An analysis on data Accountability and Security in cloud

Cloud computing is one of the best emerging parameter in IT industry which provides on demand services. It uses Central remote server and internet for maintaining data and applications. Users can access their files and applications through internet access. As it is publically available so data security must be required. In this paper, we have analyzed different security and application aspects of cloud computing such as integrity, confidentiality, transparency, accountability, availability, assurance There are many security issues related to cloud computing which includes users data handled remotely by many users, user should know how their data get processed on to the cloud. To deal with it many security and accountability models exit. Here we discussed some of them like Privacy manager in cloud, RSA based storage security system, Cloud computing data security model and Cloud information accountability framework. We have analyzed these four models and finally conclude that which model is suited for which type of application or service. Proposed system focused on developing Lightweight Framework for Accountability and Security.
