A Survey on the Architectures of Data Security in Cloud Storage Infrastructure

Cloud computing is a most alluring technology that facilitates conducive, on-demand network access based on the requirement of users with nominal effort on management and interaction among cloud providers. The cloud storage serves as a dependable platform for long term storage needs which enables the users to move the data to the cloud in a rapid and secure manner. It assists activities and government agencies considerably decrease their economic overhead of data organization, as they can store their data endorsement vaguely to third-party cloud storage sources than preserving the data centers on their personal. Cloud storage allows users to accumulate their data at a remote location and have the on-demand high superiority cloud requests without the burden of restricted hardware and software organization. Along with the widespread benefits on cloud computing, however, security issues with cloud data storage are arising in terms of confidentiality, integrity and reliability. Although the profits are obvious, such a service is also turning down user’s corporeal control of their outsourced data, which unavoidably facades novel security dangers towards the accuracy of the data in cloud. This paper provides a comprehensive survey of major security issues that exists in cloud data storage. We also conduct extensive empirical studies and analysis of different techniques which provides security fortification for outsourced data in cloud computing environment.
