What is biometrics?

State-of-the-art security

The use of modern electronic equipment, i.e. ATMs, mobile phones or PCs, is inconceivable without security systems.
Passwords and PINs are used to prevent fraudulent use.
The deluge of PIN numbers and passwords for credit cards, online banking and all forms of online services increases individual transaction costs and it becomes increasingly difficult to find your bearings in an increasingly connected world.

The introduction of the Internet, e-commerce, m-commerce has put an end to an exclusive control for physical identity documents, namely passports, identity cards and driving licenses.
As far as new media are concerned, biometric identification procedures are predestined to become the standard in authentication and identity assessment. Alternatives have become indispensable to cope with the increasing complexity and individual overload by memory processes.

One promising approach is the use of biometric identification procedures that rely on identification or verification by personal or bodily characteristics. Biometric identification procedures are user-friendly and more convenient than having to memorize passwords or carry key cards or transponders. Biometric systems provide low-cost, fast identification for a wide variety of applications.

Biometric procedures use the capabilities of computers in conjunction with sensors or other recording devices to measure and evaluate human body or behavioral characteristics.
The purpose of biometric recognition is to extract relevant information about body and behavioral characteristics in order to determine a person's identity (identification), or to confirm or reject their presumed identity (verification). Authorized persons are thus distinguished from unauthorized persons. A biometric system is essentially based on pattern recognition.

The term "biometrics" is composed of "biology" and "metrics". Biology is the science of living things and the regularities and characteristics of living things.
Biometric methods include a variety of procedures: fingerprinting, finger geometry, face, hand geometry, iris, retina, speech recognition, signature detection and vein recognition. All these elements are subject to very different technical characteristics and success statistics.

The correct combination of procedures ensures both safety and convenience.
We mainly use fingerprint terminals for access control and time registration.
