To increase the security issues in a private cloud storage from traitor we propose Encrypting File Sharing And Synchronizing Using Efficient Traitor Tracing And Revocation. It implements the revocation algorithms to block the traitors and generates a traitor tracing technique to trace the presence of the traitors. The proposed methodology is suitable for a private cloud storage which can be modified in future to support public clouds. It propose, if an user uploads his data to a cloud storage server the user will be provided with a private and public key. The public key is used to verify that the user belongs to the concerned private cloud. In case of any abnormal activity the proposed methodology revocates the specific user using IP and MAC addresses and provides the longitude and latitude information to the data owner. In addition pattern matching, SQL injection and anomaly detection are proposed to maintain the privacy and security.
