"Your Fingerprints Can Be Recreated From the Sounds Made When You Swipe on a Touchscreen — Chinese and US Researchers Show New Side Channel Can Reproduce Fingerprints to Enable Attacks"

A team of researchers from China and the US have discovered a new potential attack on biometric security. Their paper titled "PrintListener: Uncovering the Vulnerability of Fingerprint Authentication via the Finger Friction Sound" describes a side-channel attack on the Automatic Fingerprint Identification System (AFIS). The attack exploits the sound characteristics of a user's finger swiping on a touchscreen to pull fingerprint pattern details. The researchers say they can successfully attack up to 27.9 percent of partial fingerprints and 9.3 percent of complete fingerprints in five attempts at the highest security False Acceptance Rate (FAR) setting of 0.01 percent. This article continues to discuss the PrintListener attack.
