  • Patent number: 7031471
    Abstract: A trusted rendering system for use in a system for controlling the distribution and use of digital works. A trusted rendering system facilitates the protection of rendered digital works which have been rendered on a system which controls the distribution and use of digital works through the use of dynamically generated watermark information that is embedded in the rendered output. The watermark data typically provides information relating to the owner of the digital work, the rights associated with the rendered copy of the digital work and when and where the digital work was rendered. This information will typically aid in deterring or preventing unauthorized copying of the rendered work to be made. The system for controlling distribution and use of digital works provides for attaching persistent usage rights to a digital work. Digital works are transferred between repositories which are used to request and grant access to digital works.

  • Publication number: 20060041421
    Abstract: Legality expressions are systematically pre-processed, organized, and stored to achieve faster real-time response, improved predictability, and increased reliability for queries against a large volume of legality expressions. Exponential improvements in both the time to locate the set of legality expressions matching specified search criteria and the processing costs of evaluating the request against the matching legality expressions are achieved using the disclosed systems, devices, and methods. The systems, devices, and methods are unique to the optimization of legality expression processing, but they can also enable the use of other optimization techniques for processing large amounts of data.
