Data Integrity proofs in cloud storage
This document discusses cloud computing and proposes a scheme for proof of data integrity in the cloud. It begins by defining cloud computing and describing the infrastructure needed to run applications over the internet. It then discusses security issues with cloud storage, where users do not have control over remotely stored data. The proposed scheme generates encrypted metadata for files and allows users to verify integrity by challenging the data center to provide specific bits, proving the file was not illegally modified. The scheme is best suited for encrypted static files stored in the cloud.
Security Problem With Cloud Computing
The document discusses security issues related to cloud computing data storage. It examines how companies can make informed decisions about storing data in the cloud and ensure sufficient privacy protection and regulatory compliance. The purpose is to look at basic security methods and how compliance is controlled. It recommends companies consider the security, availability, scalability, and stability of cloud providers before contracting with them. Privacy, security, and compliance are major concerns since companies lose direct oversight of their data and may not know where it is located or who the external providers are. Cloud computing storage may not be suitable for all businesses due to these challenges.

Abstract
Cloud computing provides a cost-effective solution for data storage by moving user data to large, remote data centers. However, this presents new security challenges as users no longer have control over the physical location of their data. The document proposes a scheme for users to verify the integrity of their data stored in the cloud. This proof of integrity could be agreed upon by cloud providers and users as part of the Service Level Agreement. The scheme allows users to check that their data in the cloud remains unchanged or has not been illegally modified or deleted.
Enabling Integrity for the Compressed Files in Cloud Server
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.

This document summarizes a research paper that proposes a system for privacy-preserving public auditing of cloud data storage. The system allows a third-party auditor (TPA) to verify the integrity of data stored with a cloud service provider on behalf of users, without learning anything about the actual data contents. The system uses a public key-based homomorphic linear authenticator technique that enables the TPA to perform audits without having access to the full data. This technique allows the TPA to efficiently audit multiple users' data simultaneously. The document describes the system components, methodology used involving key generation and auditing protocols, and concludes the proposed system provides security and performance guarantees for privacy-preserving public auditing of cloud data
Enhanced Data Partitioning Technique for Improving Cloud Data Storage Security
Cloud computing is a model for enabling for on demand network access to shared
configurable computing resources (e.g. networks, servers, storage, applications, and services).It is
based on virtualization and distributed computing technologies. Cloud Data storage systems enable
user to store data efficiently on server without any trouble of data resources. User can easily store
and retrieve their data remotely. The two biggest concerns about cloud data storage are reliability and
security. Clients aren’t like to entrust their data to another third party or companies without a
guarantee that they will be able to access therein formations whenever they want. In the existing
system, the data are stored in the cloud using dynamic data operation with computation which makes
the user need to make a copy for further updating and verification of the data loss. Different
distributed storing auditing techniques are used for overcoming the problem of data loss. Recent
work of this paper has show that data partitioning technique used for data storage by providing
Digital signature to every partitioning data and user .this technique allow user to upload or retrieve
the data with matching the digital signatures provided to them. This method ensures high cloud
storage integrity, enhanced error localization and easy identification of misbehaving server and
unauthorized access to the cloud server. Hence this work aims to store the data securely in reduced
space with less time and computational cost.
Dynamic Resource Allocation and Data Security for Cloud
Cloud computing is the next generation of IT organization. Cloud computing moves the software and
databases to the large centres where the management of services and data may not be fully trusted. In this system, we
focus on cloud data storage security, which has been an important aspect of quality of services. To ensure the
correctness of user’s data in the cloud, we propose an effective scheme with Advanced Encryption Standard and MD5
algorithm. Extensive security and performance analysis shows that the proposed scheme is highly efficient. In
proposed work we have developed efficient parallel data processing in clouds and present our research project for
parallel security. Parallel security is the data processing framework to explicitly exploit the dynamic storage along with
data security. We have proposed a strong, formal model for data security on cloud and corruption detection.

This document summarizes a research paper on improving user navigation through website structure using the CURE clustering algorithm. The paper proposes using CURE to group related website pages into clusters to minimize changes to the existing structure while enhancing navigation. Currently, k-means is often used but it does not account for website designers' lack of user understanding. CURE is evaluated on real website data and shown to provide navigation improvements with only minor link additions. The results indicate CURE is effective for clustering website pages in a way that guides users more efficiently.

A Secure, Scalable, Flexible and Fine-Grained Access Control Using Hierarchic...
Cloud Computing is going to be very popular technology in IT enterprises. For any enterprise the data stored is very huge
and invaluable. Since all tasks are performed through network it has become vital to have the secured use of legitimate data. In cloud
computing the most important matter of concern are data security and privacy along with flexibility, scalability and fine grained access
control of data being the other requirements to be maintained by cloud systems Access control is one of the prominent research topics
and hence various schemes have been proposed and implemented. But most of them do not provide flexibility, scalability and fine
grained access control of the data on the cloud. In order to address the issues of flexibility, scalability and fine grained access control
of remotely stored data on cloud we have proposed the hierarchical attribute set-based encryption (HASBE) which is the extension of
attribute- set-based encryption(ASBE) with a hierarchical structure of users. The proposed scheme achieves scalability by handling the
authority to appropriate entity in the hierarchical structure, inherits flexibility by allowing easy transfer and access to the data in case
of location switch. It provides fine grained access control of data by showing only the requested and authorized details to the user thus
improving the performance of the system. In addition, it provides efficient user revocation within expiration time, request to view
extra-attributes and privacy in the intra-level hierarchy is achieved. Thus the scheme is implemented to show that is efficient in access
control of data as well as security of data stored on cloud with comprehensive experiments

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.

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.
Distributed Scheme to Authenticate Data Storage Security in Cloud Computing
Distributed Scheme to Authenticate Data Storage Security in Cloud ComputingAIRCC Publishing Corporation
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.DISTRIBUTED SCHEME TO AUTHENTICATE DATA STORAGE SECURITY IN CLOUD COMPUTING

Cloud computing has been envisioned as the next-generation architecture of IT enterprise. 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 centers, where the management of the data and services may not be fully trustworthy. This unique attribute, however, poses many new security challenges which have not been well understood. In this article, we focus on cloud data storage security, which has always been an important aspect of quality of service. To ensure the correctness of users' data in the cloud, we propose an effective and flexible cryptography based scheme. Extensive security and performance analysis shows that the proposed scheme is highly efficient and resilient against malicious data modification attack.
Centralized Data Verification Scheme for Encrypted Cloud Data Services
Cloud environment supports data sharing between multiple users. Data integrity is violated
due to hardware / software failures and human errors. Data owners and public verifiers are involved to
efficiently audit cloud data integrity without retrieving the entire data from the cloud server. File and
block signatures are used in the integrity verification process.
“One Ring to RUle Them All” (Oruta) scheme is used for privacy-preserving public auditing process. In
oruta homomorphic authenticators are constructed using Ring Signatures. Ring signatures are used to
compute verification metadata needed to audit the correctness of shared data. The identity of the signer
on each block in shared data is kept private from public verifiers. Homomorphic authenticable ring
signature (HARS) scheme is applied to provide identity privacy with blockless verification. Batch
auditing mechanism supports to perform multiple auditing tasks simultaneously. Oruta is compatible
with random masking to preserve data privacy from public verifiers. Dynamic data management process
is handled with index hash tables. Traceability is not supported in oruta scheme. Data dynamism
sequence is not managed by the system. The system obtains high computational overhead
The proposed system is designed to perform public data verification with privacy. Traceability features
are provided with identity privacy. Group manager or data owner can be allowed to reveal the identity of
the signer based on verification metadata. Data version management mechanism is integrated with the
system.
IRJET- A Survey on Remote Data Possession Verification Protocol in Cloud Storage
This document summarizes a survey on remote data possession verification protocols for cloud storage. It begins with an abstract describing the problem of verifying integrity of outsourced data files on remote cloud servers. It then provides background on remote data possession verification (RDPV) protocols and discusses related work on ensuring data integrity and supporting dynamic operations. The document describes the system framework, RDPV protocol, use of homomorphic hash functions, and an optimized implementation using an operation record table to efficiently support dynamic operations like modifications. It concludes that the presented efficient and secure RDPV protocol is suitable for cloud storage applications.
Improve HLA based Encryption Process using fixed Size Aggregate Key generation
Cloud computing is an innovative idea for IT industries which provides several services to
users. In cloud computing secure authentication and data integrity of data is a major challenge, due to
internal and external threats. For improvement in data security over cloud, various techniques are
used.MAC based authentication is one of them, which suffers from undesirable systematic demerits
which have bounded usage and not secure verification, which may pose additional online load to users,
in a public auditing setting. Reliable and secure auditing are also challenging in cloud. In Cloud auditing
existing audit systems are based on aggregate key HLA algorithm. This algorithm is based on variable
sizes, different aggregate key generation, which encounters with security issues at decryption level.
Current Scheme generates a high length of key decryption that encounters with problem of space
complexity. To overcome these issues, We can improve HLA algorithm by improve aggregate key
generation, based on fixed key size. This algorithm generates constant aggregate key which will
overcomes problem of sharing of keys, security issues and space complexity.

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Ensuring data integrity on cloud data storage
- 2. Cloud storage moves the user’s data to large data centers, which are remotely located, on which user does not have any control. However, this unique feature of the cloud poses many new security challenges which need to be clearly understood and resolved. We provide a scheme which gives a proof of data integrity in the cloud which the customer can employ to check the correctness of his data in the cloud.
- 3. As data generation is far outpacing data storage it proves costly for small firms to frequently update their hardware whenever additional data is created. Also maintaining the storages can be a difficult task. It transmitting the file across the network to the client can consume heavy bandwidths. Cloud storage moves the user’s data to large data centers, which are remotely located. However, this uniquefeature of the cloud poses problems like data integrity, data security etc.
- 4. The main drawback of this scheme is the high resource costs it requires for the implementation. Also computing hash value for even a moderately large data files can be computationally burdensome for some clients (PDAs, mobile phones, etc). Data encryption is large so the disadvantage is small users with limited computational power (PDAs, mobile phones etc.).
- 5. We propose a remote data integrity checking protocol based on HLAs and RSA signature with the support public verifiability. It is important to note that our proof of data integrity protocol checks the integrity of data i.e. if the data has been illegally modified or deleted.
- 6. The support of public verifiability makes the protocol very flexible. User can deploy a TPA to check the data integrity. By reducing the costs of storage, maintenance and personnel. It reduces the chance of losing data by hardware failures. Not cheating the owner.
- 7. Cloud computing provides new economies for information technologies as well as new challenges. Properly constructed, it can be more secure than traditional IT infrastructure, but that construction requires the use of strong, integrated and usable security mechanisms. Thus our proposed system can be used for ensuring the integrity of data stored in cloud data storage devices. It will be an added advantage to all Cloud users.
