摘要：Cloud computing is a recent generation technology which efficiently support the client oriented services. Now days there are a number of applications which uses the cloud storage service for storing and accessing information. In such conditions the data owner management and privacy preservation cryptographic techniques are used frequently. We represented a privacy preserving access control scheme for data storage, which supports authentication and decentralized key management. As people are more concerned about their identity privacy these days, the identity privacy also needs to be protected before the cloud enters our service. Cloud computing system should be salient in the case of security in which some part of the system is compromised by attackers. AnonyControl to address to the data privacy, and the user identity privacy in existing access control schemes. Here we use the user revocation in users to activating and deactivating users. Revoked users are maintained in the revoke user list and make publicly available in the cloud. User revoke will decide which user should may in cloud storage server to access data or which will remove. The data access privilege will be depending upon misbehaviour of user in cloud server.
