Vein authentication reads the invisible pattern of veins in the palm or finger. Of all the existing biometric approaches, palm vein authentication and finger vein authentication systems are highly accurate and resistant to misconduct such as forgery and impersonation. In recent years, biometric authentication, which can accurately identify individuals based on their biological characteristics, has grown in popularity as a means of personal identification for biometric physical security and biometric access control applications.

Palm Vein Authentication - Biometric Security & Access ControlContactless Vein authentication biometric technology has been highly-appraised for its ease-of-use and assurance that it has given users through its robust security. It has been widely adopted as a means of personal identification at financial institutions, and as a computer login and room entrance control method at corporations.

As veins are internal in the body and have a wealth of differentiating features, attempts to forge an identity are extremely difficult, thereby enabling a high level of security. Additionally, the sensor of the palm vein device can only recognize the pattern if the deoxidized hemoglobin is actively flowing within the individual’s veins.

Compared to finger veins, palm veins are more numerous and create complex patterns, resulting in a higher volume of data. Consequently, the system’s recognition accuracy is extremely high, with a false-negatives rate of 0.01% and a false-positives rate of 0.00008%. Furthermore, the fact that the system uses an individual’s thicker veins allows for stable operations over time. Lastly, the system is contact-free, helping to reduce any existing psychological burdens placed on users.
