This email is notice that a Chair of the XML Encryption WG has received a pointer to the following patent [1]. I've not communicated with representatives of the inventors nor garnered any other information about this claim. Since I'm obligated to disclose patents that I'm aware of, I need to forward such pointers on though the following, of course, applies: http://www.w3.org/Encryption/2001/Disclosures.html The W3C does not take a position regarding (1) the validity or scope of any intellectual property right or other rights that might be claimed to pertain to the implementation or use of the technology, nor (2) the extent to which any license under such rights might or might not be available.

To give users the most power and flexibility, a standard object that has the capability to embed objects is used. To allow users even more flexibility, a standard object tracking mechanism is used that allow users to distribute multiple encrypted embedded objects to other individuals in a single encrypted object. By effecting compartmentalization of every object by label attributes and algorithm attributes, multi-level multimedia security is achieved. -- Joseph Reagle Jr. http://www.w3.org/People/Reagle/ W3C Policy Analyst mailto:reagle@w3.org IETF/W3C XML-Signature Co-Chair http://www.w3.org/Signature/ W3C XML Encryption Chair http://www.w3.org/Encryption/2001/
