USER ATTRIBUTE BASED DATA ACCESS AND SHARING ON CLOUD COMPUTING ENVIRONMENT

It is more important to secure users sensitive data in the distributed cloud environment. There has been lot of researches going on managing users and user's data in the cloud server. But allowing users to store, access and share data between them makes a serious security issues that can spoil entire cloud environment. The aim of this paper is to provide a secure method to make users store and retrieve data in server with specific access control. A user should not access data that not belongs to him. The proposed technique of User Attribute Based Data Access and Sharing will be technically a better method to offer. This enables data management simpler and also prevents invalid access control. It also addresses user session revocation of invalid user and replay attack avoidance.
