Abstract: In response to the issue that user behaviors threaten security and privacy in mobile cloud computing,a ring-identity mechanism based on the third party was proposed in this paper.The access control of user’s identity ensures that it can not be able to track user’s virtual identity by providing user with ring identity certificate.The focus of data auditing is on how to schedule data records and generate ring signature so as to avoid leaking position of critical data and to protect user’s privacy.Theoretical analysis shows that our framework achieves good security and privacy perfor-mance considering the threat of user’s behavior records.

Key words: Mobile cloud computing,Privacy,Identity authentication,Ring signatures,Access control,User behavior
