Finger Vein Technology

Accurate and counterfeit-proof authentication
is achieved with Finger Vein Recognition

The finger vein authentication technology developed by ETUNNEL
is a new technology with excellent security, versatility,and immunity to hacking.

ETUNNEL has filed global patents (in the US, Japan, Europe, South Korea, etc.) and
is currently being used by the Ministry of Defense, government offices, and various companies.

When logging into a computer, using an ATM, or passing through certain areas,
passwords and fingerprints are commonly used as methods of identity verification.
However, several issues with these methods have been pointed out.

Finger vein authentication technology is a relatively new method in the field of biometric authentication.
It works by verifying whether the finger vein pattern of an individual matches pre-registered data.

With its excellent security, it is replacing traditional methods such as passwords and fingerprints,
and is emerging as the best alternative to prevent hacking and cybercrime.

How it works

Operating Principle

Near-Infrared (IR) Light Transmission

  • A near-infrared (IR) light source illuminates the finger.
  • Hemoglobin in the blood absorbs near-infrared light,
allowing the detection of finger vein positions.
  • The internal finger vein pattern is analyzed by
distinguishing areas that absorb light (darker regions)
from areas where light passes through (brighter regions).

Finger vein Pattern Image Generation

  • Specialized sensors capture and convert finger vein patterns
into images.
  • The captured images are transformed into unique biometric
data and securely stored in an encrypted format.

Data Comparison and Authentication

  • During authentication, the newly captured finger
vein pattern is compared against the pre-registered
pattern data to determine a match.

Features of Technology

Discover the key advantages of
finger vein authentication — safer than fingerprints and more accurate than facial recognition.

Uniqueness

Finger vein patterns are unique to each 
individual, even among identical twins. This
ensures a high level of security.

Fast Authentication Speed

The authentication process is completed 
within one second, enabling real-time
authentication.

Anti-Spoofing Protection

Finger vein patterns are based on subcutaneous blood vessel structures, making
them difficult to replicate or forge externally.
This results in lower susceptibility to spoofing
compared to fingerprint or facial recognition.

Biological Response Verification

The system verifies whether blood is actively
flowing (detecting blood circulation) to prevent authentication attempts using artificial models or deceased individuals.

Resistance to External Environmental Factors

Since veins are located beneath the skin, they 
are minimally affected by external environmental conditions such as humidity, temperature, and dust, as well as surface conditions of the hand, including cuts, sweat, or oil.

High Durability of Authentication Area

Since veins are not affected by external damage (e.g., fingerprint wear or facial wrinkles), long-term authentication accuracy is maintained. The system is also resistant to issues caused by sweat or oil.

High Accuracy

The authentication process is fast, with low false rejection rates (FRR) and false acceptance rates (FAR), ensuring high reliability.

Multi-Factor Authentication (MFA)

Finger vein authentication can be integrated with other security measures such as passwords and RFID to enhance overall security levels.
