As the broadband IP networks have spread rapidly, the number of users of content distribution services has grown. In these services, it is desirable that the user’s usage history and their preferences provided are kept confidential in order to protect their privacy. On the other hand, the usage charges need to be calculated correctly based on the contents received by the user. In the above situation, it is not desirable to charge the user at the instant he or she receives it because the usage history can be deduced from the price of each content. In this paper, we propose a generic scheme for content distribution and charging; this scheme that satisfies this privacy requirement by keeping the usage history confidential. Furthermore, we present a new construction based on the group signature proposed by Ateniese et al. In this construction, the computation and communication costs depend only on the number of contents purchased and not on the total number of available content.
