On Thursdays the USPTO publishes new pending patent applications. Both of today's Spotlight Applications concern aspects of digital rights management. Assigned to Tata Consultancy Services (IN), the first application discloses techniques for enterprise digital rights management. Assigned to Huawei Technologies (CN), the second application discloses technques for making system constraints of a specified permission in digital rights management.
20130024948, "System for enterprise digital rights management," assigned to Tata Consultancy Services Limited (IN)
The present subject matter relates to devices and methods for enterprise digital rights management. In one implementation, a device includes a security module configured to generate a security key. The security module encrypts at least one document of a user, using the security key, to generate a protected document. Further, the device includes an access control module configured to assign an access right to one or more users within an enterprise for accessing the protected document. The access control module is further configured to delegate the access right from the user to another user. The access control module is furthermore configured to lock at least one of the user and the protected document.
20130024945, "Making system constraints of a specified permission in digital rights management," assigned to Huawei Technologies CO., LTD. (CN).
A method and a terminal device for making multi-system constraint of a specified permission in a digital rights. A rights object related to content object is obtained by an executing device. The specific permission descriptions of the rights object include system constraint descriptions of a plurality of systems of the same type. The executing device obtains a corresponding system information in the device according to the system constraint descriptions and compares the system information in the device with the system information in the system constraint descriptions, so as to judge whether there is any system permitted in system constraint descriptions. If yes, it determines to permit executing the specific permission for the content object; otherwise, it determines not to permit executing said specific permission for the content object.
