Smartphone security may recognise your fist bump

You may soon be able to fist bump, or use other body parts, to unlock your phone. Yahoo showcased Bodyprint, which will work with any touchscreen handset.

If typing a four digit code to unlock your phone is too much hassle, or your smartphone doesn’t have a fingerprint sensor, you may soon have more options. Yahoo has developed a way to unlock your phone using body parts such as your ear, palm, fingers, or knuckles.Bodyprint can turn any regular touchscreen into a biometric scanner. This is then used to recognise the unique shape of a user's body part and unlock your device.The technology was shown off at the 2015 Computer-Human Interaction Conference (CHI) in Seoul. A Bodyprint user unlocked his phone by pressing it to his ear; the process took less than a second. As you can see in the demonstration video, it’s also possible to fist bump your phone, or scan your fingerprints or palm.
