Abstract— Cloud computing is a general term for the delivery of hosted services over the Internet. In cloud environment data’s should be stored in encrypted manner to protect it from illegal access of data stored in the cloud service provider. To secure the data of the cloud user’s, here proposed a TLE scheme with delegated access rights to the cloud users where the delegated access rights can be maintain and managed by Data Owner. Here decomposing access right policies such that it satisfies TLE scheme. The proposed system includes a Merkle Hash Tree that can used for verification of contents of the large data structures that is stored in the cloud. It provides privacy for user’s data and keep it confidentially while enforcing attribute based ACPs. Thus the proposed system prevents it from unauthorized access of data stored in the cloud and provides various levels of verification of data.
