If we go back to the etymological sense of the word we can find the union of the greek´s ancient terms: “life” and “measure”, so it would be easy to define biometrics as the simple study or measurement of biological processes or phenomena. But what does this mean?

It means that we are in front of the science that is dedicated to measure and analyze the biological data, or characteristics of the alive organisims´ body, as well as its behavior.

Today we talk about biometrics when we are actually refering ourselves to biometric technology, also associated with the concept of security, personal and unambiguous users´ identification.

The current biometric science uses physical characteristics of each person such as:  fingerprint, facial recognition, iris, voice, geometric measurement of the body or hands, ears, structure of the veins, the pulsations´rhythm when writing on a keyboard, a dynamic signature (where the pressure and speed exerted by each individual is interpreted) or the DNA structure itself, among others.

These characteristics are also non-transferable and unique, which makes them fully suitable for the irrefutable recognition of any individual. That is why biometric technology or biometrics is spreading rapidly in processes that need reliable and solid authentication of the person who is performing them, such as: security systems, control of physical access (offices, or your own home) or control of secure access to computers, files, bank cards, e-commerce platforms, or cloud storage, etc.

This technique is advancing the processes of authentication and recognition where it is necessary to make sure that a person is who says it is, identifying itself in a safe, comfortable and fast way without using other systems that can be stolen, duplicated or shared as passwords, keys, or code systems.
