Description This paper describes an experimental digital rights management architecture which uses digital watermarking and encryption to protect the content. In addition to cryptographically protected media content, the deliverable package can also include a teaser that the user is allowed to consume freely. The content is identified with an attack-resistant watermark that is used to automatically acquire a license needed to consume the rest of the content. The watermark is also used to prevent conforming players from showing protected content if the encryption has been removed. The architecture uses a public key infrastructure to handle licenses. 1.
