Methods and apparatus for providing authentication of information of a user are described. Upon validation of this information, a first hash function is applied to the user's information to create a hash. A public attest key is generated by combining the hash of the user's information with one or more public keys. An attestation address is generated based on the public attest key. A signed transaction which includes the attest key is communicated for storage in a centralized or distributed ledger at the attestation address.
