摘要： Systems and methods are provided for protecting electronic content from the time it is packaged through the time it is experienced by an end user. Protection against content misuse is accomplished using a combination of encryption, watermark screening, detection of invalid content processing software and hardware, and/or detection of invalid content flows. Encryption protects the secrecy of content while it is being transferred or stored. Watermark screening protects against the unauthorized use of content. Watermark screening is provided by invoking a filter module to examine content for the presence of a watermark before the content is delivered to output hardware or software. The filter module is operable to prevent delivery of the content to the output hardware or software if it detects a predefined protection mark. Invalid content processing software is detected by a monitoring mechanism that validates the software involved in processing protected electronic content. Invalid content flows can be detected by scanning the information passed across system interfaces for the attempted transfer of bit patterns that were released from an application and/or a piece of content management software.

摘要： Systems and methods are disclosed for managing and protecting electronic content and applications. Applications, content, and/or users can be given credentials by one or more credentialing authorities upon satisfaction of a set of requirements. Rights management software/hardware is used to attach and detect these credentials, and to enforce rules that indicate how content and applications may be used if certain credentials are present or absent. In one embodiment an application may condition access to a piece of electronic content upon the content's possession of a credential from a first entity, while the content may condition access upon the application's possession of a credential from a second entity and/or the user's possession of a credential from a third entity. Use of credentials in this manner enables a wide variety of relatively complex and flexible control arrangements to be put in place and enforced with relatively simple rights management technology.
