With application and popularization of e-commerce and rapid development of Internet technology, some trade companies or individuals adopt various technological means to obtain and utilize the network user's personal secret information improperly, have infringed the network user's privacy right. So how to construct a network privacy protection datum right system to effectively protect network user's privacy datum rights has become the important subject that demanding prompt solution at present. This paper direct the safe protection question about network personal secrets tactics and launch the discussion in terms of technology and applicant, propose the realization way on the basis of inquiring service end centre mode of rewrite technology database.This paper has introduced the research background and the main classification of network privacy protection and studied the principle of realizing network privacy protection strategy. It carries on the main thought and the technical characteristic of each kind of network privacy protection strategy, summarized the main question exists in the privacy protection strategy mechanism, described emphasis in the P3P realization structure by taking the client side as the central and the P3P system structure of taking the server as the central. Through analyzing different existing P3P realization plan, this paper considered to enhance the P3P privacy protection strategy's performance in the existing realization system structure by improving the data sheet pattern which is used for saving the privacy strategy.Aiming at the most essential question of avoiding divulging the user's privacy data in privacy strategy protection mechanism at present, this paper considered protecting the main body data message in the database, and carrying on the investigation into the smallest privacy data item contains in the database when carrying on the processing query. Contrasting the existing strategy realization way, it will spend more time and cost by revising the existing application procedure code, but the workload of amending existing application procedure will be very slightly by protecting the privacy strategy in the database.In this paper, proposed a solution mentality by limited disclosuring the privacy in the database. The main method and mentality are stores up the privacy strategy and the user's choices in the database, and reflect these privacy semanticists through rewriting the query mechanism. In detail, it is intercepts an introduction inquiry in this mechanism, moreover increases the corresponding inquiry to reflect the privacy strategy and the parameter choices of main body information.
