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.
Process for extracting vascular pattern information

Back-of-hand Raw image Enhanced vascular pattern Feature Points
Vascular Pattern Encryption and Storing
VP-II encrypt the features by AES algorithm and store with ISO 19794-9 CBEFF international standards.
