Finger vein recognition is a biometric authentication method that utilizes pattern recognition techniques based on human finger vein patterns beneath the surface of the skin. Recognition of the finger vein is one of many forms of biometrics used to identify individuals and verify their identity.
Finger Vein ID is a biometric authentication system that matches the vascular pattern on an individual's finger with previously obtained data. Hitachi developed and patented a finger vein ID system in 2005. The technology is currently in use or developed for a wide variety of applications, including credit card authentication, automobile safety, attendance tracking and employee time, authentication Of computers and networks, ATMs.
To obtain the database registration pattern, an individual inserts a finger into a clogging terminal containing a near-infrared LED (light-emitting diode) light and a monochrome CCD camera (coupled charging device). Hemoglobin in the blood absorbs the near infrared LED light, which causes the vein system to appear as a dark line pattern. The camera records the image and the raw data is digitized, certified and sent to a database of recorded images. For authentication purposes, the finger is scanned as before and the data is sent to the registered image database for comparison. The authentication process takes less than two seconds.
Blood vessel patterns are unique to each individual, as are other biometric data such as fingerprints or iris patterns. Unlike some biometric systems, blood vessel patterns are almost impossible to fake because they are found beneath the surface of the skin. Fingerprint-based biometric systems can be fooled with a dummy finger equipped with a copied fingerprint; Voice and facial-based systems can be fooled by recordings and high-resolution images. The finger vein ID system is much harder to fool because it can only authenticate the finger of a living person.
