Trends in security systems indicate that biometric identification devices are gradually imposing themselves against other authentication methods, such as the use of personal codes or physical devices, such as magnetic cards or bracelets. The biometric access control system comes up with the best choices now.

The recognition of a user through a physical quality is a huge advance in the field of computer security. The main characteristic is the impossibility of falsifying the identification, since each individual is invariably different from any other and, therefore, supplanting him in order to access an authenticated service is practically impossible. In addition, it has the advantage of not having to remember different passwords or codes, since we always carry the “key” with us.

However, this procedure has some drawbacks, such as the need to physically have the user be able to verify or, at least, the use of a biometric reading device that allows such identification.

Elements involved in this type of procedure

There are three main elements involved in this type of procedure, on the one hand, artificial intelligence enables constant learning, so that recognition is increasingly effective. Another of the necessary technologies in the use of biometric recognition applications is that of the recognition of forms, with the calculation of thousands of variables, Together with these, cryptology allows the registration patterns to be properly encrypted, such as that of the ocular retina or that of a fingerprint, and storing them in a database.

As in our day to day we recognize our interlocutors, biometric devices mimic human behavior, but from the side of the machine, which will be the one that interprets the most remarkable features, tone of voice or physical characteristics.

The technology allows biometric recognition types to be virtually infinite. Thus, we can find pattern models: that register and interpret body movements, such as the way of typing, walking or gesturing. They can also be based on physical characteristics, such as the aforementioned fingerprint, the color and tone of the skin or the timbre of our voice or even our body odor.

The choice of the biometric recording device will depend on various characteristics since each of them has its advantages, but also a series of disadvantages that can interfere with the result of the registration. Thus, we can find that, in voice recognition, the user is cold, hoarse or in a noisy context, which makes a clear interpretation of the record impossible. In the case of fingerprints, which may be one of the most reliable methods, there may also be elements that interfere with recognition, such as dirt or skin wounds, momentary or permanent.

In this process, the accuracy index of these devices, both of the hardware used, which must have high capacity sensors, and the software implemented for the interpretation of the records must also be taken into account. Thus, this process will be conditioned by the rate of false rejection and false acceptance, which is nothing other than the percentage of errors that the system may commit, allowing illegitimate access or denying legitimate users.
