简介
Methods, devices, and computer program products facilitate the application of a content use policy based on watermarks that are embedded in a content. Watermark extraction and content screening operations, which can include the appli cation of content usage enforcement actions, may be orga nized such that some or all of the operations can be con ducted at different times by different devices. These operations can be conducted by one or more trusted devices that reside in a networked environment. The authenticity of various devices can be verified through the exchange of certificates that can further enable such devices to ascertain capabilities of one another. Based on the ascertained capa bilities, an operational configuration for conducting water mark extraction and content screening can be determined.
