METHOD TO VERIFY AND IDENTIFY BLOCKCHAIN WITH USER QUESTION DATA

NºPublicación: US2019311102A1 10/10/2019

Solicitante:
FACETEC INC [US]

Resumen de: US2019311102A1

Systems and methods for enrolling and authenticating a user in an authentication system via a camera of a computing device include capturing and storing biometric information from at least one first image and at least one second image of the user taken via the camera. Prior to use, the user answers personal questions and the answers are stored as stored answer data. Later, such as at a business, the questions are presented to the user and the user provides their personal answers via a computing device. The answers are processed and uploaded to an authentication server where a comparison occurs against the stored answer data. If a match does not occur, then the authentication/identity verification processes ends. If a match does occur, then the authentication process continues. The questions match may serve as a gate function for accessing authentication data stored in a blockchain.
