Manufacturers are exploring the world of biometrics and digital scanners put in almost everything – from photocopiers to school buses. And now a Yahoo research team may have found a way to extend the biometric recognition for anything with touchscreen.
To identify the protrusions and depressions that form the fingerprint, you need a high resolution scanner – something that is definitely not a touchscreen. But the researchers found, you can “grab” the principle of fingerprint and apply it to much larger parts of the body, which have a much more defined topology.
In practice, this means pressing the your ears or knuckles against the cellphone screen. Capacitive sensors on the screen are able to map the part of your body, check if it is your ear being pressed against the screen, and then unlock the device. The team says that in his limited study of 12 participants achieved an accuracy of 99.52%.
The system still needs to be tested on a wider scale until one can really say it’s safe – maybe three in 100 people have the joints of equal fingers pop them all the time. But if it works, the recognition of the body printing can be an inexpensive and effective way to ensure security for all smartphones
