Abstract
Blockchain-based device authentication by a user device to enable a second device is disclosed to perform an action on a first device on behalf of a user linked to the user device, based on a command received from the second device. Authentication includes the steps of: (i) obtaining an indentity information associated with an identity document of the user; (ii) storing the identity information, and a set of credentials, with a blockchain to link the identity information with the set of credentials for the user; (iii) signing a first trust certificate by a user private key on the blockchain to obtain a first signed trust certificate; and (iv) signing a second trust certificate by the user private key on the blockchain to obtain a second signed trust certificate.
