New patents are issued by the USPTO on Tuesdays. Both of today's Spotlight Patents concern aspects of digital rights management. Assigned to Intel, the first patent addresses technologies for digital rights management of 3D printable models. Assigned to Broadcom, the second patent addresses techniques for social media video encoding.
9,558,330, "Technologies for digital rights management of 3D printable models," assigned to Intel.
Technologies for 3D printing digital rights management (DRM) include a 3D printing device communicatively coupled with a 3D model storage server and a rights management server over a network. The 3D printing device may establish a model unlock engine in a first trusted execution environment and a key release engine in a second trusted execution environment. The model unlock engine may extract a content access policy and a content key from an encrypted 3D model and generate a content key request to the key release engine. The key release engine may validate the content key request and decrypt the content key in response to the content access policy being satisfied. The model unlock engine may further decrypt 3D model content included in the 3D model using the decrypted content key to facilitate the printing of the 3D model.
9,560,366, "Video encoding for social media," assigned to Broadcom.
In some aspects, the disclosure is directed to methods and systems for encoding and sharing media clips via a social networking provider responsive to a user interaction via a single "like" or "share" button. Media may be constantly buffered as the user watches the program, such that the user need not initiate recording, enabling the user to quickly share amusing or media clips as they happen live. The device may decode, scale or subsample, and compress or re-encode the media to take up less space in a buffer of the device and/or to comply with copyright fair use requirements. Responsive to the user interaction or "share" command, the device may transfer the contents of the buffer to a social media service along with instructions to generate a post to the social network identifying the user, media, and/or buffer contents.
