Today, cloud storage turn out to be one of the critical services, because users can easily amend and share data with others in cloud. However, the integrity of shared cloud data is vulnerable to inevitable hardware faults, software failures or human errors.Inthis paper, we propose a new privacy-aware public auditing mechanism for shared cloud data by making ahomomorphic valid group signature. Nothing like the existing solutions, our plan requires at least team professionalsto recover a track key cooperatively, which removes the mistreatment of single-authority ability and provides noflammability. Furthermore, our scheme means that group users can trace data changes through the specifiedbinary tree; and can recover the latest right data stop when the existing data stop is destroyed. Also, the formalsecurity analysis and investigational results reveal that our system is probably secure and efficient.
