Biometrics is being used more and more in our everyday lives as it is a mechanism that adds greater security for private data management. Biometrics is the study of the physical and behavioral characteristics of living beings. This concept is used as a means of identifying an individual through their unique characteristics.

The main elements of a biometric system are capture, extraction and comparison. In the first element, there is the possibility of acquiring a biometric sample in order to identify an individual. In extraction, a sample of unique biological information is selected so that the identification can be made. The result of this selection is called a biometric signature, which is nothing more than a set of data to be used in future comparisons.
