Abstract
A method of controlling assignment and management of identities in ambient electromagnetic power harvesting (AEPH) chips. The method comprises allocating a plurality of unique AEPH identities by an AEPH management application executing on a computer system, receiving a plurality of requests by the AEPH management application to update a state associated in a blockchain with the unique AEPH identity identified in each request; determining by the AEPH management application that the blockchain is to be terminated; adding by the AEPH management application a terminal block to the blockchain; receiving a request by the AEPH management application to update a state associated with a unique AEPH identity in the blockchain; and sending a request rejection by the AEPH management application to the affiliated device that sent the request to update the state associated with the unique AEPH identity in the blockchain after the terminal block was added to the blockchain.
