In the field of security technologies, from secure access to electronic devices and bank accounts to personnel time attendance systems and access control to restricted areas, one of the fundamental challenges is the need to securely authenticate the identity of individuals. Currently, systems based on measuring biological characteristics, intrinsic to the person themselves and therefore difficult to transfer or steal, are becoming popular. For example, facial features, fingerprints, iris patterns, retinal scans, earlobe geometry, gait analysis, among many others. These techniques are known as biometrics and they provide credentials that do not depend on the end user to maintain their security.
