Research and development of a two-factors face authentication system using an invisible F-QR code on ID card by 1064 nm laser and AI camera

Abstract

The face authentication system using two security factors: an invisible F-QR (face QR) code printed on an ID card and face recognition using AI camera is presented in this paper. F-QR codes with facial features are generated by a chain processing of face detection, face property extraction and QR code generation. The F-QR code is printed on a plastic ID card using a 1064 nm fiber laser. The ID card is made of special materials, including a layer of filter material that allows the 1064 nm laser to pass through while blocking visible lights so that the printed F-QR code on the card is invisible to the human eye or conventional QR code readers. Face authentication is implemented using a dedicated invisible F-QR code reader combined with an AI camera to decide the Cosine similarity between two face feature vectors to make an accurate decision for the authentication.
