Program Conversion for the Protection of Personal Information

Some of Internet services request us to provide our personal information. When we use their services, we have to provide our personal information even if we cannot trust their service providers. This may cause the abuse of their personal information. Therefore, we propose a framework that prevents service providers from abusing users' personal information. In our framework, a user selects a method to use his/her information, and compels the service provider to use the method. Since the personal information is used through the method selected by the user, the user is able to prevent the service provider from the abuse of his/her personal information. Thus, the user can relief to provide his/her personal information to the service provider. We have some problems to be solved for the realization of our framework. In this paper, we discuss a way to install a method selected by a user into a program a service provider has.
