Sony has announced “mofiria,” a biometric technology that relies on the unique vein pattern in fingers to authenticate users. Apparently, this method is more accurate than traditional fingerprint techniques.
“mofiria” uses a unique method where a CMOS sensor diagonally captures scattered light inside the finger veins, making a plane layout possible. As a result, a small and more flexible design can be realised in building this technology into mobile devices.
The vein pattern is extracted from the captured finger vein image, and data from the pattern is compressed into the size of one-tenth to store in memory, which makes it possible for the data to be stored on a mobile device. Sony’s unique algorithm achieves fast and easy operation. The vein pattern is quickly and accurately extracted from the captured finger vein image without a fixed finger position, as the position of a placed finger is automatically and simultaneously corrected. As a result, the authentication accuracy is less than 0.1% for the FRR (False Rejection Rate), less than 0.0001% for the FAR (False Acceptance Rate), and processing time for identification takes only about 0.015 sec*1 using a personal computer CPU and about 0.25 sec*2 when using a mobile phone CPU.
Sony plans to promote the “mofiria” technology for use in mobile devices, gateway security systems and solution services. Sony will aim for commercialising this technology within the 2009 fiscal year.
