Digital watermarking is the art of hiding information in digital contents such as images, audio clips, and videos. We can take advantage of this technique by adding author information as well as buying information for a digital purchase. In this paper we propose a protocol for secure anonymous digital purchase to deter buyers from executing illegal redistribution of digital contents. We propose a protocol to allow merchants to obtain a proof of treachery from dishonest buyers.
