Facial Recognition a breakthrough for Access and Security

Facial recognition technology should not be perceived as intrusive or disproportionate. There are many functionalities in terms of security, such as its use to unlock a mobile phone as access control in high-security places, which do not generate any type of ethical debate.

The facial recognition market is a global trend with a movement of US $ 9,000 million in four years, representing an average growth of 16% per year in the world.

In Europe and America it is increasingly common to find this solution guided mainly to experiences other than transactions such as access controls or airports and now in Colombia, one of the Latin American countries that implements this mode of payment in facial processing.

As for the private sector, some large corporations such as Google, Facebook, Apple, Amazon, among many others, also use this technology for purposes ranging from security to improving the user experience of a service in its different variants, allowing As an example, making payments through a smartphone using such technology, automatic tagging of photos on a social network, improving the agility of some procedures, etc.

Facial recognition is a technique that enables the extraction of biometric data that allows individuals to be uniquely identified, they respond to physical or mental behavior of the person.

There are different biometric data in our bodies such as fingerprint, iris, voice, hand geometry, or even the way of walking or typing, among others. These data can be obtained through the use of a technology called “biometric technology” or “biometry”, which by means of sensors is capable of extracting and analyzing parameters.

Biometric technology is ultimately a method that enables the recognition of people through their physical, physiological or behavioral characteristics from the extraction and analysis of the resulting biometric data, which allows identifying or confirming the unique identity of a person. With this, insofar as the result of the data obtained by means of biometric technology allows the unambiguous identification of a subject, it is possible to confirm that a treatment of personal data is carried out.

Artificial Intelligence has already become a very important geostrategic element, hence the pressing need for the EU to have an autonomous and strong position in this field. Another thing will be to fall into a future “remote controlled” by foreign powers, whose interests often do not coincide with ours.

How does facial recognition work?

Face recognition is used in the aforementioned dynamic social media filters. But one of the uses with the greatest potential for this technology is related to security.

Where a face is seen, the machine sees numbers that indicate colors and shapes, the algorithm simplifies those numbers and allows the device to identify the light and shadow areas of a human nose. The bridge is lighter, the sides darker. Or to identify the eyes, or the subtle differences in shadows and highlights of lips or cheekbones. Of course, this implies that the image is divided into thousands of areas, which requires good image quality.

Enabling an artificial intelligence tool requires a fundamental component: digital data, which is the fuel that powers and makes any Machine Learning or Deep Learning tool more powerful.

Capture: In a first stage the image is captured. A standard photo, come on. For example, a photo with good lighting.

Extraction: What happens next takes milliseconds. In that time, the smartphone’s processor transforms that photo into information that can be analyzed by the algorithm and establishes whether what is in front of it is a face or a different object.

Comparison: Immediately, the speed given by the smartphone processor compares that face with its database and immediately estimates whether it is a person or a third party

Match: If the processor recognizes the face, it is that of someone authorized, it proceeds to unlock the smartphone.

There is no doubt about the unstoppable nature of this technology and the wide range of uses it provides. In fact, technological advances are good and positive in a society and, as a general rule, it is not appropriate to think that there are limits to technology.
