Cloud storage is an exclusive resource in cloud computing, which helps to store and share the data on cloud storage server. Clients upload the data and its hash information n server together on cloud storage. The file owner always concern about data security like privacy and unauthorized access to third party. The owner also wants to ensure the integrity data during communication process. To ensure integrity, we propose a framework based on third party auditor which checks the integrity and correctness of data during audit process. Our aim is to design custom hash for the file which is not only justifies the integrity but also version information about file.

Numerous cloud service certifications (CSCs) are emerging in practice. However, in their striving to establish the market standard, CSC initiatives proceed independently, resulting in a disparate collection of CSCs that are predominantly proprietary, based on various standards, and differ in terms of scope, audit process, and underlying certification schemes. Although literature suggests that a certification's design influences its effectiveness, research on CSC design is lacking and there are no commonly agreed structural characteristics of CSCs. Informed by data from 13 expert interviews and 7 cloud computing standards, this paper delineates and structures CSC knowledge by developing a taxonomy for criteria to be assessed in a CSC. The taxonomy consists of 6 dimensions with 28 subordinate characteristics and classifies 328 criteria, thereby building foundations for future research to systematically develop and investigate the efficacy of CSC designs as well as providing a knowledge base for certifiers, cloud providers, and users.
