10,930,144, "Systems and methods for collaborative road user safety," assigned to Labyrinth Research LLC.
Systems and techniques describe a collaborative road user safety service that interacts with a coordinating set of collaborative safety devices belonging to road users in order to interchange reliable information about road safety. A distributed ledger/blockchain is utilized in connection with the service to coordinate data exchange between collaborative safety device users and provide data subscribers with reliable safety data that can be used to automate ancillary technical processes. Collaborative safety devices can alert members to road safety issues and be used to confirm information about road safety by collecting sensor and telemetry data. Data subscribers can receive aggregated, anonymized, de-anonymized, or specific road user data pertaining to road users and define the terms of incentives to road users that "self-revise" if a road user's vehicle is a target vehicle via smart contract interfaces. Cryptographic token can be transferred to incentivize data sharing, accuracy, and safe road behaviors.
10,931,457, "Systems and methods for blockchain-based digital lottery ticket generation and distribution," assigned to IGT Global Solutions Corporation.
A method of generating a digital lottery ticket includes receiving a transaction record associated with a ticket issuance request from a computing device, wherein the transaction record includes transaction data including a player entry and a first public key associated with the player entry, generating a first message including digital ticket information, TKD, relating to the player entry, a source field and a destination field, generating a digital signature of the first message using a private key of an issuer server, transmitting the first message and the digital signature to a transaction certification authority (TCA) server for storage on a publicly viewable transaction ledger maintained by the TCA, receiving from the TCA server a second message including a digital ticket number and a transaction ID associated with the first message and the digital ticket number, and transmitting a third message including the transaction ID and the digital ticket number to the computing device.
