摘要：Several data hiding methods have been recently proposed which can provide the security by hiding thedata. Integrity of the data is having risk in the cloud. The Cloud Server (CS) could plan to hide the data, when data losscaused by server hacks or failures to keep up reputation. The randomization is predictable to increase the security of thesystem and also increase the capacity. One of the good cryptographic solutions to this problem is Cipher text AttributeBased Encryption (CP-ABE). Key technology is one of the significant factors in information sharing. In proposedsystem by applying encryption the information system presents an additional challenge with regard to the userrevocation. Dynamic revocation of cipher policy attribute based encryption mechanism is potential to eliminate accessfrom users without delivering new keys to other users. In this proposed system users individually request the owner toadd, update, and modify or remove the value of one attribute freely without knowledge of other attribute.
