US Patent 10498541 Electronic identification verification methods and systems

Method of certification including receiving user data at a certification device of a certifying entity, and receiving a registration tx-ID of the data, wherein the registration tx-ID was generated from a blockchain when receiving and storing a signed hash value of the data for registration signed using a private key of the user, wherein the hash value of the data was generated using a registration hash algorithm. The method includes generating a salt that is unique. The method includes hashing the data combined with the salt to create generated hashed data. The method includes signing the generated hashed data using a private key of the certifying entity to create a signed certification of the data. The method includes transmitting the signed certification of the data to a blockchain for storing. The method includes receiving a certification tx-ID of the signed certification of the data.
