Vein identification, also known as vascular technology, it is a biometric identification approach that analyses the blood patterns visible on the skin’s surface. Despite the fact that it is used by FBI and CIA for community security and criminal investigations, such as forensic investigation and law enforcement, this recognition method is still in development. Vein recognition technology offers great solutions to challenges. Some challenges are ID or password leakage and then reusing it, lost smart cards or keys. Finger Vein Recognition can become most promising for high security applications. Our paper explains about the different cutting-edge machine learning algorithms that are applied so far. At the end, a comparative analysis is provided.
