New patents are issued by the USPTO on Tuesdays. Today's Spotlight Patents continue the theme of blockchains (smart contracts, distributed ledgers) and rights management broadly construed. Assigned to Eluvio, the first patent addresses techniques for a decentralized system for secure access of digital content. Assigned to AT&T, the second patent addresses techniques for scalable and secure content delivery.
10,805,084, "Decentralized system for secure access of digital content," assigned to Eluvio, Inc.
Disclosed are examples of decentralized systems and related apparatus, devices, computer program products, and methods for secure access of digital content. In some implementations, a first request from a client to access encrypted digital content includes a call on a digital contract. The call passes an ephemeral key set encrypted with a public key of a consumer. A transaction identifying the first request in association with the encrypted ephemeral key set is recorded in the digital contract. The transaction is identified by a transaction identifier (ID), which is sent to the client. A second request from the client includes: an authorization token including the transaction ID, and a signature of the consumer. Authorization of the consumer is verified based on the authorization token. A transaction identifying one or more keys is recorded in the digital contract. The digital content can be re-encrypted and sent to the client.
10,803,025, "System and process for scalable and secure content delivery," assigned to ATT.
Aspects of the subject disclosure may include, for example, segmenting a file to obtain a set of segments, wherein the file can be regenerated according to a recombination of the set of segments. At least some segments are transported to a targeted group of users including a first group of users and a second group of users, via unlicensed frequency spectrum and according to a peer-to-peer file sharing process. A segmentation record identifying the set of segments is provided to the targeted group of users. A progress of a delivery of the set of segments is monitored according to the segmentation record. The progress of the delivery is analyzed to identify a deficiency in delivery of a particular segment of the set of segments. Responsive to the deficiency, the particular segment is provided to the first group of users via a licensed frequency spectrum. Other embodiments are disclosed.
