US Patent 11681787 Ownership validation for cryptographic asset contracts using irreversibly transformed identity tokens

A method can include receiving identity data from a computing device. The method can include verifying that the identity data is associated with a live subject. The method can include generating a privacy-secured token based on the identity data. The method can include generating a randomized unique user identifier (RUUI). The method can include storing the privacy-secured token and the RUUI in association at a first registry. The method can include transmitting the RUUI to the computing device. The method can include configuring metadata of a cryptographic asset to include the RUUI. The cryptographic asset may be associated with a second registry, and the second registry may be associated with a blockchain environment.
