Facial recognition technology is in use throughout the world -- and ready to change the planet, NBC News reported.
The most recent sign of the revolution came with statement fresh iPhones are employing the technologies.
However, NBC News reported in China, the technology is currently in office buildings and at ATM machines, even while high-end European resorts and retailers use it identify star customers -- and Australian airports are installing a system to allow passengers get through security without passports.
"Everyone's face is slightly different, so it's almost like a 3D fingerprint," Lyndon Smith, professor of computer simulation and machine vision in the University of the West of England, told NBC News. "Even identical twins, you can differentiate between them if you're applying this type of technique."
"Wherever you go in the world ... you could, rather than carrying a card around with a PIN and all this sophistication, just simply use your own face," he added.
According to NBC News, researchers in the U.K. and India have developed a system which can even see through disguises. Its goal, says researcher Amarjot Singh, a graduate student in engineering at the University of Cambridge, is to "take a lot of criminals off of the streets."
"Essentially you've developed an X-ray to look into people's individuality, and that I think is very exciting," he told NBC News.
The revolution has sparked some anxiety.
Last week, Stanford University researchers triggered a controversy when they released study indicating facial recognition can predict sexual orientation, NBC News reported.
"Our intention is certainly to not have some type of Big Brother thing going on; we would not want this system to be employed by anybody who didn't want to use it," Smith told NBC News. "We are not trying to monitor people -- we're trying to help people in their daily lives."
