Public Auditing for Shared Cloud Data with Group User Revocation

In cloud computing data to be shared in cloud, in the process to be performed in sharing data to be secure manner in publically, revocation to be used for the purpose of existing user to revoked resign that the process of entering to the cloud then getting data and upload the information from the cloud. In this concept, we propose it is cloud audit the efficient by the revocation user. More proxy a signature by resign by the existing users, public auditing it is a shared data to be verifiable, it is no need without process of sharing data from cloud, in this mechanism batch auditing verify multiple auditing simultaneously, multiple it is the performance to be highly efficient in the asymmetric key algorithm to be used securely performed. It is the purpose of easily get the information from the cloud sequentially, experimentally results do that improve efficiency in user revocation.
