The invention provides a method, apparatus and system for the secure distribution of content such as audiovisual content in a way that prevents users from misusing the content and provides a mechanism for tracking pirated material back to the original location of misappropriation. A security device incorporates encryption methods to insure the broadcast encryption key remains secure. A marking device incorporates, for example, digital watermarking methods that attach to the content information to identify a location of origin of the misappropriation, such as a Set-top Box (STB) and/or smart card.
