Smart contracts, blockchains (distributed ledgers) and rights management broadly construed are the themes of this week's Spotlight Applications. Assigned to Hella GmbH (DE), the first application discloses techniques for decentralized digital authentication. Assigned to Here Global (NL), the second application discloses techniques for providing a consent management system on a crytographic ledger.

A method and system for digital authentication is disclosed, in which an owner device associated with a smart lock receives identity information of a user device requesting access to the smart lock. The owner device registers first contract information of the smart contract, for granting access of the smart lock to the user device, on a decentralized trust network, and sends second contract information about the smart contract to the user device. The second contract information comprises validation information of the smart contract indicating an un-validated information of the second contract information. The user device validates the received second contract information against the first contract information on the decentralized trust network, and authenticates the user device with the smart lock using the validated second contract information.

An approach is provided for a consent management using a cryptographic ledger (e.g., a blockchain). The approach, for example, involves providing a cryptographic ledger. The cryptographic ledger includes one or more data records that store metadata indicating a consent request from a data consumer to provide an access to data owned by a data subject, a consent response from the data subject to the consent request, or a combination thereof. The approach also comprises providing a neutral server to read the data from a database of a data provider on behalf of the data consumer based on the cryptographic ledger.
