Researchers Develop Master Fingerprints That Can Break Into Smartphones (digitaltrends.com)

Researchers at New York University and Michigan State University have recently found that the fingerprint sensor on your phone is not as safe as you think. "The team has developed a set of fake fingerprints that are digital composites of common features found in many people's fingerprints," reports Digital Trends. "Through computer simulations, they were able to achieve matches 65 percent of the time, though they estimate the scheme would be less successful in real life, on an actual phone." From the report: Nasir Memon, a computer science and engineering professor at New York University, explained the value of the study to The New York Times. Modern smartphones, tablets, and other computing devices that utilize biometric authentication typically only take a snapshots of sections of a user's finger, to compose a model of one fingerprint. But the chances of faking your way into someone else's phone are much higher if there are multiple fingerprints recorded on that device. "It's as if you have 30 passwords and the attacker only has to match one," Memon said. The professor, who was one of three authors on the study, theorized that if it were possible to create a glove with five different composite fingerprints, the attacker would likely be successful with about half of their attempts. For the record, Apple reported to the Times that the chance of a false match through the iPhone's TouchID system is 1 in 50,000 with only one fingerprint recorded.

      Would you be happy with a car that someone could start from a 'master key' 65% of the time? What about 33%, half that? Would you be fine with 10%?

      The fact that a small set of fake fingerprints can unlock a third or more of all phones in the real world is a disaster for the pretense of using fingerprints as a security measure. It's not much ado about nothing - it's much ado about everything you are trying to protect.

      Depends a lot on the configuration: if the system is using fingerprints to differentiate, say, 1000 employees from potentially millions of outsiders - and to identify yuh among that 1000, then it will be configured very differently than if you enter your identity and the system only needs to decide if the fingerprint matches the one on file for that specific identity
