New pending patent applications are published by the USPTO on Thursdays. Today's Spotlight Applications continue the theme of blockchain (distributed ledger, smart contracts) and digital rights management broadly construed. Assigned to Axoni, the first of today's applications discloses techniques for distributed privately subspaced blockchain data structures with secure access restriction management. Assigned to General Motors, the second application discloses techniques for using a blockchain database for data exchange between vehicles and entities.
20180349621, "Distributed privately subspaced blockchain data structures with secure access restriction management," assigned to Schvey, Inc. d/b/a/ Axoni.
Abstract
Disclosed herein is a system for providing a cryptographic platform for distributing data structures within a peer-to-peer network wherein encrypted messages are exchanged among nodes. The system provides for the creation and management of privately subspaced blockchains that include subspaces that are private, yet verifiable through the use of global state roots. The global state roots are updated based on subspace roots that are in term generated based on the data in that subspace.
20180342036, "Method and system using a blockchain database for data exchange between vehicles and entities," assigned to GM Global Technology Operations LLC.
Abstract
A method and system using blockchains for distributing event information related to vehicle operation between a plurality of entities. The method includes executing blockchain agreements between the plurality of entities participating in a blockchain exchange for distributing event information related to the vehicle operation, where the blockchain exchange includes a plurality of databases having blockchains of data blocks for storing the event information. Next, generating by a particular entity of the plurality of entities the event information related to vehicle operation and validating the event information by a consensus of the plurality of entities participating in the blockchain exchange. Then, appending, upon validating by the consensus, a blockchain within the blockchain database for enabling each entity to have access to a same replicated block data with the event information to enable enhanced vehicle operations of multiple vehicles based on the same replicated block data.
