Cloud security is an important aspect in centralized data management in public resources. By increasing data processing and service access level, the integrity level be deformed due to data leakage, spoofing, and key leakages because of user behavioral approach to access the data is malpractice to own data. So the owner policy become unauthenticated to access the data rapidly increasing by non-authenticated users. To resolve this problem, propose a Service Level Integrity Proofing (SLIP) Verified Data Security. Based on Decentralized Chain-Link Provable Advanced Encryption Standard (DCLP-AES) in Cloud Environment. This proposed system verifies each service access policy of user which is relatively posed to aggregate the owner certificate signing at chain-link verification. The verification can be time-stamped after the transaction is recorded into integrity weight. This proposed system improve the security levels based on integrity security signing level to protect the data compared to the other system as well high performance in security.
