A Cloud Storage System for Preserving Privacy and Data Integrity of User

Cloud computing offers well-known services for storing user data and it gives attention towards a broad set of policies, technologies and controls deployed to facilitate security for applications and data. As the more and more businesses using the cloud, security is becoming main problem in the cloud environment. It is very important that companies work with partners who knows best practices of cloud security and which provides transparency for their solutions. Many security solutions today rely on the authentication for providing security but it didn-t solve the privacy issues while sharing data over the cloud storage. Users data access request itself may reveal users private information no matter his request approved or not. So this become the important in data sharing in the cloud computing. In this paper we proposed a system which addresses the above mentioned issue. The proposed system uses the concept of data anonymity for anonymous matching of data access request. Our system also provides the data auditing functionality to protect the integrity of users shared data.
