Secure, decentralized, automated platform and multi-actors for object identity management through the use of a block chain technology

Abstract

Secure management of keys and identities of an object manufactured by a manufacturer having a manufacturer key pair, and a client having a client key pair, the management being carried out using a decentralized blockchain database. The method includes generation of a manufacturing key pair; and publication and recording, in the blockchain, of the decentralized object identifier used to obtain the public key of the object. When a client purchases the object from the manufacturer, the method includes providing, by the object manufacturer, the object identifier, and the public manufacturing key to the client; and updating the blockchain. When the object is switched on for the first time, the object enrolls itself by generation of a utilization key pair; auto-enrollment using the manufacturing key pair; and replacement, in the blockchain, of the public manufacturing key associated with the object identifier with the public utilization key associated with the object identifier.
