Every Thursday the USPTO publishes patent applications, and Thanksgiving was no exception. Assigned to DirecTV, the first application discloses techniques for secure content transfers. Assigned to Intertrust, the second is another divisional (same specification, different claims) of "Trusted and Secure Techniques for Item Delivery and Execution".
20070265978, "Secure content transfer systems and methods to operate the same," assigned to DirecTV.
Secure content transfer systems and methods to operate the same are disclosed. An example system includes a content server to encrypt content according to an encryption key, and to transfer the encrypted content, the encryption key and a license to a client that supports a digital rights management technology. The example system further includes a broadcast system headend to determine the encryption key, wherein the broadcast system headend is physically separate from the content server, and a digital rights management license server to provide the license.
20070271463, "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).
