Public Auditing and privacy preserving data sharing in the cloud
Dagudu Venkatesh, G. Karthik Reddy · 2015
In this paper, we propose privacy preserving auditing scheme that exploits the ring signature to calculate verifications needed to audit data integrity. In this proposed approach, the identities of the user are kept private from public verifier and dynamic groups are supported –that is a new user can be added into the group and an existing group member can be revoked during data sharing.
