When the word biometric is used, most people associate it with fingerprint scanning. While this is the most popular biometric technique, there are many others too. One of the new and highly secure technique is palm vein recognition. This new technique is still not popular, but its benefits ensure it will soon be widely used observed Bahaa Abdul Hadi.

What is palm vein recognition?

Fingerprints, iris pattern, and facial patterns are used in biometrics because they are unique to each individual. In the same way, the veins on the palm have been found to be unique for each person. Scanners can read palm vein patterns and use it to identify and authenticate people.

How does palm vein recognition work?

The veins on a person’s palm form a unique pattern that is not duplicated in any other individual. In palm vein recognition, a scanner reads the plan and creates a pattern based on the vein arrangement. This pattern is then stored. Whenever a person places the palm on the scanner, the vein pattern is read and compared with the database. This is used to identify and authenticate people.

The human body has hemoglobin that moves oxygen. Deoxygenated blood is moved to the heart through the veins. The hemoglobin present in the veins is thus deoxygenated. When the palm scanner sends infrared light, the hemoglobin absorbs the light. The veins then appear as a black pattern that can be saved and used for comparison.

To ensure security, this pattern is not stored as it is. It is encrypted, so even if someone gains access to the database they will not be able to use the pattern. Studies have shown that palm vein recognition has a false acceptance rate of just 0.000008% and a false rejection rate of 0.01%. This clearly shows it is a highly secure and reliable biometric technique.

Benefits of palm vein recognition

  • Palm vein recognition is a biometric technique that can be used to identify people and authenticate them. It is a more accurate system than fingerprints and face scans.
  • Privacy of individuals is ensured since palm vein patterns cannot be scanned without a person knowing.
  • Palm vein scanners are robust and the palm vein patterns do not change. This ensures it is a reliable biometric technique to use.
  • A very important benefit is that palm vein scanners do not require physical contact with the palm. It is a contactless technique and the scanner can scan the palm from a distance.
