Webcam technology has remarkably changed its limit. One of its uses was to recognize a certain code for an augmented reality program. Now, it can also used to recognize a face. Lockface, is such an USB device which works better than a biometric scanner and can be stuck into any USB port. This device uses your face to make sure you are the right user, rather than a fingerprint.
Lockface is designed to work without using any separate software and starts by taking number of pictures of the user. It then uses these data to verify the user when he or she logs in. This tech scans correctly 98% of the time, but can verify the wrong person 1.91% of the time or simply won’t recognize the right user. But, if ever that happens there is a passcode to verify you’re the right user. This technology is already out in japan distributed by Futen in 4GB version which costs about $110.
