Research on context-aware architecture for personal information privacy protection

In pervasive environment, context-aware service provider can use personal information to customize the adequate services for end users. Personal information is people´s privacy concern. Therefore, people need privacy control methods. In this paper, we analyzed privacy control from two aspects: personal privacy model about information disclosure and the function of context-aware service provider. According to the analysis, we designed the components about context-aware privacy control in order to minimize the burden of personal privacy decision about personal information disclosure. The simulation experiment shows that it is possible method for the proposed privacy protection mechanism. Finally, we also proposed conceptual context-aware architecture to control personal information disclosure.
