Tuesdays the PTO issues new patents. Both of today's Spotlight Patents deal with aspects of digital rights management. Assigned to Intertrust, the first patent concerns trusted and secure techniques for item delivery and execution. Assigned to Seagate, the second patent concerns techniques for anchor-point based digital rights management that provides for a posted move of one or more digital rights between two devices.
8,528,097, "Trusted and secure techniques for item delivery and execution," assigned to Intertrust.
Documents and other items can be delivered electronically from sender to recipient with a level of trustedness approaching or exceeding that provided by a personal document courier. A trusted electronic go-between can validate, witness and/or archive transactions while, in some cases, actively participating in or directing the transaction. Printed or imaged documents can be marked using handwritten signature images, seal images, electronic fingerprinting, watermarking, and/or steganography. Electronic commercial transactions and transmissions take place in a reliable, "trusted" virtual distribution environment that provides significant efficiency and cost savings benefits to users in addition to providing an extremely high degree of confidence and trustedness. The systems and techniques have many uses including but not limited to secure document delivery, execution of legal documents, and electronic data interchange (EDI).
8,522,360, "Posted move in anchor point-based digital rights management," assigned to Seagate.
An anchor-point based digital rights management provides for a posted move of one or more digital rights between two devices. By executing a posted move, a user (1) disables a binding record of a source user device, thereby terminating authorized use of the digital property instance through at the source anchor point; and (2) enables a different binding record of a target user device, thereby allowing authorized use of the digital property instance through that target anchor point. Such a "move" can accomplished through secure communications links mediated by one or both of a content handler and an anchor point message system.
