Finger vein readers

Vein readers identify the complex vein pattern below the skin, specific to individuals and unchanging throughout the lifetime.

Finger vein reader is a biometric device that comprises at least one optical imaging unit designed to capture finger vein patterns of an individual and a digital signal processer that digitizes the captures finger vein patterns to be utilized as biometric features.

Finger vein authentication, introduced by widely Japanese banks is claimed to be the fastest and most secured biometric method.

The finger vein reader is as small as most fingerprint scanners (39 x 34 x 15 mm) and the raw data are processed to yield a small template. Because the device is measuring the light absorption of hemoglobin, it will only work with a live finger or hand.

Finger vein advocates counter that the transillumination of the fingers redness its vein pattern features to be highly distinct band enables greater accuracy.

Nevertheless finger vein systems do have at least some specific, incontestable advantage over hand vein systems –numerical superiority. Fingers have a 5:1 numerical advantage and 10- fingers offer a variety of application options.

In terms of research, it is easier to build a bigger pattern database. This is a big advantage because the number of people using such system increases, so the testing database of samples must be much larger than in the past.

Biometric access systems

Biometrics is a general term used to describe a characteristics or a process. Biometric systems recognize a person based on physiological characteristics. Example of physiological characteristics, include fingerprints, hand, and facial features and iris patterns, or behavioral characteristics that are learned or acquired, such as how a person signs his name, types, or even walks.

Some systems today use keystroke dynamics to recognize an individual’s unique typing pattern to authenticate the user as he or she types in his or her username and password; other systems identify an individual via his or her voice, signature or gait.

The system matches the supplied biometric data with the biometric data that was stored in the database when individuals was enrolled in the systems and authenticates the individuals if the data matches.

To speed up the process, many biometric access systems require users to identify themselves first such as entering a username or swiping a smart card.

Biometrics offers a secure means of limiting access to sensitive facilities and computer and networking assets. Biometric access systems are used to control access to secure facilities such as corporate headquarters and prisons; to log users on the computers, networks and secure Web sites; to punch employees in and out work; and to confirm consumers’ identities at ATM machines and check-cashing services.

This biometric is preferred over traditional methods for primary two reasons:
*The person to be identified is required to be physically present at the point of identification.
*Identification based on biometric techniques obviates the need to remember a password or carry a token.
