New patents are issued by the USPTO on Tuesdays. Today's Spotlight Patents continue the theme of blockchains (distributed ledgers, smart contracts) and rights management broadly construed. Assigned to Beatdapp (CA), the first of today's patent addresses techniques for scalably tracking media playback using blockchain. Assigned to IBM, the second patent addresses techniques for user authentication using a cryptographically secured register.
10,645,180, "System and method for scalably tracking media playback using blockchain," assigned to Beatdapp Software Inc. (CA).
Systems and methods for tracking media file playback are provided. A request to upload a media file and metadata associated with the media file is received. Next, the media file and metadata is uploaded via a blockchain protocol. Next, a request to play the media file is received from a client device or a digital service provider (DSP) platform. The request to play the media file is validated via the blockchain protocol. Upon validating the request to play the media file, the media file is transmitted for playback at the client device or DSP platform. Last, the number of times the media file is played is tracked via the blockchain protocol.
10,628,566, "Authentication using delegated identities," assigned to IBM.
The invention relates to a computer-implemented method for user authentication using a cryptographically secured register. An authentication request for authenticating the user is received. The user is authenticated using a root identity of the user. A successful authentication requires receiving a credential assigned to a root identifier of the root identity of the user. An authentication context of the requested authentication is identified. One of the one or more delegated identities assigned to the root identity of the user and assigned to the identified authentication context is identified. In response to a successful authentication of the user, an authentication token is issued confirming the successful user authentication and identifying the successfully authenticated user by the delegated identifier of the identified delegated identity.
