They will probably look like Robocop, the Brazilian cops, who in 2014 might use special sunglasses, able to scan 400 known criminals per second from up to 12 miles away (even though they are optimized for about 150 feet). These glasses are wirelessly connected to a huge computer database that can compare the scanned faces with those of 13,000 people in the db.
Moreover, this device has also a screen which allows the officer to get instructions about the behaviour he should have with found out criminals. Maybe this type of sunglasses are going to be used during the 2014 Football World Cup, that surely requires advanced and strong surveillance systems. Nevertheless, if implemented in policemen’s daily activities, it could help to prevent crimes and increase the arrest of already known criminals.
In few words, these sunglasses have nothing to do with the already on the market glasses with camera, as they are designed not only to record facial profiles, but also to identify suspected people. They scans 46,000 biometric points on a person’s face and compares it against a very big criminal database and when they find a supposedly bad guy, a red light pops up inside the glasses and alerts the officer on what to do.
Military Police officials from Sao Paulo and Rio de Janeiro, which will both host key games in the World Cup, have already been given demonstrations of device usage. “It’s something discreet because you do not question the person or ask for documents. The computer does it. To the naked eye two people may appear identical but with 46,000 points compared, the data will not be beaten,” said Leandro Pavani Agostini, Major of Sao Paulo’s Military Police. Moreover, “the device will be useful to police trying to monitor many different locations and events, ranging from airports and bus terminals to concerts and football matches”.
In short, these particular glasses are changing video surveillance in wide places and events, giving the police officers the opportunity to avoid a preliminary physical contact with the suspected.
