Abstract
An anonymous authentication-based private information management (PIM) system and method are provided. The PIM method includes receiving an anonymous certificate not including user information from an anonymous certification authority; generating an anonymous document including the anonymous certificate and some of the user information; and providing the anonymous document to a web service provider so as to be authenticated and thus provided with a web service by the web service provider. Thus, only a minimum of user information may be provided to the web service provider. In addition, it is possible to strengthen a user's right to self-determination and control over the exposure and use of his or her personal information by allowing a user to manage his or her own personal information or entrusting the PIM server to manage user information. Moreover, it is possible to protect the privacy of a user by preventing the exposure of user information.
