20130219512, "Apparatuses and methods for processing file content using digital rights management (DRM) in web browser," assigned to ConDel International Technologies Inc.
An electronic device for processing file content using Digital Rights Management (DRM) is provided with a DRM agent, a plug-in, and a web browser. The DRM agent module processes DRM-protected content associated with an electronic file. The plug-in enables access of electronic file. The web browser includes a module which is to be invoked during loading of the DRM-protected content associated with electronic file and is installed with the DRM agent. Upon receiving a request for electronic file, the module determines whether electronic file is DRM protected. After determining that electronic file is DRM protected, the module activates the processing of the DRM-protected content by the DRM agent to obtain electronic file portion-by-portion such that the web browser directly accesses or uses a corresponding native player or a corresponding plug-in of the web browser to access electronic file with obtained portions, respectively.
20130219451, "Document digest allowing selective changes to a document," apparently assigned to Adobe.
Methods and apparatus, including computer program products, implementing and using techniques for digital rights management. A set of content items is defined in an electronic document based on a set of rules. The rules in the set of rules are associated with one or more operations that can be performed on content items in the electronic document. The set of content items include only content items that are invariant to the operations associated with the rules in the set of rules. A representation of the content items in the set of content items is generated. An electronic document is also described.
