Hand Vascular Pattern Recognition

Biometrics The automated use of physiological or behavioral characteristics to determine or verify identity Physiological characteristics : Fingerprint, Face, Hand geometry, Iris, Hand vascular Behavioral characteristics : Voice, Signature, Keystroke, Walk

Biometrics

01

Hand vascular recognition

Technology to verify the identity individuals to analysis the information on the vascular

pattern dispersed

in the hypoderm of the back of the hand using the infrared optical system

General Factors Recognition accuracy Speed User perception Usability

Metrics FAR: False Acceptance Rate FRR: False Rejection Rate Usability: the percentage of unspecified adult population that is capable of using a system

VP-ll System

02

1. Best usability-VP-II technology provides ultimate system

Usability of 99.98%-Verification Speed: 0.4sec/person

2. Robustness to Forgery-Vascular pattern does not leave residual

pattern as it is the only feature which is located inside of human body.

3. Psychological acceptance-Out of a poll of more than a thousand users who have experienced multiple

biometric technologies, VP-II system has been chosen as psychologically the most

well accepted system.

4. Robustness to inferior environment -VP-II system demonstrates its great

tolerance in harsh environment, such as construction sites, army, factories, etc.

Algorithm

* ISO/IEC 19794-9 (Published in 2007) Information technology: Biometric data interchange formats – Part 9: Vascular image data

VP-II system obtains the vascular pattern image as the highest quality applying HVPE (Hand Vascular Pattern Emphasizing) algorithm for compensating the weak vascular vessel images and enhancing the pattern recognition

performance.

Vascular Pattern Encryption and Storing

VP-II encrypt the features by AES algorithm and store with ISO 19794-9 CBEFF international standards.
