Biometric devices (such as fingerprint sensors, iris scanners, face recognition systems etc.) are becoming more and more popular in areas where personal identification is required - migration control, physical access, online banking etc. Nowadays the most used biometric sensor is a fingerprint scanner which provides a good combination of accuracy, size and price. However, fingerprint recognition is not always successful in case of sweaty/dirty fingers and the accuracy rate can fall down to 80-90% which is not enough for high-security applications. The solution of this problem can be found in combining fingerprint pattern with other biometric data inside the finger (vein pattern or bone geometry). It can be ach
