Anonymous technology is one of the main technologies used to solve the problem of privacy data disclosure.In order to enable users to enjoy the life convenience brought by the development of science and technology,this paper uses data desensitization to transform and modify sensitive data under the given rules and strategies,so as to achieve the privacy data protection.Data desensitization technology can meet the needs of privacy data protection in different application scenarios.The privacy data still has reading value after using the two methods of desensitization to protect,largely solved the problem of the sensitive data used in an untrusted environment.This paper firstly analyzes the method of data anonymity and introduces the data desensitization technology in detail.Then,in order to solve the existing problem of data protection,this paper studies privacy data protection models based on anonymity from different angles,and introduces research in detail respectively.The related research work of this paper is just as follows:(1)Research on privacy data protection based on the perspective of user role:due to the users have different role in real life,and also they have different degrees of protection demands for different data,so this paper studies the sensitive data protection model from the perspective of user role,and furthermore this paper analyzes it from two angles namely static data desensitization and dynamic data desensitization respectively.(2)Research on continuous query protection of sensitive data based on the perspective of session:due to the data protection method based on user role cannot support the feature of the continuous query,cannot prevent user from using the acquired data to realize linked attack,so this paper studies the continuous query protection of sensitive data base don the perspective of session.(3)Research on privacy data protection based on self-regulated access time:dues to the session is managed by the service side in the continuous query protection method based on session,the client-side cannot control the time,so the client-side can not realize the personal set service of the user's visit time,so this paper studies the sensitive data protection model by self-regulated access time.(4)Research on privacy data protection from the perspective of file sharing:in real life,we almost entirely share data or publish data in a form of file,the above methods proposed in the paper cannot meet this requirement,so this paper studies the privacy data protection from the perspective of file sharing.
