This research aims to construct a content distribution protocol that preserves the content provider’s security and users’ privacy. The protocol can improve Digital Rights Management (DRM) that is required to provide balanced protection for the content provider and the users in a content distribution system. The concept of oblivious transfer (OT) is utilized to fulfill the DRM requirement. The OT concept allows a sender to securely send a set of information to a receiver in such a way that, at the end of the protocol, the receiver cannot learn more than he was supposed to learn, while the sender cannot determine what the receiver has learned. Assuming that tamperproof device exists, the constructed protocol achieves perfect security for the content provider and privacy for the users. This oblivious content distribution ultimately enables DRM to be a privacy-aware protection system. The system does not merely focus on content providers’ rights, but also seriously considers users’ privacy protection.
