As a result, a successful fingerprint brute-force attack requires only that an inputted image provides an acceptable approximation of an image in the … Read More “Brute-Forcing a Fingerprint Reader” »

Researchers are able to create fake fingerprints that result in a 20% false-positive rate. The problem is that these sensors obtain only partial images of users’ fingerprints — at the points where they make contact with the scanner. The paper noted that since partial prints are not as distinctive as complete prints, the chances of … Read More “Using Machine Learning to Create Fake Fingerprints” »
