U.S. Patent 10938579 was awarded on March 02, 2021 and is entitled “Radio frequency identification tag one-way authentication using a one-time password pad and a blockchain.” The first named inventor is Keir Finlow-Bates of Kangasala, . The abstract contains an overview of the patent disclosure:

A radio frequency identification device, or RFID tag, has an antenna attached to or formed on a microchip. The microchip usually comprises low power fixed or programmable logic and a small quantity of persistent memory. As many RFID tags are powered by radio waves transmitted from an RFID tag reader, the low power fixed or programmable logic is often not capable of performing complex cryptographic calculations required for digital signing to provide one-way authentication of the tag. In the present disclosure a system and method are presented for enabling a low overhead challenge and response using a one-time password pad comprising passwords on the RFID tag and a blockchain to record a use of the passwords. Methods are also disclosed for securely replacing the one-time password pad, and using the RFID tag in combination with a blockchain to provide provenance information for the RFID tag.
