Development of blood vessel identification systems and biometrics access control systems

Bionics’ blood vessel identification system identifies the patterns in blood vessels that are unique to each individual, then uses special image processing for authentication. Specially developed algorithms extract and match unique features, making it possible to uniquely identify people from the blood vessel patterns in a single finger. This technology is at the cutting edge of identification accuracy, extremely close to a hundred percent in correct identification.

The procedure begins with a light source such as an LED shined on the finger to make the blood vessels visible. Then a high-quality infrared CCD camera is used to take an image, from which the blood vessel patterns are extracted. Special image processing is then carried out including the use of a characteristic matching algorithm to authenticate the individual.

Features of the system include:

1. Blood vessel patterns are absolutely unique even between identical twins
2. Blood vessel pattern changes over time and due to age are compensated for by the system
3. Compared to other technologies, there is a lower level of concern about privacy issues
4. Biometric data is used, a form of data extremely difficult to imitate
5. The uniquely developed technology is not affected by cuts or dirt on the surface of the finger (to a certain degree)
6. The contact area of the finger and the device is small so that the sensor is not dirtied and improper authentication is low
7. The device is easy to use
