Hackers Make a Fake Hand to Beat Vein Authentication
Tuesday January 1, 2019. 06:30 AM , from Slashdot
Devices and security systems are increasingly using biometric authentication to let users in and keep hackers out, be that fingerprint sensors or perhaps the iPhone's FaceID. Another method is so-called 'vein authentication,' which, as the name implies, involves a computer scanning the shape, size, and position of a users' veins under the skin of their hand. But hackers have found a workaround for that, too.
From a report: On Thursday at the annual Chaos Communication Congress hacking conference in Leipzig, Germany, security researchers described how they created a fake hand out of wax to fool a vein sensor. 'It makes you feel uneasy that the process is praised as a high-security system and then you modify a camera, take some cheap materials and hack it,' Jan Krissler, who goes by the handle starbug, and who researched the vein authentication system along with Julian Albrecht, told Motherboard over email in German. Vein authentication works with systems that compare a user's placement of veins under their skin compared to a copy on record. According to a recent report from German news wire DPA, the BND, Germany's signals intelligence agency, uses vein authentication in its new headquarter building in Berlin.
One attraction of a vein based system over, say, a more traditional fingerprint system is that it may be typically harder for an attacker to learn how a user's veins are positioned under their skin, rather than lifting a fingerprint from a held object or high quality photograph, for example. But with that said, Krissler and Albrecht first took photos of their vein patterns. They used a converted SLR camera with the infrared filter removed; this allowed them to see the pattern of the veins under the skin.
