Biometrics is significant mean for personal identification because it uses features of the human body which have less possibility to be lent or stolen. Using venuos pattern in a finger acquired from near infrared image has advantages to other biometric personal identification because it refers to the features inside the human body and the device for imaging would be small.A simple device to acquire a venous patten inside a finger was setted up using a small halogen light for a portable light and a monochrome CCD camera with infrared filter. Venous patterns were tried to be extracted by repeated local line tracking method for binalized images. Identification test with use of pattern matching was performed but it did not show enough result.Unclear venous images are guessed to cause these poor results. If appropriate light sources are deviced to be installed, this system would be effective because extracted venous pattern partly shows good correspondences to some portion of the visually extracted venous pattern.
