New patents are issued by the USPTO on Tuesdays. Both of today's Spotlight Patents continue our theme of blockchains (smart contracts, distributed ledgers) and rights management broadly construed. Assigned to Beatdapp, the first of today's patents addresses techniques for continuous tracking of media playback using blockchain. Assigned to Advanced New Technologies (KY), the second patent addresses techniques for blockchain-based copyright protection.
10,893,112, "System and method for continuous tracking of media playback using blockchain," assigned to Beatdapp Software, Inc. (CA)
Systems and methods for continuous tracking of media file playback. First, transaction data from a platform stream is received. The transaction data corresponds to a request to play a media file from an end user, as well as continuous play information. Next, the transaction data is verified. Then, the verified transaction data is signed using a cryptographic signature. Next, it is determined whether the transaction data corresponds to a valid blockchain transaction. If the transaction data corresponds to a valid blockchain transaction, the valid blockchain transaction is recorded to a blockchain. Last, the transaction data and the cryptographic signature are transmitted to one or more validation nodes.
10,904,251, "Blockchain-based copyright protection method and apparatus, and electronic device," assigned to Advanced New Technologies Co., Ltd. (KY)
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a blockchain-based right protection. One of the methods includes: sending, to a blockchain network, a request for verifying a right to access a digital product, the request comprising identity information associated with a target user; receiving, from the blockchain network, a response comprising a result of verifying the right to access the digital product based on the identity information associated with the target user; in response to the result being that the verifying the right to access the digital product is successful, determining identification information for tracing the target user; and embedding the identification information for tracing the target user in content associated with the digital product.
