regenerate code in cloud based storage.
IRJET- Swift Retrieval of DNA Databases by Aggregating QueriesIRJET Journal
This document summarizes a research paper that proposes a new method for securely sharing and querying genomic DNA sequences stored in the cloud without violating privacy. The method builds on existing frameworks by offering deterministic results with zero error probability, and a scheme that is twice as fast but uses twice the storage space, which is preferable given cloud storage pricing. The encoding of the data supports a richer set of query types beyond exact matching, including counting matches, logical OR matches, handling ambiguities, threshold queries, and concealing results from the decrypting server. Linear and logistic regression algorithms are used to analyze the data. The literature review discusses previous work on securely sharing genomic data and transforming protocols to ensure accountability without compromising privacy.
Security Check in Cloud Computing through Third Party Auditorijsrd.com
In cloud computing, data owners crowd their data on cloud servers and users (data consumers) can access the data from cloud servers. Due to the data outsourcing, however, it requires an independent auditing service to check the data integrity in the cloud. Some existing remote integrity checking method scan only serve for static records data. Thus, cannot be used in the auditing service since the data in the cloud can be animatedly updated. Thus, an efficient and secure dynamic auditing protocol is required to convince data owners that the data are correctly stored in the cloud. In this paper, we first design an auditing framework for cloud storage systems for privacy-preserving auditing protocol. Then, we extend our auditing protocol to support the data dynamic operations, which is efficient to secure the random model.
This document presents a proposed approach called ICCC (Information Correctness to the Customers in Cloud Data Storage) to provide customers with proof of the correctness of their data stored in the cloud. The ICCC approach aims to minimize storage and computation costs for both customers and cloud storage providers. It involves the customer pre-processing their file by generating and encrypting metadata about random bits of each data block before uploading the file. This metadata is appended to the file. To verify correctness, the customer challenges the cloud storage provider by specifying a data block and bit, and the provider must return the correct metadata bit. This allows verification with minimal access to the entire file and low overhead for both parties.
Periodic Auditing of Data in Cloud Using Random BitsIJTET Journal
This document summarizes a research paper that proposes a scheme for periodically auditing data integrity in cloud storage using random bits. It introduces a proof of retrievability (POR) scheme to ensure data integrity based on service level agreements. The scheme uses probabilistic queries and periodic verification to improve the performance of audit services. It presents an architecture involving a client that pre-processes data before storing it, and a verification protocol to check integrity without retrieving the full data. The scheme aims to reduce overhead on clients and servers while minimizing proof sizes.
This document summarizes a research paper that proposes a framework called Cooperative Provable Data Possession (CPDP) to verify the integrity of data stored across multiple cloud storage providers. The framework uses two techniques: 1) a Hash Index Hierarchy that allows responses from different cloud providers to a client's challenge to be combined into a single response, and 2) Homomorphic Verifiable Responses that enable efficient verification of data stored on multiple cloud providers. The document outlines the security properties and performance benefits of the CPDP framework for verifying data integrity in a multi-cloud storage environment.

A Survey on Provable Multi-copy Dynamic Data Possession in Cloud Computing Sy...IRJET Journal
This document proposes and describes a new Map-Based Provable Multi-Copy Dynamic Data Possession (MB-PMDDP) scheme for cloud computing systems. The key points are:
1) It allows data owners to outsource and replicate dynamic/updateable data files across multiple cloud servers while provably ensuring the integrity and consistency of all file copies.
2) The verifier only needs to store and maintain a small amount of metadata (a map version table) to audit the integrity of all outsourced file copies, regardless of their number.
3) Authorized users can decrypt and access individual file copies obtained from the cloud servers using a single secret key shared with the data owner.
A Survey on A Secure Anti-Collusion Data Sharing Scheme for Dynamic Groups in...IRJET Journal
This document summarizes several papers related to secure data sharing schemes for dynamic groups in the cloud. It discusses key distribution methods using a key manager to distribute keys to group members. The document also reviews papers on revoking members from a group without compromising past signatures, verifying computations on outsourced data, variations of computational and decisional Diffie-Hellman problems, and proofs of retrievability for verifying intact files stored remotely. The conclusion is that mobile cloud computing can extend the boundaries of mobile applications but must satisfy security parameters like integrity, authorization and access control.
IRJET- A Novel Approach for Appreciable Group Data Allocation System with...IRJET Journal
This document proposes a novel approach for secure group data sharing and storage in cloud computing. It aims to enable anonymous data sharing within a group in the cloud with high security and efficiency. The approach uses group signatures and key agreement to allow group members to secretly share data about the group, while a common group key is determined based on key agreement to allow secure sharing and storage of group data in the cloud. Both theoretical and experimental analysis show that the proposed scheme is secure and efficient for group data sharing in cloud computing.

Cloud services although contributes to major advantages for servicing also incurs notification to major security issues. The issues and the approaches that can be taken to minimise or even eliminate their effects are discussed in this paper to progress toward more secure storage services on the cloud. Keywords: Cloud computing, Cloud Security, Outsourced Storages, Storage as a Service
IRJET-Auditing and Resisting Key Exposure on Cloud StorageIRJET Journal
1. The document discusses auditing and resisting key exposure in cloud storage. It proposes a new framework called an auditing protocol with key-exposure resilience that allows integrity of stored data to still be verified even if the client's current secret key is exposed.
2. It formalizes the definition and security model for such a protocol and proposes an efficient practical construction. The security proof and asymptotic performance analysis show the proposed protocol is secure and efficient.
3. Key techniques used include periodic key updates, homomorphic linear authenticators, and a novel authenticator construction to boost forward security and provide proof of retrievability with the current design.
Provable multicopy dynamic data possession in cloud computing systemsPvrtechnologies Nellore
The document proposes a scheme called MB-PMDDP that provides proof to customers that a cloud service provider (CSP) is storing multiple consistent copies of their dynamic data as agreed upon in their service contract. The scheme supports block-level updates to the outsourced data and allows authorized users to access the copies. It provides evidence that the CSP is not storing fewer copies than agreed and that all copies are consistent with the most recent data modifications. The scheme is analyzed and shown to be more efficient than extending existing single-copy dynamic data possession schemes to multiple copies. Experimental results on Amazon cloud validate the theoretical analysis. The scheme is also shown to be secure against colluding servers and a modification is discussed to identify corrupted copies.
Enabling Integrity for the Compressed Files in Cloud ServerIOSR Journals
This document proposes a scheme for enabling data integrity for compressed files stored in cloud servers. The scheme encrypts some bits of data from each data block using an RSA algorithm and polynomial hashing to generate hash values. These hash values are stored at the client and used to verify integrity by checking responses from the cloud server against the stored hashes. The scheme aims to minimize computational and storage overhead for clients by compressing files, encrypting only some data bits, and requiring clients to store just two secret functions rather than the full data. This allows integrity checks with low bandwidth consumption suitable for thin clients like mobile devices.

International Journal of Computational Engineering Research(IJCER) is an intentional online Journal in English monthly publishing journal. This Journal publish original research work that contributes significantly to further the scientific knowledge in engineering and Technology.
This document presents a Cooperative Provable Data Possession (CPDP) scheme to ensure data integrity in a multicloud storage system. The CPDP scheme uses a trusted third party to generate secret keys, verification tags for data blocks, and store public parameters. It allows a client to issue challenges to verify the integrity of its data stored across multiple cloud service providers. The verification process involves the cloud providers proving possession of the original data file without retrieving the whole file. This scheme aims to efficiently verify data integrity in a multicloud system with support for data migration and scalability.
Cloud storage permits users to store their data in a remote server to eliminate overpriced local storage and
management costs, then access data anytime, anyplace. Variety of solutions are projected to tackle the integrity of
stored cloud data and its retrievability. One amongst the most important consideration with data storage in cloud
today is data integrity verification of untrusted cloud. A very important approach to attain this goal of data integrity
verification is Proof Of Retrievability, in which the storage server will assure verifier via a concise proof that a
client’s file is obtainable. In this work, the study on static and dynamic approaches of Proof Of Retrievability and
numerous techniques are discussed.
The document proposes a system called ICCC (Information Correctness to Customers in Cloud Data Storage) that provides a proof of correctness to customers storing data in the cloud. This ensures the cloud storage provider has not modified the customer's data without approval. The system aims to verify correctness with minimal storage/computation at the client and cloud server sides and low bandwidth usage. It allows verification using only a small portion of the stored data file, independent of the file size. The ICCC proof could be included in service level agreements to assure customers of their data's integrity in the cloud.
Protecting Global Records Sharing with Identity Based Access Control ListEditor IJCATR
This document summarizes a research paper on TrustedDB, an outsourced database prototype that allows clients to execute SQL queries on encrypted data with privacy and regulatory compliance. It does this by leveraging tamper-proof cryptographic coprocessors located on the server, removing limitations on query types. The system focuses on providing a secure data sharing service while allowing dynamic access. Performance and costs are evaluated by implementing and running TrustedDB on hardware security modules.
A Study of A Method To Provide Minimized Bandwidth Consumption Using Regenera...IJERA Editor
Cloud storage systems to protect data from corruptions, redundant data to tolerate failures of storage and lost data should be repaired when storage fails. Regenerating codes provide fault tolerance by striping data across multiple servers, while using less repair traffic than traditional erasure codes during failure recovery. In previous research implemented practical Data Integrity Protection (DIP) scheme for regenerating-coding based cloud storage. Functional Minimum-Storage Regenerating (FMSR) codes and it construct FMSR-DIP codes, which allow clients to remotely verify the integrity of random subsets of long-term archival data under a multi server setting. The problem is to optimize bandwidth consumption when repairing multiple failures. The cooperative repair of multiple failures can help to further save bandwidth consumption when multiple failures are being repaired.
A Survey on Different Techniques Used in Decentralized Cloud ComputingEditor IJCATR
This paper proposes various methods for anonymous authentication for data stored in cloud. Cloud verifies the authenticity
of the series without knowing the user’s identity before storing data. This paper also has the added feature of access control in which
only valid users are able to decrypt the stored information. These schemes also prevents replay attacks and supports creation,
modification, and reading data stored in the cloud. Moreover, our authentication and access control scheme is decentralized and robust,
unlike other access control schemes designed for clouds which are centralized. The communication, computation, and storage
overheads are comparable to centralized approaches .The aim of this paper is to cover many security issues arises in cloud computing
and different schemes to prevent security risks in cloud. Storage-as-a-service (Saas) offered by cloud service providers (CSPs) is a paid
facility that enables organizations to outsource their sensitive data to be stored on remote servers. In this paper, we propose a cloudbased
storage schemes that allows the data owner to benefit from the facilities offered by the CSP and enables indirect mutual trust
between them. This Paper provides different authentication techniques and algorithms for cloud security.

Deduplication on Encrypted Big Data in HDFSIRJET Journal
This document discusses data deduplication techniques for big data stored in HDFS (Hadoop Distributed File System). It begins by defining data deduplication as a data compression technique that eliminates duplicate copies of repeating data to reduce storage space. The document then reviews different levels and types of deduplication (file-level, block-level, inline, post-process, client-side, target-based) and discusses how deduplication can reduce storage needs significantly for backup applications and file systems. However, security and privacy concerns arise when sensitive user data is deduplicated in the cloud. The document proposes a new authorized deduplication scheme that considers access control policies of users in addition to the data itself.
Cloud Computing is the revolution in current generation IT enterprise. Cloud computing displaces database and application software to the large data centres, where the management of services and data may not be predictable, where as the conventional solutions, for IT services are under proper logical, physical and personal controls. This aspect attribute, however comprises different security challenges which have not been well understood. It concentrates on cloud data storage security which has always been an important aspect of quality of service (QOS). In this paper, we designed and simulated an adaptable and efficient scheme to guarantee the correctness of user data stored in the cloud and also with some prominent features. Homomorphic token is used for distributed verification of erasure – coded data. By using this scheme, we can identify misbehaving servers. In spite of past works, our scheme supports effective and secure dynamic operations on data blocks such as data insertion, deletion and modification. In contrast to traditional solutions, where the IT services are under proper physical, logical and personnel controls, cloud computing moves the application software and databases to the large data centres, where the data management and services may not be absolutely truthful. This effective security and performance analysis describes that the proposed scheme is extremely flexible against malicious data modification, convoluted failures and server clouding attacks.

Image Binarization for the uses of Preprocessing to Detect Brain Abnormality ...Journal For Research
Computerized MR of brain image binarization for the uses of preprocessing of features extraction and brain abnormality identification of brain has been described. Binarization is used as intermediate steps of many MR of brain normal and abnormal tissues detection. One of the main problems of MRI binarization is that many pixels of brain part cannot be correctly binarized due to the extensive black background or the large variation in contrast between background and foreground of MRI. Proposed binarization determines a threshold value using mean, variance, standard deviation and entropy followed by a non-gamut enhancement that can overcome the binarization problem. The proposed binarization technique is extensively tested with a variety of MRI and generates good binarization with improved accuracy and reduced error.
A Research Paper on BFO and PSO Based Movie Recommendation System | J4RV4I1016Journal For Research
The objective of this work is to assess the utility of personalized recommendation system (PRS) in the field of movie recommendation using a new model based on neural network classification and hybrid optimization algorithm. We have used advantages of both the evolutionary optimization algorithms which are Particle swarm optimization (PSO) and Bacteria foraging optimization (BFO). In its implementation a NN classification model is used to obtain a movie recommendation which predict ratings of movie. Parameters or attributes on which movie ratings are dependent are supplied by user's demographic details and movie content information. The efficiency and accuracy of proposed method is verified by multiple experiments based on the Movie Lens benchmark dataset. Hybrid optimization algorithm selects best attributes from total supplied attributes of recommendation system and gives more accurate rating with less time taken. In present scenario movie database is becoming larger so we need an optimized recommendation system for better performance in terms of time and accuracy.
IoT based Digital Agriculture Monitoring System and Their Impact on Optimal U...Journal For Research
Although precision agriculture has been adopted in few countries, the greenhouse based modern agriculture industry in India still needs to be modernized with the involvement of technology for better production and cost control. In this paper we proposed a multifunction model for smart agriculture based on IoT. Due to variable atmospheric circumstances these conditions sometimes may vary from place to place in large farmhouse, which makes very difficult to maintain the uniform condition at all the places in the farmhouse manually. Soil and environment properties are sensed and periodically sent to cloud network through IoT. Analysis on cloud data is done for water requirement, total production and maintaining uniform environment conditions throughout greenhouse farm. Proposed model is beneficial for increase in agricultural production and for cost control and real time monitoring of farm.

HCI BASED APPLICATION FOR PLAYING COMPUTER GAMES | J4RV4I1014Journal For Research
This paper describes a command interface for games based on hand gestures and voice command defined by postures, movement and location. The system uses computer vision requiring no sensors or markers by the user. In voice command the speech recognizer, recognize the input from the user. It stores and passes command to the game, action takes place. We propose a simple architecture for performing real time colour detection and motion tracking using a webcam. The next step is to track the motion of the specified colours and the resulting actions are given as input commands to the system. We specify blue colour for motion tracking and green colour for mouse pointer. The speech recognition is the process of automatically recognizing a certain word spoken by a particular speaker based on individual information included in speech waves. This application will help in reduction in hardware requirement and can be implemented in other electronic devices also.
A REVIEW ON DESIGN OF PUBLIC TRANSPORTATION SYSTEM IN CHANDRAPUR CITY | J4RV4...Journal For Research
As we know the population of Chandrapur City has increased so far in this years and with that has increased the vehicles causing high traffic volume & rise in pollution. But the transportation system in Chandrapur City is still the same. To reduce the traffic volume & pollution, we have to study & design the new transportation system in Chandrapur City. The system would be as similar to Nagpur City with the implementation of Star City Buses. In this Study we would first compare the speed of various vehicles. Collection of population details of Chandrapur City, approximate number of vehicles running on road, collection of data with respect to Ticket fares in Nagpur City- whether it is according to Kilometers or places to be reached, calculation of Ticket Fares for Chandrapur City on the basis data collected. By all these, the best mode of transport in City can be studied. On the basis of above data collected from various respected fields, we will then proceed for the Design part of urban transport system in Chandrapur City. For Design purpose, firstly we have to mark the centre of the City, when the centre is decided; we will then select the Bus Terminus. From centre of the city, we would prefer to select the routes of the Buses. One route will be for the city side like Jatpura Gate, Pathanpura Gate. One route will be for Ballarpur going road. The other one for Mul going road, then next for Nagpur road. We could decide as many routes once we get the clear idea about all data. By getting all this details, the next step is to design the destination points of Buses. Then we have to design about the Bus bays, to reduce congestion in the particular intersections or Stops of bus. After the design also can suggest for Bus lanes. Implementation of Bus Rapid Transit System (BRT system) is the main aim behind to develop transportation mode of City. The design of the Transport System can be designed with the help of various software’s like AutoCAD and Revit.

LABORATORY STUDY OF STRONG, MODERATE AND WEAK SANDSTONES | J4RV4I1012Journal For Research
Sandstones from seven different hydroelectric projects have been assessed to compare their water-related properties and engineering parameters and the comprehensive analysis has been presented. The study has been done by categorizing the sandstones in to three categories i.e. weak, moderate & strong sandstones. The study leads to four broad inferences: (1), there could be very large variation between two sandstones; e.g., here, sandstone S2, S4 & S5, vis-à-vis other two strong sandstones, is superior in all respects. (2), the four weak sandstones differ in respect of some – not all – properties and parameters. (3), none of the four weak sandstones is better than the other two in respect of all properties and parameters. (4), moderate sandstone shows higher values of shear strength parameters in comparison to all the sandstones (including stronger sandstones also) except S3 strong sandstone. In respect of individual properties, the grain density of all sandstones is similar, though their bulk densities, apparent porosity and water content show great variation. The weak, moderate and strong sandstones show qualitative difference in their uniaxial compressive strength and wave velocity (compression and shear, both); and the two are directly proportional. The study clearly demonstrates that there is no one-to-one correspondence between any two properties and parameters, but there is a diffused and/ or qualitative relationship between different sandstones, or certain properties and parameters of a particular variant.
DESIGN ANALYSIS AND FABRICATION OF MANUAL RICE TRANSPLANTING MACHINE | J4RV4I...Journal For Research
Need of rice transplanting machine is growing nowadays because of unique feature seeding in well sequence and well manners. This will save too much efforts of human being. Class of people who uses this kind of machine is farmers and they are having poor economic background. To feed growing population is a huge challenge. Importation of rice will lead to drain out the economy of the country. Mechanization of paddy sector will lead to higher productivity with releasing of work force to other sectors. The objective of this project is to design a paddy transplanting mechanism to transplant paddy seedling by small scale farmers in the country. Hence, this is considered as an activity that needed mechanization. For mechanization the modeling and simulation evaluated for hand operated rice seeding machine, which is help the farmers to planting more and more amount of rice in good quality with low energy consumption and less harm to the environment. India is predominately an agricultural country with rice as one of its main food crop. It Produce about 80 million tons rice annually which is about 22% of the world rice production. Culturally transplanting of young seeding is preferred over direct seeding for better yield and better crop management practice. But this operation requires large amount of manpower (about 400 Man-Hour/ha) and task is very laborious involving working in stopping posture and moving in muddy field.

AN INTEGRATED APPROACH TO REDUCE INTRA CITY TRAFFIC AT COIMBATORE | J4RV4I1002Journal For Research
Coimbatore (11.0168°N,76.9558°E) is a fast developing cosmopolitan city with large number of industries and educational institutions. The development has lead to a large number of vehicles causing heavy traffic. The traffic congestion at Coimbatore has been a major problem which causes traffic jams and accidents. The major reason for traffic has been the mofussil buses that operate in the city. Around 1300 mofussil buses enter into the city, these buses play an important role in traffic congestion. The best solution is to construct a centralized bus stand at the outskirts of the city. This would reduce the traffic, accidents and also leads to development of the outskirts of the city. A suitable location near the city with sufficient road access to connecting cities has been chosen and the bus terminus has been designed, modeled with all facilities and features.
A REVIEW STUDY ON GAS-SOLID CYCLONE SEPARATOR USING LAPPLE MODEL | J4RV4I1001Journal For Research
Cyclone is the most commonly used device to separate dust particles from gas and dust flow. The performance of cyclone separator can be measured in terms of collection efficiency and pressure drop. Parameters like Inlet Flow velocity, the particle size distribution in feed, dimensions of inlet and outlet ducts and cyclone affects the performance of cyclone significantly. Various Mathematical models used for calculation of cut off diameter of separator, flow rate, target efficiency and no. of vortex inside the cyclone to design and study to check the performance of existing cyclone separator. Also new dimensions can be design with help of models. Here, in this study the efficiency achieved with Lapple model cumulatively 86.47%.
During past few years, brain tumor segmentation in CT has become an emergent research area in the field of medical imaging system. Brain tumor detection helps in finding the exact size and location of tumor. An efficient algorithm is proposed in this project for tumor detection based on segmentation and morphological operators. Firstly quality of scanned image is enhanced and then morphological operators are applied to detect the tumor in the scanned image. The problem with biopsy is that the patient has to be hospitalized and also the results (around 15%) give false negative. Scan images are read by radiologist but it's a subjective analysis which requires more experience. In the proposed work we segment the renal region and then classify the tumors as benign or malignant by using ANFIS, which is a non-invasive automated process. This approach reduces the waiting time of the patient.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

Abstract
In the present scenario Cloud computing has turn out to be a vital mechanism in the field of computers. In this fast generation,
cloud computing has swiftly extended as an substitute to conservative computing subsequently it can offer a flexible, dynamic,
robust and cost effective structure. Data integrity is a significant measures in cloud storage. Storage outsourcing is a growing
tendency which prompts a number of exciting security concerns, numerous of which have been widely inspected. Provable Data
Possession (PDP) is the only the area that has recently seemed in the research literature. The chief concern is how frequently,
efficiently as well as securely authenticate that a storage server is genuinely packing outsourced client’s data. The objective is to
present a model for PDP that permits a client to store data on untrusted server to authenticate that the server holds the unique data
without regaining it. The client reserves a constant quantity of metadata for the proof authentication. The challenge or response
protocol connects a small amount of constant data, which reduces network communication. Accordingly, the PDP model for
isolated data analysis supports prodigious data sets in extensively distributed storage systems.

_______________________________________________________________________________________________________
I. INTRODUCTION
When several interior and/or exterior cloud services are combined, we can acquire a distributed cloud environment, i.e., multi
cloud. Multi cloud is the augmentation of hybrid cloud. Whenever multi clouds are used for client data storing, for the client data
management distributed cloud storage platforms are very crucial. Of course, multi cloud storage platform is also more susceptible
to security attacks. The storage server are expected to be untrusted with respect to security as well as reliability. So the problem is
strengthened by the client presence on a trivial computing device with partial resources. To inspect the availability and integrity of
subcontracted data on cloud storages, scholars have projected two elementary approaches called PDP and POR.
Ateniese et al. first projected the PDP model for guaranteeing control of files on untrusted storages as well as provided RSA-
based structure for a stationary case that attains the communication cost. They also projected an openly verifiable version, which
not only permits owner but also everyone, to encounter the data possession of the server. This characteristic considerably extended
application regions of PDP protocol because of segregation of data owners as well as the users. Though, these structures are
insecure in contradiction of replay attacks in dynamic scenarios due to the reliance on the pointer of the blocks. Besides, they are
not suitable for multi-cloud storage due to property of homomorphism loss with respect to verification process. In sequence to
support operations on dynamic data, Ateniese et al. established a dynamic PDP resolution which is called as Scalable PDP. This
lead to a lightweight PDP structure built on cryptographic hash function as well as symmetric key encryption, in turn servers can
betray the owners by means of earlier metadata or replies due to the absence of randomness in the tests. Updates and tests are
restricted and fixed in advance as well as users cannot accomplish block insertions anywhere.
In the current years, the perception of intermediary warehousing as well as outsourcing of data has become fairly widespread.
Outsourcing of data fundamentally means that the data owner transfers data to the intermediary provider (server) which is
hypothetical to, apparently for a fee and faithfully accumulate the data as well as make it accessible to the owner and possibly to

others on demand. Interesting features of outsourcing comprise minimized costs from storage investments, maintenance &
personnel as well as augmented availability and clear up-keep of data. There are numerous security-related research concerns in
data outsourcing have been considered previously. Primary work focused on data authentication and integrity which mainly focus
on how efficiently as well as securely guarantee that server yields precise and comprehensive outcomes in reply to its client
inquiries.
Fig. 1: PDP
The Application of Provable Data Possession (PDP) occasionally as Proof of Data Retrievability (POR) that cracked up in the
research literature. The dominant goal of PDP is to permit client to efficiently, regularly and securely authenticate that a server
that stores possibly very large quantity of client data such that server that does not dishonest the client. In this context, dishonest
means that the server might erase certain data or might not store data completely in fast storage. It is vital to check storage server
may not be malicious in place, it might be modestly untrustworthy and lose or inadvertently unethical hosted data. A useful PDP
technique must be applicable to malicious and unreliable servers. The issue is further complex by the situation that the consumer
will operate a trivial device (e.g., a PDA or a cell-phone) with restricted CPU, battery power and communication amenities. Hence,
the necessity to reduce bandwidth and local computation overhead in performing each verification by the client.
Fig. 2: PDP
The latest results of PDP as well as POR has emphasized the prominence of the problem and recommended two dissimilar
approaches. Foremost approach is related to public key based method permitting any verifier apart from client to inquiry the server
and attain an interactive proof of data possession which is referred as public verifiability. The collaboration can be recurrent any
amount of times, each time ensuing in a new proof. The POR scheme uses distinct blocks called sentinels that are hidden amongst
other data blocks. Throughout the verification phase, the client requests for arbitrarily chosen sentinels and verifies whether they
are complete. In case if the server modifies or removes portion of the data, then sentinels will also be aff ected for certain probability.
Nevertheless, sentinels need to be indistinguishable when compared to other regular blocks; this suggests that blocks need to be
encrypted. Thus, similar to PDP scheme which is not conceivable to custom POR for public databases like libraries, repositories
or archives. In supplementary arguments, POR is used in limited confidential data. In addition, inquiries are also limited and fixed
a priori due to sentinels with their position inside the database need to be revealed to the server for each query and a exposed
sentinel cannot be reclaimed
II. SCOPE
Generally data integrity of Remote servers are authenticated based on PDP technique. In a classical PDP model, the data owner
produces certain metadata/information to be used for future authentication purposes for a data file over a challenge response
protocol through the remote/cloud server. Basically data owner directs the data file onto remote server for storage which in turn
seems to be untrusted and erases the native file copy. But the data server still process native form of data file as a proof. It
appropriately calculates a acknowledgement to a challenge vector directed from a verifier who in turn can be the innovative data
owner or additional trusted individual that allowance certain information with the data owner. Investigators have suggested
dissimilar deviations of PDP schemes under diverse cryptographic assumptions, one of the fundamental design principles of data
outsourcing is to deliver dynamic data scalability for numerous applications. This shows that the stored data remotely not only
retrieved by the authorized users, and also data owner can reorganized data and scaling of data is possible. Dynamic PDP building

reported in the literature emphasis on the provable control of a distinct dynamic data file copy. Although PDP schemes have been
accessible for numerous static data copies, PDP scheme survives for multiple dynamic data copies. PDP is a constraint arrangement
of memory, memory scrutiny validates each read and write that program produced at any granularity. Because of this constraint,
memory inspection is considerably tough and exclusive rather than verifying data possession.
In Association to PDP, Naor and Rothblum presented sub-linear authentication problem, authenticating that the file stored on
remote server has not been suggestively corrupted. They demonstrated that the actuality of one-way functions is a vital constraint
for effective online scrutiny.Alike to PDP, Juels and Kaliski presented the concept of Proof Of Retrievability(POR), which permits
a server to induce the client to retrieve a file that was stored previously on server. The key POR scheme employs concealed blocks
hidden amongst consistent file blocks in order to perceive modification of data by the server. Even though analogous in scope with
PDP, POR scheme can only be utilized to encrypted files and also to handle restricted number of queries, which need to be stable
prior. A substitute for scrutinizing remote storage is to create data resistant to untraceable deletion through tangle, which encodes
data to generate dependencies among unrelated data through the storage system. Thus, any sort of data deletion reveals and removes
other unrelated data through the system.
A predominantly compulsive PDP application is distributed data storage systems. If examined Freenet network or the internet
Cooperative Backup Scheme .These systems depends on and also succeed on free storage. One purpose for misbehavior in these
systems are due to the storage space which involves real budgetary price. Furthermore, in a distributed backup system, a consumer
who allows utilization of some space to other consumers’ backup data is usually approved usage of a relative quantity of space for
backup anywhere else in the network. Henceforth, a customer need to obtain better redundancy for the data. Furthermore, customers
will abode trust on such system as long as the consistent storage relied, which is tough in case of massive cheating.
A PDP structure could perform as a influential deterrent for cheating, thus cumulative trust in the system as well as serving its
popularity and usage. To conclude, similar reflections can be appeal to alternate service models like peer-to-peer data archiving,
where novel practices of assurance related to data integrity as well as data accessibility are required.
III. PROPOSED MODEL
IDPDP protocol is mainly projected to collect data on multi cloud. This protocol removes the required certificate management.
Basically in this type f system depending on the size as well as type of customer’s data, data will be scattered on multi cloud server.
The private key for the customer will be generated by private key generator in this scenario which comprises customer’s distinct
identification. Initially Customer’s data is transported to combiner later combiner allocates the data depending on the size as well
as data type. Verifier directs the provocation to the combiner in turn the combiner transmits the provocation to the respective cloud.
Subsequently combiner groups the outcome and verifies if valid or not. In case if it is valid then permits client to store the data on
multi cloud. At this stage Extract, PKG generates private key for the client. Then the client generates the block-tag pair as well as
uploads data to combiner. The combiner allocates the block-tag sets to the diverse cloud servers created on the storage metadata.
The verifier directs the challenge to combiner then the combiner allocates challenge query to the relative cloud servers created on
metadata of storage. The cloud servers respond for the challenge such that the combiner combines all the cloud server responses.
Then the combiner guides the joint response to the verifier. Lastly, the verifier approves whether the combined response is valid
or not. The concrete ID-DPDP construction largely originates from the signature, PDP as well as distributed computing. Then the
signature interconnects the identity depending on private key of the customer. Distributed computing is adapted for storing the
client data on multi-cloud servers. Simultaneously distributed computing also combines the multi-cloud servers’ replies to respond
for the verifier challenge. ID-DPDP protocol is erected based on the PDP protocol adopting signature as well as distributed
computing.

includes four diverse objects that comprises Client, Cloud Server, Combiner and Private Key Generator.

Client stores a huge data on multi-cloud for maintenance as well as for computation. This data can be from distinct consumer
or from business organization.
CS (Cloud Server) is basically managed by service provider of cloud, which has substantial storage space along with
computation resource for the maintenance of the clients’ data.
Combiner takes the storage demand and allocates the block-tag sets to the matching cloud servers. While getting the challenge,
it separates the challenge such that the challenges will be dispersed to diverse cloud servers. Though accommodating the
replies and transmits combined replies to the verifier from the cloud servers.
PKG (Private Key Generator) receives the identity, it outputs the analogous private key.
Fig. 4: PKG
As per expected popularity of clouds, in recently years many tools as well as technologies for hybrid clouds are evolving like
platform VM Orchestrator, VMware vSphere. They indeed assist consumers to build comparably scalable lower cost, site
autonomous platform for handling clients' data. Still, in case of significant platform is susceptible to security attacks might be the
source for irretrievable damage to the client’s data like the trustworthy data in an organization may be unlawfully retrieved by
means of remote interfaces, or the related data and documentations are lost or damaged when the stored data in an unspecified
storage cluster external to the enterprise. So, for every service provider it is vital to offer protected management practices to
guarantee their storage services. There exist numerous tools with technologies relevant to multi cloud. These tools assist cloud
providers to build an appropriate distributed cloud storage platform for client data surety as well as management.

IV. RELATED WORK
RDPC (Remote Data Possession Checking) permits the client who have stored data on public cloud server (PCS) can authenticate
whether the server holds the unique data without reclaiming it. The model yields probabilistic proofs of ownership by sampling
arbitrary sets of chunks from the server, which radically decreases I/O costs. The client preserves a continuous quantity of metadata
to authenticate the proof. The challenge/response protocol communicates a trivial, continuous quantity of data, which reduces
network communication. In sequence to attain protected RDPC implementations, Ateniese et al. projected a PDP model and
considered two provably-secure PDP structures centered on the effort of huge integer factoring. They advanced the original model
and projected a dynamic PDP structure but their suggestions does not ensure the enclosure of operation. In sequence to resolve this
difficult, Erway et al. projected a full-dynamic PDP structure by engaging an authentic flip table. Subsequently Ateniese et al.’s
revolutionary work, researchers devout countless efforts to RDPC with protracted models and novel protocols. Retrievability’s
(POR) major dissimilarities is the proof , POR in which a storage data server cannot only verify the verifier that actually stores
entire data of a client, even it can demonstrate that the consumers can retrieve the entire data at any time. This is durable than the
consistent PDP notion. Shacham offered the initial POR structure with provable security. The challenge is to create POR schemes
efficient and secure. The core advantage of cloud storage is to permit worldwide data access with self-governing geographical
sites. This suggests that the end devices might be moveable and partial in computation and with storage. Consistent RDPC protocols
are more appropriate for cloud consumers prepared with mobile end devices.

V. CONCLUSION
This paper mainly focus towards demonstration for the building of collective reliability authentication mechanism for disseminated
data outsourcing in hybrid clouds. We have verified the difficulties involved in auditing, in case if the data of user stored on
untrusted server. We also presented a prototypical model for PDP, this model is required to reduce the file block accesses, the
server calculation, and communication between server and client. Vital components of our systems are provision for spot scrutiny,
which need to ensure the system remain lightweight along with the homomorphic verifiable tags which in turn permits to
authenticate data possession without actual data file access. Our method mainly presents a trivial quantity of calculation and
communication overheads. Consequently, the solution can be preserved as a novel candidate for data reliability authentication for
outsourcing data storage schemes. As per the forthcoming work, we wanted to cover and explore extra effective CPDP structures.
Lastly, this wok shows that now also it is challenging task for the tag generation along with length irrelevant to the data blocks
size. Possibility to explore an issue to deliver the provision for variable size block authentication.
VI. FUTURE WORK
We wanted to cover and explore extra effective CPDP structures. Lastly, this wok shows that now also it is challenging task for
the tag generation along with length irrelevant to the data blocks size. Possibility to explore an issue to deliver the provision for
variable size block authentication. This paper validates the ID-DPDP scheme and security in multi-cloud. We want to suggest the
first ID-DPDP protocol is protected underneath the hypothesis that the CDH task is hard. Also the removal of certificate
management this protocol has flexibility and effectiveness. And also proposed to realize private verification, surrogate verification
along with public verification on the client’s data using ID-DPDP protocol
