AbstractCurrent Pay-TV systems enable service providers to easily acquire personal data, e.g. the customers' watching habits, which will make the customers uncomfortable or cause them inconvenience. Although many privacy protection schemes have been proposed, they only protect the customer privacy from abuse by outsiders, not the service providers. This paper develops a new conditional access system (CAS) mechanism - 'e-ticket' - for Pay-TV systems to protect customer privacy from abuse by both outsiders and providers, while protecting both the customers and the providers against double-spending, loss, misuse, and/or stealing of the e-ticket. This article also demonstrates that the combination of the partial blind digital signature and anonymous digital signature makes Pay-TV systems robust and fair than before.
