SYSTEM, DEVICE AND METHOD FOR FINGERPRINT AUTHENTICATION USING A WATERMARKED DIGITAL IMAGE

Abstract:

A system, device and method for fingerprint authentication using a watermarked digital image is provided. A device includes a display device including a touch screen configured to detect fingerprints; and, a controller. The controller: generates, at the display device, an image that includes, in one or more given areas, image-embedded fingerprint information; detects, at one or more portions of the touch screen respectively corresponding to the one or more given areas, user-fingerprint information representing a fingerprint; implements a comparison between the user-fingerprint information and the image-embedded fingerprint information; and when the comparison between the user-fingerprint information and the image-embedded fingerprint information is successful, implement an access process.
