1.   Facial recognition technology is coming of age. The new iPhone can be unlocked simply by looking at it, and accessing your smartphone is just one of many ways that facial recognition will change our daily lives. Soon we'll be using our faces to pay for groceries, catch trains, pass through airport security, and more.
  In China, you can already use your face to gain access to office buildings and authorize ATM withdrawals. In Europe, high-end hotels and retailers use it to identify celebrity customers to make sure they get special treatment. Australian airports are installing a system that lets airline passengers glide through security without passports--and facial recognition systems are beginning to appear in U.S. airport too.
  "Everybody's face is slightly different, so it's almost like a 3D fingerprint," says Lyndon Smith, professor of computer simulation and machine vision at the University of the West of England. According to him, we can even differentiate between identical twins when we're applying this kind of technique. Smith is developing a system that he believes could replace train tickets. Like the new iPhone, it uses infrared scanning to recognize patterns in facial features and then compares them against a database of known facial patterns. He claims the system would work well in stores and banks as well as train stations, so wherever we go in the world, we could, rather than carrying a card around with a PIN and all the complexity, just simply use our faces.
  Experts say facial recognition systems can be extremely reliable. Apple claims its new iPhone has no trouble telling a real face from a photo--and can even recognize individuals if they grow a beard or wear eyeglasses. And researchers in the U.K. and India have developed a system that they say can peer through disguises--including fake beards and scarves that obscure part of the face. It uses 14 key landmarks around the eyes, nose, and lips. That is, if some factures are hidden, it uses others to make the identification.
  The system is intended to "take a lot of criminals off of the streets," says Amarjot Singh, a graduate student and one of the researchers in engineering the University of Cambridge. He is excited that the system can function well as an X-ray to look into people's identity. Excitement aside, Singh is among those who worry that the rise of facial recognition technology raises privacy concerns. Some worry governments could abuse the systems to assert inappropriate control over their citizens and stifle protests. Others worry that facial recognition systems will reveal information that individuals might wish to keep private. Last year, Stanford University researchers sparked a controversy when they published research suggesting that facial recognition can predict an individual's sexual orientation.
  The bottom line? Facial recognition technology is already out there, although how to use it without putting people at risk invading their privacy remains a hot debate topic. Smith insists that their intention is certainly not to have some kind of Big Brother thing going on; they wouldn't want this system to be used by anybody who didn't want to use it. He reassures the public that they're not trying to monitor people--they're trying to help people in their everyday lives.
