摘要:
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 application of content usage enforcement actions, may be organized such that some or all of the operations can be conducted at different times by different devices. These operations can be conducted by one or more trusted devices that reside in a networked environment. Real-time access to a content can also be facilitated by utilizing existing watermark extraction records. To facilitate real-time access to the content, the extraction records may contain segmented authentication information that correspond to particular segments of the content that is being accessed. Additionally, or alternatively, new watermark extraction operations can be conducted in real-time to produce new watermark extraction records.
