Researchers at the State University of New York at Buffalo (UB) have developed a three-dimensional (3D) biometric authentication methodology based on finger veins that they say can improve the security of this type of authentication.

The protocol utilizes photoacoustic tomography, in which laser light directed onto the subject's finger generates a sound when it encounters a vein; an ultrasound detector captures the sound, and uses all the sounds generated to create a 3D image of the finger's veins.

Testing found the technique can correctly accept or reject an identity 99% of the time.

UB's Jun Xia said, "Since no two people have exactly the same 3D vein pattern, faking a vein biometric authentication would require creating an exact 3D replica of a person's finger veins, which is basically not possible."
