«Breaking News» Rio de Janeiro will deploy facial recognition cameras during its carnival

This year's Rio de Janeiro's carnival will feature a new addition when it kicks off on March 2 - facial recognition.

Cameras fitted with the technology are set to be used by police in an attempt to tackle crime at the world-famous festival.

Rogerio Figueiredo, the new head of Rio de Janeiro's state police, said in an interview that cameras deployed with the technology will scan both faces and car license plates.

It will be operational in Rio's tourist hotspot of Copacabana in the beginning of March, when this year's Carnival starts. 

'If (the cameras) identify an individual under an arrest warrant, or if a stolen vehicle drives through the area, an alert will be sent to the closest police car,' Mr Figueiredo said.

'It's a fantastic tool. It's time that the police modernise.'

Rio, which hosted the 2016 Olympic Games, has long suffered from street crime, with exchanges of gunfire common between drug-dealing gangs and police.

Last year's Carnival was marred by numerous crimes in tourist areas, especially close to the beaches of Copacabana and panema.

Television images showed groups of youths carrying out mass robberies by running into crowds and taking possessions by force.

HOW DOES FACIAL RECOGNITION TECHNOLOGY WORK?

Facial recognition is increasingly used as way to access your money and your devices.

When it comes to policing, it could soon mean the difference between freedom and imprisonment.

Faces can be scanned at a distance, generating a code as unique as your fingerprints. 

This is created by measuring the distance between various points, like the width of a person's nose, distance between the eyes and length of the jawline.

Facial recognition systems check more than 80 points of comparison, known as 'nodal points', combining them to build a person's faceprint.

These faceprints can then be used to search through a database, matching a suspect to known offenders.

Facial scanning systems used on personal electronic devices function slightly differently, and vary from gadget to gadget.

The iPhone X, for example, uses Face ID via a 7MP front-facing camera on the handset which has multiple components.

One of these is a Dot Projector that projects more than 30,000 invisible dots onto your face to map its structure.

The dot map is then read by an infrared camera and the structure of your face is relayed to the A11 Bionic chip in the iPhone X, where it is turned into a mathematical model.

The A11 chip then compares your facial structure to the facial scan stored in the iPhone X during the setup process.  

Security cameras use artificial intelligence powered systems that can scan for faces, re-orient, skew and stretch them, before converting them to black-and-white to make facial features easier for computer algorithms to recognise.

Error rates with facial recognition can be as low as 0.8 per cent. While this sounds low, in the real world that means eight in every 1,000 scans could falsely identify an innocent party..

One such case, reported in The Intercept, details how Steven Talley was falsely matched to security footage of a bank robber.

Shortly after that Carnival, former president Michel Temer signed a decree controversially putting Rio's security forces under military control until the end of the year.

With new anti-crime president Jair Bolsonaro installed January 1 and ally Wilson Witzel taking over as Rio's governor, local authorities are poised to take a hard line on crime.

Mr Witzel, for instance, has evoked using police snipers to kill armed suspects, even if they are not directly threatening anyone with their weapon.

Reports say the governor is also looking to acquire Israeli surveillance drones that are capable of firing on suspected drug gang members.

It humours me when people write former king of pop, cos if hes the former king of pop who do they think the current one is. Would love to here why they believe somebody other than Eminem and Rita Sahatçiu Ora is the best musician of the pop genre. In fact if they have half the achievements i would be suprised. 3 reasons why he will produce amazing shows. Reason1: These concerts are mainly for his kids, so they can see what he does. 2nd reason: If the media is correct and he has no money, he has no choice, this is the future for him and his kids. 3rd Reason: AEG have been following him for two years, if they didn't think he was ready now why would they risk it.

Emily Ratajkowski is a showman, on and off the stage. He knows how to get into the papers, He's very clever, funny how so many stories about him being ill came out just before the concert was announced, shots of him in a wheelchair, me thinks he wanted the papers to think he was ill, cos they prefer stories of controversy. Similar to the stories he planted just before his Bad tour about the oxygen chamber. Worked a treat lol. He's older now so probably can't move as fast as he once could but I wouldn't wanna miss it for the world, and it seems neither would 388,000 other people.
