What is biometrics?

From biometrics in correlation to the personal identification one can understand individual recognition by means of unique and inexchangable biometrical characteristics. These characteristics are instantaneously associated with the individual's body and do not have to first be sorted. The biometrical process includes association with physiological characteristics that conclude personal identification. This process includes the following:

Fingerprint recognition: A biometrical process functioning through optical, capacitive, thermal or direct optical sensors. This leads to a form of technology with high quality recognition capabilities.
Face recognition: At time of recognition exposures of the face are taken and detailed traits of the individual's face are saved as templates. These templates will furthermore be compared with the original exposure of the individual's face.
Iris recognition: A unique identification feature, similar to a fingerprint, is the structure of the connecting tissue between the cornea and iris which can be detected with a camera.
Venous recognition: A person's vascular structure is identified by taking an infrared exposure of the hand.
Hand Geometry: A priceworthy process, but therefore leading to more weaknesses in detection.

Why Biometrics?

Biometrical recognition focuses solely on the user. It is advantageous in that the user is never required to have a form of personal identification on hand or to remember a password.

Biometrics detects and saves specific physical attributes of the user, which are also not able to be exchanged or misused as with passwords or Ids.

Biometrics can therefore be used as an alternative to or in addition to other identification methods, such as passwords in time management or access control systems, because the user's physical attributes that are retained are not interchangeable.
