Abstract
A method and system of providing verification of information of a user relating to an attestation transaction is provided, and includes sending a request for information of the user, wherein the information has been previously attested to in an attestation transaction stored within a centralized or distributed ledger at an attestation address; receiving at a processor associated with a verifier the information of the user; sending a cryptographic challenge nonce; receiving at the processor associated with the verifier the cryptographic challenge nonce signed by the user's private key; verifying user identity with the cryptographic challenge nonce signed by the user's private key; deriving a public attest key by using the information of the user; deriving an attestation address using the public attest key; and verifying the existence of the attestation transaction at the attestation address in the centralized or distributed ledger.
