Cloud computing has become a prominent technology due to its important utility service; this service concentrates on outsourcing data to organizations and individual consumers. Cloud computing has considerably changed the manner in which individuals or organizations store, retrieve, and organize their personal information. Despite the manifest development in cloud computing, there are still some concerns regarding the level of security and issues related to adopting cloud computing that prevent users from fully trusting this useful technology. Hence, for the sake of reinforcing the trust between Cloud Clients (CC) and Cloud Service Providers (CSP), as well as safeguarding the CC’s data in the cloud, several security paradigms of cloud computing based on a Third-Party Auditor (TPA) have been introduced. The TPA, as a trusted party, is responsible for checking the integrity of the CC’s data and all the critical information associated with it. However, the TPA could become an adversary and could aim to deteriorate the privacy of the CC’s data by playing a malicious role. In this paper, we present the state-of-art of cloud computing’s privacy-preserving models (PPM) based on a TPA. Three TPA factors of paramount significance have been discussed: TPA involvement, security requirements, and security threats caused by vulnerabilities. Moreover, TPA’s privacy preserving models have been comprehensively analyzed and categorized into different classes with an emphasis on their dynamicity. Finally, we discuss the limitations of the models and present our recommendations for their improvement.

“…For the four participants, four x values are picked randomly, and substituted in the polynomial function by setting p value to be 251 which is the largest prime number less than 255 (maximum gray image value). Four shares are computed as (1, 222), (2,83), (3,195) and (4,56). They become the first pixel in four image shares.…”

With the recent popularity of cloud computing, public cloud infrastructure is now being offered by many vendors. Many small, medium as well as large enterprises are now moving into public cloud due to its significant business advantages, flexibility and reduced cost. However, public cloud environments are less secure and the complete setup consists of vulnerable public networks. Data is sent typically over the internet or very large, open networks which are vulnerable to security attacks. Protection of data is hence primarily important in a public, third-party cloud. This paper is an extension of the previously published work and discusses a general approach to distribute and transmit data in an unsecured environment. We propose an application layer technique of protecting important data in public clouds which are transmitted over public networks. We use the concept of secret sharing to derive a technique which provides an efficient and effective solution to the above problem. We show how data can be protected without any complex cryptographic techniques that are generally inefficient in cloud environment.

“…The result showed that the system can be applied without need high hardware requirement such as 128 megabyte RAM, 1.2GHz processor. P.Varalakshmi, et al [5] proposed secure cloud computing data store using RSA data encryption algorithm to provide security and privacy for user data on cloud storage. Cloud remote server may be under attack by hackers this breakable the privacy of user or organization data by steels it.…”

There are many hot topics related to cloud computing paradigm, and one of these important fields is data security in cloud data storage that aims to make users data more secure and for ensure privacy for users. In this paper we intend to introduced a comprehensive study on security of cloud data store, since there have been little works deals with. The introduced papers here addressed this problem from different views, some deals with encryption algorithm while other researchers made comparisons between different techniques. On the other hand, some papers proposed new technique or made some enhancements on existing ones either depends on statistical or un-statistical encryption algorithms. Till now there are no optimal suggested solutions that solve the security on cloud data store.
