An Approach of Program Analysis Prevention for Information Protection

The evolution of mobile technologies will enable us to realize the ubiquitous computing environment. In such environment, a user´s mobile terminal manages his sensitive information and assists in his activities. At the same time, information leakage will become more serious social problems. In this paper, we propose a framework which protects user´s sensitive information according to a way the user supposes safe. In the framework, a user offers a program, which implements a way the user supposes safe, to an information recipient. And then, the information recipient makes use of the user´s sensitive information through the program. In this manner, the user can protect his sensitive information. The framework, however, has a problem, by which the information recipient may analyze the program and obtain some sensitive information. In this paper, we introduce a tamper-proof device and trust relationship for a solution of this problem.
