Patent number: 11917084Abstract: Described herein is a system and method for validating media integrity using asymmetric key cryptography utilizing a public/private cryptographic key pair. The private key is kept secret and is known to an originator and/or publisher of a media file. The public key is added to the media file and is used to validate integrity of the media file, that is, that content of the media file (e.g., portion(s), frame(s)) has not been altered since publication of the media file. By validating integrity of the media file, strong proof that the media file came from an owner of the keypair (e.g., had possession of the private key) can be obtained, for example, resolving issues of trust and/or authenticity common in altered content. In some embodiments, information regarding an origin of the content can further be determined.Type: GrantFiled: August 8, 2022Date of Patent: February 27, 2024Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Rebecca Nicole Burke-Aguero, Samuel John Wenker, Andrew Lee Jenks, Isha Sharma

Patent number: 9590952Abstract: Lossy data stream decoder techniques are described herein. In response to a request for decoded content from a consuming application, a decoder may validate headers and identify portions of the data that are considered pertinent to the request. The decoder then performs lossy extraction to form incomplete data that is provided to the consuming application in response to the request. The full data for the data stream is not exposed to the consuming application or other downstream components. In this way, the consuming application is provided data sufficient to perform requested graphics processing and resource management operations, while at the same time the risk of piracy is mitigated since the consuming application is unable to get a full version of the data in the clear and the data have been validated by the decoder.Type: GrantFiled: September 5, 2014Date of Patent: March 7, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Yongjun Wu, Fedir Yuriyovych Kyslov, Shyam Sadhwani, Samuel John Wenker, Brian P.
