The identifying principle of the Finger vein identification unlocking system is according to the characteristic of infrared absorption of flowing blood in fingers. The system will obtain the finger vein image by near-infrared photography and use the specific algorithm to do the comparison and feature extraction to the imagines so that car can identify the identity. On the fundamental of increasing safety, the finger vein identification unlocking system will not be affected by the natural light and it is still functioned whether the surface of fingers is folded, rough, wet, and dirty or not. Blood vessels are hiding in the finger so the finger vein identification unlocking system is truly the living body recognition and it is much more intelligent, more convenient, and safer. This system makes zero security risk come true due to the living body feature is hardly able to copy and it is very tricky to break its technique so it is unbreakable.
