Risks and benefits of biometric security systems


A week ago we brought you a series of tips to create a good password . But the password is not the only way to protect our devices, files or accounts. For the films, we know that the best authentication systems are those based on biometric systems such as fingerprint reader or iris. But are they really safe? Can we trust them?

What is biometrics?

Let's start at the beginning. What is this about biometrics?
Biometrics is the study that allows us to unequivocally identify a person through their traits. In other words, it allows us to verify the identity of a person, or what is the same, to authenticate it, through their physical characteristics or biometric features .
And what physical characteristics can serve us? The most popular way are fingerprints , in fact, many already have fingerprint sensors on their mobiles to unlock it. But it is not the only physical feature employed, it also highlights the use of iris scanner or vascular recognition .
And on what traits can a biometric system be built? Despite not being the only identification mainly used voice . Also, in this category we could also include features of the sharing , which is where authentication methods such as signature or keys, which would come to be "traditional systems" are included.
The voice is also considered a biometric security system, despite not being a physical characteristic (which is what is popularly understood by biometric system).

The Advantages of Biometric Authentication Methods

Biometric authentication systems are increasingly present . Without going further it seems that it was yesterday when Apple via the Touch ID on the iPhone 5S caused the "fashion" of incorporating fingerprint readers on their devices. But now it is not just something that stays on the phones or tablets , but now it is also something that has come to the computers  (even before Apple with the MacBook Pro and Microsoft with the new Surface decided to do so).
And obviously we can not stay there, and is that many devices also include face recognition . Even some brands are also beginning to perfect the iris recognition systems, to be able to incorporate it into their future devices. Why so much interest? Obviously this has to bring some advantage , but all these companies would not "wasting" precious time ...
The main advantage is increased security . And is that as a general rule, a fingerprint protection, iris scanner or any other system we have seen, will always be more secure than a password, however secure it may be. Basically because the probability of discovering how your footprint is or your iris is much lower than that of discovering your password.
A biometric security system increases your security, as it should generally be more difficult to penetrate.

Their disadvantages and risks

Despite being very sure, they have their weaknesses . But improving your security is possible, and it is the task of both manufacturers / developers and users.
As far as the users only have a mission, and is not to rely on excess in the biometric security systems. Why? For two reasons. The first is that not all biometric security systems are the same, and not all are equally secure . In this way, it is possible for some fingerprint sensors to authorize a person who only has a photocopy of your finger, for example. In addition, it is also important to have a plan  B , and is that if you trust your security exclusively in a fingerprint, what happens if you unfortunately lose your hands? Exactly, you would be left without your data, although hopefully it will not happen ...
What about manufacturers and developers ? It is up to you to keep your biometric data safe (and I will try to explain as simple as possible, because it is very important). Although if someone steals your password you can change it at any time by another, this is not possible with your biometric data . That is, if someone gets the complete data of your fingerprint, you can never change it. And this is the biggest risk of using biometrics so broadly and carelessly.
The strength of biometric systems is security, but theft is their greatest weakness.
Your strong point is security, but theft is your greatest weakness.

Conclusion

I think the most important thing in this article is the last paragraph that I have just written, and for that I will not say anything else, so that you may remain as a reflection .
Do you think it is safe to entrust our biometric data, that is, our identity, to our devices? Will there be any way to be sure that these will not be used maliciously? The truth is that it is something that I have no answer ...
