A biometric system is a recognition system, which makes a personal identification by determining the authenticity of a specific physiological or behavioral characteristic possessed by the user. This method of identification is preferred over traditional methods involving passwords and PIN numbers for various reasons:
· The person to be identified is required to be physically present at the point of identification.
· Identification based on biometric techniques eliminates the need to remember a password or carry an identity.
But it has its own disadvantages; Behavioral traits such as voice and signature are vulnerable to spoof attacks.
The prominence and acceptance of biometric technologies such as fingerprinting, facial recognition, hand geometry, and iris recognition may leave little demand for other modalities. However, the emerging vein-pattern recognition technology, with its own unique features and advantages, has maintained its position against the others.
The up-and-coming biometric technologies include vein, DNA, ear, and body odor recognition. Of these, vein pattern recognition is gaining momentum as one of the fastest-growing technologies. It is on course to become the newest entrant to mainstream biometric technologies, moving from the research labs to commercial deployment.
Fujitsu has developed a contactless palm vein pattern authentication technology that uses vascular patterns as personal identification data. Vein recognition technology is secure because the authentication data exists inside the body and is therefore very difficult to forge. It is also highly accurate — in testing using 140,000 palm profiles of 70,000 individuals, it had a false acceptance rate of less than 0.00008% and a false rejection rate of 0.01%*.
Palm vein authentication technology:
Palm vein authentication works by comparing the pattern of veins in the palm of a person being authenticated with a pattern stored in a database. Vascular patterns are unique to each individual, according to Fujitsu research — even “identical twins have different vein patterns”. And since the vascular patterns exist inside the body, they cannot be stolen by means of photography, voice recording or fingerprints, thereby making this method of biometric authentication more secure than others.
