Abstract

When subscribers watch pay-TV programs, they get keys for decrypting the transmitted content and they are charged a fee, so these schemes enable content providers to get information about the contents that the subscribers watched, and the anonymity disappears. Recently, people have been taking the preservation of privacy seriously, and they do not want their private information to be disclosed even to the content provider of pay-TV. Moreover, content providers require a secure and correct revenue sharing scheme. In this paper, we propose an anonymous pay-TV system with secure revenue sharing to meet such requirements.
