Abstract

To tackle with false recognition of the forged vasculars in vein recognition, a new vascular recognition method is proposed by photoacoustic anti-counterfeiting. An optical-resolution photoacoustic microscopy imaging system is built by use of the laser diode. Then, photoacoustic experiments were performed on the forged vasculars and isolated subcutaneous vasculars. To realize anti-counterfeiting of vasculars, the photoacoustic signal intensity is used to distinguish between forged and real vasculars. Meanwhile, the vascular recognition performance can be lifted on our established photoacoustic vascular library. The experiment results show that the proposed technique has the advantages of high anti-counterfeiting and high recognition rate, and can be applied in biometrics.
