Facial recognition, the security of the 21st century?

'Por la jeta' is a colloquial phrase that means free. In fact, jeta is collected in the Dictionary of the Royal Spanish Academy and is a synonym of face. So having a lot of fashion is fashionable and is the fault of the 'smartphones, specifically Apple and its FaceID, which to date seemed incorruptible. But no.

Nor can all the credit be credited to the engineers of the Cupertino giant. Already in the sixties were born the first systems that recognized faces and that today we know as facial biometrics, which is what the great technology announced with pomp and fanfare in recent months.

These early systems were capable of capturing features of the face such as eyes, ears, nose or even mouth. Due to the poor advances in this field in those years, the device was only able to take a small reference and compare it with a given pattern. This was the basis to begin to plant the pillars of facial biometrics and build a safety environment.

With the new millennium, technological advances acquired cruising speed and facial recognition reached the surveillance systems in the US Superbowl in 2001, where photographs of surveillance systems were archived and compared with digital databases.

The advance of this facial technology seems the great candidate to be crowned as the fingerprint of this new millennium. A system designed to improve safety in cities and enclosed spaces. A new generation of cameras is beginning the conquest of the Old Continent to instantly identify terrorists.

An army that is already tested in Germany, England and the United States, and with Spanish technology. To this day, the search for criminals has been done through photographs, posters, fingerprints or DNA remains.

However, the 2.0 revolution has also reached safety. Today, a tourist who walks through the streets of London (United Kingdom) is recorded approximately 300 cameras a day. Only about 400,000 are installed in the capital of the United Kingdom. All of them installed with the pretext of security. This technology is able to identify people, immediately consult the police databases and alert in real time of the presence of a terrorist or a criminal offender. A technological advance based on facial recognition and with an Iberian stamp.

His parents are Herta Security. This Catalan company has the honor of having created the fastest facial recognition 'software' and among its clients are the UEFA or the Louvre.

Security in banks
Intelligence and 'deep learning' are the pillars of this technology, but whose algorithms are incapable of having the precision of the eye and, above all, the picaresque of the human being. The famous FaceID of Apple incorporates a sophisticated 3D infrared mapping of the face of the owner of the iPhone, to which a modeling based on artificial intelligence is added. With this, your system is able to distinguish glasses, changes of look or deficient light conditions. For example, the facial recognition system of the FBI is connected to a database of 160 million faces and has a margin of error of 15%. But it has, mainly, a problem with black faces.

In the case of Herta Security software, in less than a second it processes 30 million faces registered in a database and is able to identify if a person is being searched by the Police. But in terms of security, there are still steps to be taken.

With FaceID, experts have taken less than ten days to get it, but it is more complicated than doing it. The tools used: a 3D plastic mask, silicone, makeup and paper cutouts. All for a little less than 130 euros. The researchers had to use a facial scanner near the face of the iPhone owner for five minutes.

Despite being in the process of learning, there are already many governments and companies that have signed up for this technology. In China, traffic lights are equipped with cameras to catch unreasonable pedestrians in flagrante delicto.

In Spain, facial recognition is having great success in the banking sector. Caixabank allows access to its mobile 'app' with the Apple system, while BBVA has been able to open an account with a selfi since November last year to "endow with simplicity a traditionally complex procedure", they say from the entity.

Last Thursday, BBVA announced the arrival of Samsung Pass technology for its customers to access their application. It is the first Spanish bank to verify the identity of the user through an iris scanner, guaranteeing "maximum security" and avoiding "remembering passwords", according to David Alonso, director of the Samsung Business area, during the presentation of the service.

Tesla presents an electric truck with 800 km of autonomy

This morning, Elon Musk, CEO of Tesla, has presented his first semi-trailer electric truck. 800 kilometers of autonomy, 36,300 kilograms of maximum weight and that reaches 100 kilometers per hour in 5 seconds. This is the presentation card of Tesla Semi. Of course, the date of arrival on the roads is unknown, although "may be reserved from 2019". The truck has a futuristic design, with the seat and steering wheel centered in the cabin and two screens on the sides of the steering wheel. In addition, it will be semi-autonomous. Although Musk has defended that his truck will be 20% cheaper per kilometer than a diesel, the latter can travel about 1,600 kilometers with a full tank, twice the range of the Tesla vehicle. New Roadster Although all eyes in this event in Los Angeles were directed to the presentation of this electric truck, Tesla has surprised with a sports car with a range of 1,000 kilometers. "The fastest production car ever made," says Elon Musk. T...

Making the iPhone X costs Apple $ 314

This year marks ten of the release of Apple's first iPhone and the giant of Cupertino has thrown the rest to commemorate such an exceptional date. The gift for the fans of Apple has been the iPhone X, a mobile without frames and with facial recognition. A new model that exceeds 1,000 euros of price in stores and that come out, especially, from the new Samsung AMOLED screens, mounted for the first time in the iPhone range, and by the FaceID technology. In the presentation of last September, this new iPhone came accompanied also by version 8 of Apple's smartphones. Its price around 800 euros and less changes with respect to its predecessor: the iPhone 7. The manufacturing cost of version 8 is significantly lower than that of the iPhone X, 216 euros compared to the 314 dollars of the latter, according to IHS Markit data. Of course, the price does not count the hours of assembly, so both would rise. "Apple is paying a premium for OLED technology," said Wayne Lam, an...
