Anonymous authentication is a method for privacy protection in web service. But, the nature of anonymous authentication, access control of service is seemed impossible because it doesn't know the user's characteristics. In our paper, we propose an anonymous authorization framework which uses qualification certificate and anonymous authentication based on Short Group Signatures. Also, our qualification certificate is used as payment token. By using our proposed authorization protocol, users can use anonymous authentication, anonymous authorization, and anonymous payment in web service.
