Application And Research Of Privacy Access Control Model Based On Multi-agent Technology

Nowadays,when users acquire and enjoy convenient information services on the Internet,they need to provide their own user privacy information to various Internet information service platforms,so as to support the normal implementation of convenient network information services.The provider of information services may access,operate and expose users' privacy information without authorization after obtaining users' privacy information on the Internet,causing serious disclosure of Internet users' privacy information and bringing serious troubles to users' normal work and life.The Internet information platform meets the functional requirements required by users and protects users' personal privacy information,which is currently an important theme for protecting the rights and interests of Internet users.At present,the internal and foreign research institutions and staff of the Internet information service platform are focusing on how to meet the functional requirements of users and optimize the investment portfolio of information services.Personal privacy protection for the users,mainly for privacy information is encrypted,privacy in the access strategy analysis and position in the privacy of the security research,etc.,These privacy protection method is lack of the semantic analysis of user's privacy preference and practice in multiple platforms.Due to the lack of current research,this paper focuses on protecting the privacy of online users.This paper presents a privacy access control protection method based on multi-agent technology.The method is mainly used to solve the current network service provider's ineffective protection of user privacy,and provides a distributed personalized privacy access control tool for the privacy protection of users in the network information service platform,which can control the privacy access in multiple platforms.The main work of this paper is as follows:(1)This thesis constructs a privacy domain ontology.The privacy ontology is based on the privacy domain model and privacy domain knowledge proposed in this paper,which provides semantic support for privacy protection services.It provides the basis of ontology reasoning for the following model system.(2)In this thesis,a privacy access control model based on multi-agent technology is designed.Firstly,the privacy preference described by users' natural language is translated into semantic Web rules,which provides reasoning rules for privacy protection services.Then a distributed privacy access control platform is designed by reasoning rules of privacy ontology,access control model and multi-agent technology.This platform not only recommends appropriate service platforms according to users' privacy preferences,but also provides personalized protection for users' privacy information.(3)In this thesis,a prototype system is established to implement privacy services.The rationality and effectiveness of this method were reviewed three times.
