Abstract
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.
Claims16
A method of providing attestation of personal identification information of a user by an attestor, comprising:
- receiving, by a first device, personal identification information of a user and a public key generated for the information;
- generating, by the first device, a first attestation address within a centralized or distributed ledger from the personal identification information of the user and the public key by:
- applying, by the first device, a first hash function to the personal identification information of the user to create a first hash result,
- combining, by the first device, the first hash result with the public key to generate a first public attest key, and
- combining, by the first device, at least one additional public key of a third party with the first public attest key to generate the first attestation address within the centralized or distributed ledger;
- and
- communicating, by the first device via a network to a second device maintaining the centralized or distributed ledger, a transaction comprising a first non-zero value for storage at the first attestation address, the presence of the first non-zero value associated with the first attestation address within the centralized or distributed ledger indicating that the personal identification information of the user is valid.

- receiving, by the first device, revised personal identification information of the user;
- responsive to receipt of the revised personal identification information of the user, generating, by the first device, a second attestation address within the centralized or distributed ledger from the revised personal information of the user and the public key;
- and
- communicating, by the first device, a second transaction transferring a second non-zero value to the second attestation address.

A system for providing attestation of personal identification information of a user by an attestor, comprising:
- a first device comprising a network interface in communication with a second device maintaining a centralized or distributed ledger, and processor circuitry;
- wherein the processor circuitry is configured to:
- receive personal identification information of a user and a public key generated for the information,
- generate a first attestation address within the centralized or distributed ledger from the personal identification information of the user and the public key by:
- applying a first hash function to the personal identification information of the user to create a first hash result,
- combining the first hash result with the public key to generate a first public attest key, and
- combining at least one additional public key of a third party with the first public attest key to generate the first attestation address within the centralized or distributed ledger;
- and
- communicate, via the network interface to the second device maintaining the centralized or distributed ledger, a transaction comprising a first non-zero value to the centralized or distributed ledger for storage at the first attestation address, the presence of the first non-zero value associated with the first attestation address within the centralized or distributed ledger indicating that the personal identification information of the user is valid.
