FAKE-FINGER DETERMINATION DEVICE, FAKE-FINGER DETERMINATION METHOD AND FAKE-FINGER DETERMINATION PROGRAM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18351236 titled 'FAKE-FINGER DETERMINATION DEVICE, FAKE-FINGER DETERMINATION METHOD AND FAKE-FINGER DETERMINATION PROGRAM
Simplified Explanation
- The patent application describes a device that can determine if a fake finger is being used for fingerprint authentication. - The device includes an imaging unit that captures the fingerprint image, a classifying unit that analyzes the image and classifies different regions, and a determining unit that determines if a foreign substance is present near the finger. - The device uses a transparent thin film attached to the finger surface to help discriminate fake fingers. - The imaging unit captures the fingerprint image for authentication purposes. - The classifying unit analyzes the captured image and divides it into different regions, such as the skin region and the background region, based on the colors of the pixels in the image. - The determining unit then examines the regions classified by the classifying unit and determines if a foreign substance is present in the area around the finger. - This technology can help prevent fraudulent use of fake fingers for fingerprint authentication.
Original Abstract Submitted
A fake finger in which a transparent thin film is attached to a finger surface is discriminated. A fake-finger determination device includes: an imaging unit that captures an authentication object as a fingerprint authentication object; a classifying unit that classifies an image captured by the imaging unit into a plurality of regions including at least a skin region and a background region using colors of pixels included in the image; and a determining unit that determines whether or not a foreign substance is present in the periphery of a finger based on a feature of a region classified as neither the skin region nor the background region out of the regions classified by the classifying unit
