Fingerprints Fall Short When It Comes to Securing Smartphones

A new study finds that smartphone fingerprint security has vulnerabilities similar to weak passwords.

Consumers can be pretty lax about their online security.

About 4% of the time, the password to unlock a smartphone is 1-2-3-4, says Nasir Memon, a professor of computer science and engineering at New York University Tandon School of Engineering. And that’s a pretty high probability for just guessing, he says.

To help make it easier for consumers to protect data and personal information, many newer smartphones, such as the iPhone 6, can be locked with a fingerprint sensor, which is a form of biometric authentication. Other biometric identifiers include retina or facial features.
