A user profile set anonymization algorithm is proposed in this paper.Firstly,the user profile model is extracted to compute similarityand cluster with the computing result.Secondly,exponential noise is added in the cluster process for differential privacy.Finally,the anonymity data are released.Experimental results demonstrate that the proposed anonymization cluster algorithm promotes data utility and level of privacy protection.
