In today's computing world in the cloud user can easily modify and share data as group. The main issues in the cloud computing was data privacy, data integrity, data access by unauthorized users. TTP (Trusted Third Party) is used to store and share data in cloud computing. To verify integrity of data, users in the group need to compute signature on all the blocks in shared data. In shared data different blocks signed by different user due to data modification performed by different users. User revocation is biggest security reason in data sharing in the group. Once user is revoked from the group, the blocks which were previously signed by this revoked user must be resigned by an existing user. This allows an existing user to download the corresponding part of shared data and re-sign it during user revocation. This task is very inefficient due to the large size of shared data in the cloud. PANDA Plus is the new public auditing mechanism for the maintaining integrity of shared data with efficient user revocation in the cloud. The idea of proxy re-signature, we allow the cloud to re-sign a block behalf of existing user, so the existing user do not need to download and re-sign blocks by themselves. As well as public auditor, this audits the integrity of shared data without retrieving entire data from the cloud. It also uses batch auditing to verify multiple auditing tasks simultaneously.
