"3D Biometric Authentication Based on Finger Veins Almost Impossible to Fool"

Biometric authentication methods rely on unique biological characteristics for identity verification. These methods are continuing to replace traditional passwords. A team of researchers developed a new biometric authentication method that is based on 3D images of human finger vein patterns beneath the skin's surface. The technique has been shown to accurately accept or reject an identity 99% of the time. The researchers use photoacoustic tomography to achieve 3D biometric authentication. Photoacoustic tomography is an imaging technique in which light and sound are combined. This technique is used in the reconstruction of 3D finger vein images. This article continues to discuss the development and benefits of the 3D finger vein biometric authentication system.
