Biometric security Is it the end of passwords?


Biometric security has been used since the middle of the 20th century in different organizations such as method of protecting access to specific areas, record of compliance with schedules, among other operations that apply a certain restriction where the use of fingerprints, the retina, the iris, facial patterns, hand veins or the geometry of the palm of the hand, or the tone of voice made personal records has served as a way to ‘verify’ the identity of users.

So we could say that biometrics is about a biological (anatomical and physiological) and behavioral characteristic that can be used for automated recognition methods. This advanced technology is already used in a variety of actions that require identity verification of users, for example banking, access to homes or offices and lately for the locking and unlocking of smartphones.biometric security.,However, even though this method could be the most viable security technique in countless functions, there are still many concerns that arise for its use.

Advantages of biometric security

Like any other technology, biometrics has a number of advantages and disadvantages when applied. And it could be said that the main one is that it is more comfortable and safe than traditional systems like passwords, keys, or cards.

In the same way, we can take advantage of this high technology that you can not lose since the identification element is a part of ourselves and not an external device such as cards or keys, among others.

Among other advantages of this system is that no maintenance costSince there is no external identification device, it does not have to be renewed from time to time due to expiration, damage, theft or loss.

And if you are one of those people who has many accounts, but little memory, this would be your solution, since there is no password, cannot be forgotten.

In addition, the biometric security system it is complex to falsify and it can be combined with other current security systems.

And surely these advantages could be expanded to a lesser or greater extent depending on the biometric technique used.

And disadvantages …

Unfortunately, there are also several disadvantages within biometric security, since apart from exclude those who for one reason or another possess an anatomical impairment, too there are ways to cheat biometric systems little elaborate, derived from the fact that the features used are not secret.

For example, if we use the face of a person to access a 2D system, this could be to replicate it with the use of a photograph, not only would access be obtained, but even if such access is detected, it can hardly be replaced. If someone steals a biometric pattern, it remains stolen for life, since a face cannot be replaced.

It is also possible to use a silicone finger with the fingerprint of a person to access an enclosure protected by a fingerprint reader. Just as you can imitate the voice or the way of walking to fool different systems.

In the same way, it is true that these frauds can be remedied with the development of robust systems, with the application of measures that allow differentiating between photos and real faces using 3D modeling techniques, or verifying that the finger being analyzed is alive using the analysis of its blood vessels, as well as using various techniques to make access difficult due to the replication of any of them.

Benefits of using biometric security

We have already mentioned that this system has been used in many ways to verify the identity of people without the need to use any card or other portable system other than part of their anatomy, particularly using the eyes, various dimensions of the hand, writing and signature, as well as voice and facial features, which, depending on the system used, could be more or less passable.
