A new finger vein authentication
called "mofiria" from Sony for laptops and phones
Sony has developed a new finger vein authentication technology
called "mofiria." Compact sized Mofiria is accurate
and responds quickly. This can be mounted on mobile devices
such as a personal computer, laptops and mobile phones.
With the increase of networked products and services, a
user-friendly interface for personal authentication and
higher security of personal information is in great demand.
Compared to the other biometric authentication techniques,
vein authentication technology achieves higher accuracy
on personal identification and forgery resistance because
it uses the veins inside the human body. Finger vein patterns
differ from person to person, each finger to finger, and
it is said that they do not change over the years.
"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 realized 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 commercializing this
technology within the 2009 fiscal year.
