How do you enter your email? And on your social networks? The answer is obvious: via a password. Smartphones are also used on smartphones (called a PIN, this combination of four or six numbers that only you know), although many prefer that the terminal itself reads the fingertips, or else recognizes the face or retina. Biometrics
This is called biometric identification and this practice is the future of personal identification in place of passwords.
Biometrics consists of identifying the unique characteristics of each person to prove their identity in a computer system .
Are they really unique? Are there not two people with the same fingerprints or whose iris reading can give us the same results? While technology has its limitations, the answer to the first question is yes, and the second is no.
Both fingerprints and the iris of our eyes have characteristics that make it practically impossible to repeat the same pattern and historical moment. Let’s imagine that a 6th century Japanese countryman d. C had the same iris than mine and passed through the biometric recognition system, this would represent a risk to security . Biometrics
Biometric recognition systems have become popular on mobile devices thanks to improved reading systems, their miniaturization, and the cheapness of their manufacture and inclusion in an electronic device.
So, for example, any latest generation smartphone now has a fingerprint reader as a software that allows you to read and interpret faces, irises and retinas. The latter is possible thanks to the front camera, which has been used for some time, in addition to an infrared LED light that serves to illuminate the biometric element to be read.
However, before smartphones, some portable computers already had a fingerprint reader to facilitate their unlocking. But why specifically laptops? Because they are the most susceptible to being lost or misplaced.
Currently, these biometric systems are combined with traditional identification systems through passwords or pins. Biometrics
While it is easy to intercept or decode a password, it is not trivial to circumvent the security of a biometric system.
For this, there are few options to present to the reader, that is, the original element to be read. Afraid that a finger will be cut off or an eye taken out to access important data ? Don’t worry: to make a correct reading, blood must flow through the finger and the eye, what is required of these elements is that they remain “placed” in the body.
With this, companies that manufacture and implement these systems seek to avoid possible extreme violence to force access to the devices. Biometrics
Other biometric control measures include reading the shape of the palm of the hand and the veins in the fingers (or, eventually, the hand or other parts of the body).
The future of biometrics is to replace current passwords so that we don’t have to remember any combination of letters and numbers, but we still need to live with passwords and pins for a long time.
