Role Based Access Control Model (RBACM) With Efficient Genetic Algorithm (GA)...dbpublications
Cloud computing is one the promising and emerging field in Information Technology because of its performance, low cost and great availability. Cloud computing basically gives services to an individual and the organization through the network with the capability to scale down or up their different kinds of services. The basic service of cloud computing system is known as a cloud storage system which containing a collection of storage servers. These storage servers gives long-term storage services by using the internet with free of cost. However, the storing data using cloud system of third party causes very serious problem over data confidentiality. Typically, different kinds of encryption schemes are used to protect the cloud data confidentiality, but it take more time to process even a single operation. Thus, in this paper proposes cloud data confidentiality by integrates encoding, encrypting and forwarding. Token Based Data Security Algorithm (TBDSA) along with RSA and AES is used for decryption and encryption process and Role Based Access Control Model (RBACM) is access at the time of data forwarding. Here, cloud user’s accessing password is created by using encoding process which is done by Genetic Algorithm (GA) and process of GA is presented in this paper. This
TBDSA and GA algorithms takes minimum time to execute and raises the system performance.
An Improved Integrated Hash and Attributed based Encryption Model on High Dim...IJECEIAES
Cloud computing is a distributed architecture where user can store their private, public or any application software components on it. Many cloud based privacy protection solutions have been implemented, however most of them only focus on limited data resources and storage format. Data confidentiality and inefficient data access methods are the major issues which block the cloud users to store their high dimensional data. With more and more cloud based applications are being available and stored on various cloud servers, a novel multi-user based privacy protection mechanism need to design and develop to improve the privacy protection on high dimensional data. In this paper, a novel integrity algorithm with attribute based encryption model was implemented to ensure confidentiality for high dimensional data security on cloud storage. The main objective of this model is to store, transmit and retrieve the high dimensional cloud data with low computational time and high security. Experimental results show that the proposed model has high data scalability, less computational time and low memory usage compared to traditional cloud based privacy protection models.

Survey on Privacy- Preserving Multi keyword Ranked Search over Encrypted Clou...Editor IJMTER
The advent of cloud computing, data owners are motivated to outsource their complex
data management systems from local sites to commercial public cloud for great flexibility and
economic savings. But for protecting data privacy, sensitive data has to be encrypted before
outsourcing.Considering the large number of data users and documents in cloud, it is crucial for
the search service to allow multi-keyword query and provide result similarity ranking to meet the
effective data retrieval need. Related works on searchable encryption focus on single keyword
search or Boolean keyword search, and rarely differentiate the search results. We first propose a
basic MRSE scheme using secure inner product computation, and then significantly improve it to
meet different privacy requirements in two levels of threat models. The Incremental High Utility
Pattern Transaction Frequency Tree (IHUPTF-Tree) is designed according to the transaction
frequency (descending order) of items to obtain a compact tree.
By using high utility pattern the items can be arranged in an efficient manner. Tree structure
is used to sort the items. Thus the items are sorted and frequent pattern is obtained. The frequent
pattern items are retrieved from the database by using hybrid tree (H-Tree) structure. So the
execution time becomes faster. Finally, the frequent pattern item that satisfies the threshold value
is displayed.
A Secure, Scalable, Flexible and Fine-Grained Access Control Using Hierarchic...Editor IJCATR
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
SURVEY ON KEY AGGREGATE CRYPTOSYSTEM FOR SCALABLE DATA SHARINGEditor IJMTER
Public-key cryptosystems produce constant-size cipher texts with efficient delegation
of decryption rights for any set of cipher texts. One can aggregate any set of secret keys and make
them as compact as a single key. The secret key holder can release a constant-size aggregate key for
flexible choices of cipher text set in cloud storage. In KAC, users encrypt a message not only under a
public-key, but also under an identifier of cipher text called class. That means the cipher texts are
further categorized into different classes. The key owner holds a master-secret called master-secret
key, which can be used to extract secret keys for different classes. More importantly, the extracted
key have can be an aggregate key which is as compact as a secret key for a single class, but
aggregates the power of many such keys, i.e., the decryption power for any subset of cipher text
classes. The key aggregate cryptosystem is enhanced with boundary less cipher text classes. The
system is improved with device independent key distribution mechanism. The key distribution
process is enhanced with security features to protect key leakage. The key parameter transmission
process is integrated with the cipher text download process.
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.

Enhancing Data Storage Security in Cloud Computing Through SteganographyIDES Editor
in cloud computing data storage is a significant issue
because the entire data reside over a set of interconnected
resource pools that enables the data to be accessed through
virtual machines. It moves the application software’s and
databases to the large data centers where the management of
data is actually done. As the resource pools are situated over
various corners of the world, the management of data and
services may not be fully trustworthy. So, there are various
issues that need to be addressed with respect to the
management of data, service of data, privacy of data, security
of data etc. But the privacy and security of data is highly
challenging. To ensure privacy and security of data-at-rest in
cloud computing, we have proposed an effective and a novel
approach to ensure data security in cloud computing by means
of hiding data within images following is the concept of
steganography. The main objective of this paper is to prevent
data access from cloud data storage centers by unauthorized
users. This scheme perfectly stores data at cloud data storage
centers and retrieves data from it when it is needed.
A PRACTICAL CLIENT APPLICATION BASED ON ATTRIBUTE-BASED ACCESS CONTROL FOR UN...cscpconf
One of widely used cryptographic primitives for the cloud application is Attribute Based Encryption (ABE) where users can have their own attributes and a ciphertext encrypted by an access policy. Though ABE provides many benefits, the novelty often only exists in an academic world and it is often difficult to find a practical use of ABE for a real application. In this paper, we discuss the design and implementation of a cloud storage client application which supports the concept of ABE. Our proposed client provides an effective access control mechanism where it allows different types of access policy to be defined thus allowing large datasets to be shared by multiple users. Using different access policy, each user only needs to access only a small part of the big data. The goal of our experiment is to explore the right set of strategies for developing a practical ABE-based system. Through the implementation and evaluation, we have determined the various characteristics and issues associated with developing a practical ABEbased
application.

An efficient and secure data storage in cloud computing using modified RSA pu...IJECEIAES
Cloud Computing is the ability to improve the utility or train new human resources without investing in new infrastructure, or add capabilities to existence without the latest software licensing. It expanded the capabilities of Information Technology (IT). From the past few years, cloud computing has developed from a good business concept in the best rising sectors of the IT industry. But more information on individuals and companies was put in the cloud, and concerns began to think about how secure the cloud environment was. Despite cloud surrounding structures, enterprise users still do not want to expand their business in the cloud. Security reduces the growth of cloud computing and continues to spread the market with complexity with data privacy and data protection. The security of cloud computing has constantly been an significant aspect of improved quality of service from cloud service providers. Data storage in the cloud has a problem related to data security. However, cloud computing construct many new security challenges which have not been well examine. In order to ensure that the user's data in the cloud is secure, we have proposed an effective mechanism with a distinctive feature of data integrity and privacy. This paper focusing on problems relating to the cloud data storage techniques and security in virtual environment. We recommend a method for providing data storage and security in cloud using public key Cryptosystem, which uses the concept of the modified RSA algorithm to provide better security for the data stored in the cloud.
Privacy preserving public auditing for secured cloud storagedbpublications
As the cloud computing technology develops during the last decade, outsourcing data to cloud service for storage becomes an attractive trend, which benefits in sparing efforts on heavy data maintenance and management. Nevertheless, since the outsourced cloud storage is not fully trustworthy, it raises security concerns on how to realize data deduplication in cloud while achieving integrity auditing. In this work, we study the problem of integrity auditing and secure deduplication on cloud data. Specifically, aiming at achieving both data integrity and deduplication in cloud, we propose two secure systems, namely SecCloud and SecCloud+. SecCloud introduces an auditing entity with a maintenance of a MapReduce cloud, which helps clients generate data tags before uploading as well as audit the integrity of data having been stored in cloud. Compared with previous work, the computation by user in SecCloud is greatly reduced during the file uploading and auditing phases. SecCloud+ is designed motivated by the fact that customers always want to encrypt their data before uploading, and enables integrity auditing and secure deduplication on encrypted data.
Dynamic Resource Allocation and Data Security for CloudAM Publications
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.
Effective & Flexible Cryptography Based Scheme for Ensuring User`s Data Secur...ijsrd.com
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.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

------------------------------------------------------ABSTRACT---------------------------------------------------
Confidential data in an enterprise may be illegally accessed through a remote interface provided by a multiple-
cloud, or relevant data and archives may be lost or tampered with when they are stored into an uncertain
storage pool outside the enterprise. Therefore, it is indispensable for cloud service providers (CSPs) to provide
security techniques for managing their storage services. To overcome these problems we present a Consistency
as a service auditing cloud scheme. We prove the security of our scheme based data fragmentation on multiple
clouds. So the proposed system has data fragmentation, data security and storage on multiple cloud services.
We used trusted third party to store the data on multiple cloud and find the data access by untrusted cloud
service providers. In this system the client data divide into multiple pieces and send to the multiple clouds with
help of trusted third party. If any of the untrusted cloud service providers try modify the data the alert will send
to trusted third party about illegal access of untrusted cloud service provider.

I. INTRODUCTION
Cloud computing has become commercially popular ,as it promises to guarantee scalability, elasticity,
and high availability at a low cost , the trend of the everything-as-a-service (XaaS) model, data storages
,virtualized infrastructure, virtualized platforms, as well as software and applications are being provided and
consumed as services in the cloud. Cloud storage services can be regarded as a typical service in cloud
computing, which involves the delivery of data storage as a service, including data base like services and
network attached storage, often billed on a utility computing basis, e.g., per gigabyte per month. Examples
include Amazon SimpleDB1, Microsoft Azure storage2, and so on. The usage of the cloud storage services, the
customers can access data stored in a cloud anytime and anywhere using any device, without caring about a
large amount of capital investment when deploying the underlying hardware infrastructures. To meet the
promise of ubiquitous 24/7 access, the cloud service provider (CSP) stores data replicas on multiple
geographically distributed servers. A key problem of using the replication technique in clouds is that it is very
expensive to achieve strong consistency on a worldwide scale, where a user is ensured to see the latest updates.
Actually, mandated by the CAP principle3, many CSPs (e.g., Amazon S3) only ensure weak consistency, such
as eventual consistency, for performance and high availability, where a user can read stale data for a period of
time. The domain name system (DNS) is one of the most popular applications that implement eventual
consistency. Updates to name will not be visible immediately, but all clients are ensured to see them eventually.
Fig. 1.1: An application requires casual consistency
However, eventual consistency is not a catholicon for all applications. Especially for the interactive
applications, stronger consistency assurance is of increasing importance. Consider the following scenario as
shown in Fig. 1. Suppose that Alice and Bob are cooperating on a project using a cloud storage service, where
all of the related data is replicated to five cloud servers, CS1, . . ., CS5. After uploading a new version of there

requirement analysis to a CS4, Alice calls Bob to download the latest version for integrated design. Here, after
Alice calls Bob, the causal relationship [5] is established between Alice’s update and Bob’s read. Therefore, the
cloud should provide causal consistency, which ensures that Alice’s update is committed to all of the replicas
before Bob’s read. In this case, the integrated design that is based on an old version may not satisfy the real
requirements of customers. Actually, different applications have different consistency requirements.
II. RELATED WORK
In “A VIEW OF CLOUD COMPUTING” paper the author proposed the Private-key storage e
outsourcing allows clients with either limited resources or limited expertise to store and distribute large amounts
of symmetrically encrypted data at low cost. Since regular private-key encryption prevents one from searching
over encrypted data, clients also lose the ability to selectively retrieve segments of their data. To address this,
several techniques have been proposed for provisioning symmetric encryption with search capabilities the
resulting construct is typically called searchable encryption. The area of searchable encryption has been
identified by DARPA as one of the technical advances that can be used to balance the need for both privacy and
national security in information aggregation systems. One approach to provisioning symmetric encryption with
search capabilities is with a so-called secure index. An index is a data structure that stores document collections
while supporting efficient keyword search, i.e., given a keyword, the index returns a pointer to the documents
that contain it. Informally, an index is secure" if the search operation for a keyword w can only be performed by
users that possess a trapdoor" for w and if the trapdoor can only be generated with a secret key. Without
knowledge of trapdoors, the index leaks no information about its contents. one can build a symmetric searchable
encryption scheme from a secure index as follows: the client indexes and encrypts its document collection and
sends the secure index together with the encrypted data to the server. To search for a keyword w, the client
generates and sends a trapdoor for w which the server uses to run the search operation and recover pointers to
the appropriate (encrypted) documents.
Symmetric searchable encryption can be achieved in its full generality and with optimal security
using the work of oblivious RAMs. More precisely, using these techniques any type of search query can be
achieved (e.g., conjunctions or disjunctions of keywords) without leaking any information to the server, not
even the access pattern" (i.e., which documents contain the keyword). This strong privacy guarantee, however,
comes at the cost of a logarithmic (in the number of documents) number of rounds of interaction for each read
and write. In the same paper, the authors show a 2-round solution, but with considerably larger square-root
overhead. Therefore, the previously mentioned work on searchable encryption tries to achieve more efficient
solutions (typically in one or two rounds) by weakening the privacy guarantees.
The System introduces new adversarial models for SSE. The first, which we refer to as non-adaptive,
only considers adversaries that make their search queries without taking into account the trapdoors and search
outcomes of previous searches. The second |adaptive| considers adversaries that choose their queries as a
function of previously obtained trapdoors and search outcomes. All previous work on SSE (with the exception
of oblivious RAMs) falls within the non-adaptive setting. The implication is that, contrary to the natural use of
searchable encryption described in these definitions only guarantee security for users that perform all their
searches at once. System addresses this by introducing game-based and simulation-based definitions in the
adaptive setting.In analyzing consistency properties forfun and profit paper the author proposed the system
consider the following distributed file system: a user U pays a server S for storage service, with the goal being
that U can retrieve the stored ¯les anytime and anywhere through Internet connections. For example, U may
store files containing personal data that U may want to later access using his wireless PDA. A user might be
willing to pay for such a service in order to have access to data without carrying devices with large amount of
memory, and to have the data well-maintained by professionals. Such distributed file services already exist, such
as the Yahoo! Briefcase".1 The system expect such services will grow with the expansion of mobile and
pervasive computing. In many cases U will not want to reveal the contents of his files to S in order to maintain
security or privacy. It follows that the files will often be stored in encrypted form. Suppose, however, that later
U wants to retrieve files based on a keyword search. That is, U wants to retrieve ¯les containing (or indexed by)
some keyword. If the files are encrypted, there is no straightforward way for S to do keyword search unless U is
willing to leak the decryption key. A trivial solution that preserves the security of U's files is to have S send all
the encrypted files back to him. This may not be a feasible solution if U is using mobile devices with limited
bandwidth and storage space. An additional complication is that U may naturally also want to keep secret the
keyword that he is interested in as well.

Data-centric consistency : Data-centric consistency model considers the internal state of a storage system,
i.e., how updates flow through the system and what guarantees the system can provide with respect to updates.
However, to a customer, it really does not matter whether or not a storage system internally contains any stale
copies. As long as no stale data is observed from the client’s point of view, the customer is satisfied.
Client-centric consistency : Client-centric consistency model concentrates on what specific customers want,
i.e., how the customers observe data updates. Their work also describes different levels of consistency in
distributed systems, from strict consistency to weak consistency. High consistency implies high cost and
reduced availability. the states that strict consistency is never needed in practice, and is even considered harmful
III. EXISTING METHODOLOGY
There exist various tools and technologies for multiple cloud, such as Platform VM Orchestrator,
Vmware vSphere, and Ovirt. These tools help cloud providers construct a distributed cloud storage platform
(DCSP) for managing clients’ data. However, if such an important platform is vulnerable to security attacks, it
would bring irretrievable losses to the clients. For example, the confidential data in an enterprise may be
illegally accessed through a remote interface provided by a multiple-cloud, or relevant data and archives may be
lost or tampered with when they are stored into an uncertain storage pool outside the enterprise. Therefore, it is
indispensable for cloud service providers (CSPs) to provide security techniques for managing their storage
services.
DISADVANTAGES
Untrusted clouds.
Full data in all cloud.
Low level security.
Need more data space.
Cloud provider can access client's data.
IV. PROPOSED SYSTEM
We present a Consistency as a service auditing cloud scheme. We prove the security of our scheme
based data fragmentation on multiple clouds. So the proposed system has data fragmentation, data security and
storage on multiple cloud services. We used trusted third party to store the data on multiple cloud and find the
data access by untrusted cloud service providers. In this system the client data divide into multiple pieces and
common secret key, send to the multiple clouds with help of trusted third party. If any of the untrusted cloud
service providers try modify the data the alert will send to trusted third party about illegal access of untrusted
cloud service provider.
TTP (TRUSTED THIRD PARTY)
Log In : Here TTP has to log in by using their unique user name and password. TTP is the only authorized
person to access TTP module for security purpose. So others don’t get rights to access this module.
Transfer : In this module TTP view the client uploaded file and transfer them into multiple-cloud. The file will
split into 3 pieces and stored in cloud. TTP is the only authorized person to access TTP module for security
purpose. So others don’t get rights to access this module.
View : In this module TTP view the client uploaded file from multiple-cloud. TTP is the only authorized person
to access TTP module for security purpose. So others don’t get rights to access this module.
Alerts : In this module TTP view the alerts of the security issues of client uploaded files in cloud. That is if any
of CSP try to access client file the alert will send to TTP. TTP is the only authorized person to access ttp
module for security purpose. So others don’t get rights to access this module.
CSP (CLOUD SERVICE PROVIDER)
Log In : Here CSP has to log in by using their unique user name and password. CSP is the only authorized
person to access CSP module for security purpose. So others don’t get rights to access this module.
4. Two Level Auditing Architecture To Maintain…
www.theijes.com The IJES Page 35
View :In this module CSP view the client uploaded file in their cloud as encrypted format. If CSP try edit the
client file the alert will send to TTP. CSP is the only authorized person to access TTP module for security
purpose. So others don’t get rights to access this module.
CLIENT
Register : Here client has to register their details to log In. It contains unique user name and password. Client is
the only authorized person to access this module for security purpose. So others don’t get rights to access this
module.
Log In : Here client has to log in by using their unique user name and password after registration. Client is the
only authorized person to access this module for security purpose. So others don’t get rights to access this
module.
Upload : In this module client upload their files means give to the correct secret key. The secret key is wrong
means the file is not uploaded. And also enter the expire date. That date only visible the file in cloud. Client is
the only authorized person to access this module for security purpose. So others don’t get rights to access this
module.
View : In this module client view their uploaded file from multiple-cloud. Client can edit the particular split.
The updates will changed on cloud. Client is the only authorized person to access this module for security
purpose. So others don’t get rights to access this module.
Download : In this module client download their files means give to the correct secret key. The secret key is
wrong means the file is not download. Particular date only client download the upload files.. Client is the only
authorized person to access this module for security purpose. So others don’t get rights to access this module.
ADVANTAGES
Trusted third party.
Incomplete data in all cloud.
Security alerts, encryption data.
Need low data space.
Cloud provider can't accessing client's data.

VI. ALGORITHM USED
LOCAL CONSISTENCY AUDITING
Local consistency auditing is an online algorithm (Alg. 1). In Alg. 1, each user will record all of his
operations in his UOT. While issuing a read operation, the user will perform local consistency auditing
independently. Let R(a) denote a user’s current read whose dictating write is W(a), W(b) denote the last write in
the UOT, and R(c) denote the last read in the UOT whose dictating write is W(c). Read-your-write consistency
is violated if W(a) happens before W(b), and monotonic-read consistency is violated if W(a) happens before
W(c). Note that, from the value of a read, we can know the logical vector and physical vector of its dictating
write. Therefore, we can order the dictating writes by their logical vectors.
Initial UOT with ∅
while issue an operation op do
if op = W(a) then
record W(a) in UOT
if op = r(a) then
W(b) ∈ UOT is the last write
if W(a) → W(b) then
Read-your-write consistency is violated
R(c) ∈ UOT is the last read
if W(a) → W(c) then
Monotonic-read consistency is violated
record r(a) in UOT
GLOBAL CONSISTENCY AUDITING : Local consistency auditing is an online algorithm (Alg. 1). In Alg.
1, each user will record all of his operations in his UOT. While issuing a read operation, the user will perform
local consistency auditing independently. Let R(a) denote a user’s current read whose dictating write is W(a),
W(b) denote the last write in the UOT, and R(c) denote the last read in the UOT whose dictating write is W(c).
Read-your-write consistency is violated if W(a) happens before W(b), and monotonic-read consistency is
violated if W(a) happens before W(c). Note that, from the value of a read, we can know the logical vector and
physical vector of its dictating write. Therefore, we can order the dictating writes by their logical vectors.
Each operation in the global trace is denoted by a vertex
for any two operations op1 and op2 do
if op1 → op2 then
A time edge is added from op1 to op2
if op1 = W(a), op2 = R(a), and two operations come
from different users then
A data edge is added from op1 to op2
if op1 = W(a), op2 = W(b), two operations come from
different users, and W(a) is on the route from W(b) to
R(b) then
A causal edge is added from op1 to op2
Check whether the graph is a DAG by topological sorting
VII. CONCLUSION
The system proposes a consistency as a service (CaaS) model and a two-level auditing structure to help
users verify whether the cloud service provider (CSP) is providing the promised consistency, and to quantify the
severity of the violations, if any. With the CaaS model, the users can assess the quality of cloud services and
choose a right CSP among various candidates, e.g., the least expensive one that still provides adequate
consistency for the users’ applications .For our future work, we will conduct a thorough theoretical study of
consistency models in cloud computing.
