Abstract

A number of content viewing systems that use electronic money have been proposed recently. These systems’ access control uses license information stored in the specific hardware such as a set-top box (STB), which is distributed by broadcasters or communication carriers. However, such an access control decreases the usability of the system, since users cannot carry around a STB. To solve this problem, other content viewing systems uses an electronic prepaid ticket and a tamper resistant module (TRM) for digital broadcasting. In such a system, license information stored in the TRM is transferred to a user’s mobile terminal, such as a cellular phone. The user, who carries this mobile terminal, can view contents away from home. This kind of system requires the license information to be managed securely and the electronic prepaid ticket payment to be performed correctly. In this paper, we propose another system that meets these requirements and enables anonymous viewing with a low CPU cost.
