Many online services on the Internet give users an ID without strictly identifying the user, which enables users to access the service anonymously. Therefore, under the cover of anonymity, some malicious users perform illegal act which damages online service providers and/or other users. It is difficult to shut out such users as long as you can acquire multiple IDs. While it is possible to restrict users to have exactly one single ID, existing methods to achieve this require user's privacy information, which is not desirable for privacy protection. In this paper, we propose authentication infrastructure which restricts users to have single IDs, imposed through third party verification by a trusted certificate authority. As users do not have to submit their privacy information and have different IDs for different service providers, user's privacy is protected.
