The new iPhone 5S’s fingerprint sensor has been cracked by a German group only days after an international group of donors gathered to offer a prize for the first conclusive proof that the new biometric scanner could be cracked. The crack was accomplished by the Chaos Computer Club, a group based in Germany. To beat the new lock, which uses fingerprint information to unlock the new iPhone and complete purchases through Apple’s App Store, was accomplished by taking a high resolution photograph of a fingerprint that someone had left on their iPhone. People, after all, leave thousands of fingerprints on their phones every day. “This demonstrates – again – that fingerprint biometrics is unsuitable as access control method and should be avoided,” the team wrote on their site. It is, after all, far easier to change a compromised password than it is to change a compromised fingerprint. And few people leave copies of their password all over their phone, keys, doorknobs, drinking glasses and countless other places. To crack Apple’s iPhone security, the team took a photo of a fingerprint at 2400 dots-per-square-inch. Then they laserprinted an image of the fingerprint on a transparent sheet using a “thick toner” setting. This raised the ink from the page slightly. When the ink dried, they covered it with a liquid latex, which dried around the fingerprint pattern. The team then lifted the latex from the sheet, breathed on it a bit to make it moist, and pressed it to the iPhone 5S fingerprint sensor. We hope that this finally puts to rest the illusions people have about fingerprint biometrics. It is plain stupid to use something that you can´t change and that you leave everywhere every day as a security token”, said Frank Rieger, spokesperson of the CCC on their website.
