New pending patent applications are published on Thursdays. Both of this week's Spotlight Applications concern aspects of digital rights management. Assigned to Intellectual Discovery (KR), the first applications discloses methods for providing a license corresponding to encrypted contents to client apparatus and digital rights management conversion system using the methods. Assigned to Schneider Electric Industries (FR), the second application discloses techniques for authentication and authorization in an industrial control system using a single digital certificate.
20160134598, "Method for providing license corresponding to encrypted contents to client apparatus and digital rights management conversion system using the method," assigned to Intellectual Discovery (KR).
Abstract
Disclosed are a method for providing a license corresponding to encrypted contents to a client apparatus, which provides a license in response to a request of the license corresponding to contents super-distributed to a third person in a DRM conversion system, and a DRM conversion system using the same. First digital rights contents type first contents and a first license corresponding to the first contents are digital rights management converted to generate second digital rights contents type second contents and a second license corresponding to the second contents. A license request corresponding to the second contents super-distributed to a third person is received. A second license corresponding to the second contents super-distributed is requested from a server corresponding to the second digital right management. The second license corresponding to the second contents super-distributed is received and transmitted to the third person.
20160112406, "Authentication and authorization in an industrial control system using a single digital certificate," assigned to Schneider Electric Industries (FR)
Abstract
Systems and methods for performing access control in an industrial control system are described. A first component of an industrial control system may be connected to a second component of the industrial control system. A digital certificate may be generated for the first component that includes both authentication information and authorization information associated with the first component. The first component may transmit the digital certificate to the second component, and the second component may extract the authorization information from the digital certificate. The second component may identify a set of access rights based on the authorization information extracted and authorize the first component to access the second component based on the set of access rights identified.
