摘要：Cloud storage becomes one of the critical services,because users can easily modify and share data withothers in cloud.To ensure the integrity of the shared data, some schemes have been designed to allow public verifiers toefficiently audit data integrity without retrieving the entire users’data from cloud.In this project, we propose a newprivacy-aware public auditing mechanism for shared cloud data by constructing a homomorphic verifiable groupsignature. In order to reduce the burden on users, a trusted third party auditor(TPA) is engaged to conduct theverification, which is called public auditing.It can verify the accessed data without looking what the data is ,henceprivacy is preserved.The TPA is plays an intermediate role between the data owner who is uploading the files into thecloud and the ordinary member who is downloading the files from the cloud.
