Cell phones that can identify you by how you walk. Fingerprint scanners that work from 25 feet away. Radars that pick up your heartbeat from behind concrete walls. Algorithms that can tell identical twins apart. Eyebrows and earlobes that give you away. A new generation of technologies is emerging that can identify you by your physiology. And unlike the old crop of biometric systems, you don\u2019t need to be right up close to the scanner in order to be identified. If they work as advertised, they may be able to identify you without you ever knowing you\u2019ve been spotted.<\/p>\n\n\n\n
Biometrics had a boom after 9\/11. Gobs of government money poured into face and iris recognition systems; the Pentagon alone spent nearly $3 billion in five years<\/a>, and the Defense Department was only one of many federal agencies funneling cash in the technologies. Civil libertarians feared the worst as face-spotters were turned on crowds of citizens<\/a> in the hopes of catching a single crook.<\/p>\n\n\n\n But while the technologies proved helpful in verifying identities at entry points<\/a> from Iraq to international airports, the hype \u2014 or panic \u2014 surrounding biometrics never quite panned out. Even after all that investment, scanners still aren\u2019t particularly good at finding a particular face in the crowd, for example; variable lighting conditions and angles (not to mention hats) continue to confound the systems.<\/p>\n\n\n\n Eventually, the biometrics market \u2014 and the government enthusiasm for it \u2014 cooled off. The technological development has not. Corporate and academic labs are continuing to find new ways to ID people with more accuracy, and from further away. Here are 11 projects.<\/p>\n\n\n\n The Iris<\/strong><\/p>\n\n\n\n Imagine a scanner than can look deep inside your eye \u2014 from 10 feet away. Actually, you don\u2019t have to think that hard. The technology is already here. Scanners have been developed that can focus in and scan irises from a distance of 10 feet, such the IOM PassPort<\/a>, developed by government contractor SRI International. The company promises the machine can scan irises at a rate of 30 people per minute \u2014 like in high-traffic areas such as airports and train stations. SRI also claims it can see through contact lenses and glasses.<\/p>\n\n\n\n But the longer-range scanners could also see other uses, aside from airports. U.S. troops field existing, short-range and handheld iris scanners<\/a> to build databases of Afghan eyes as part of a plan to use biometric data to tell civilians apart from insurgents. The Department of Homeland Security has tested iris scanners<\/a> at a Border Patrol station along the Texas-Mexico border. The FBI has been working on an iris database for federal prisoners<\/a>, and Google uses them at company data centers<\/a>. But these systems can be fussy, and require that the targets don\u2019t move too much.<\/p>\n\n\n\n There might be another way. The Pentagon\u2019s scientists at Darpa have funded a research project at Southern Methodist University to develop cameras that can automatically\u00a0zoom-in and scan irises<\/a>, kinda like what happened to\u00a0Tom Cruise in\u00a0<\/a>Minority Report<\/a>\u00a0\u2014\u00a0<\/em>and without being blocked by pesky obstructions like eyelashes and glare from light.\u00a0But another problem is that iris scanners are not the most secure means of identifying people. In July 2012, a group of researchers from the U.S. and Spain discovered a way to\u00a0spoof the scanners<\/a>\u00a0by duplicating iris images stored in databases and creating synthetic copies. That means someone could\u00a0conceivably\u00a0steal your eyes, in a way.<\/p>\n\n\n\n Long-Range Fingerprint Scanners<\/strong><\/p>\n\n\n\n Most fingerprint scanners today require physical contact, but constantly being soaked with finger-oil and dirt can also muck-up the machines. For that reason, among others, one developer is working on a scanner that may one day read your fingerprints at a distance of 20 feet.<\/p>\n\n\n\n But first, scanners with a 20-foot distance haven\u2019t hit the market quite yet. One machine called the AIRprint, made by Alabama firm Advanced Optical Systems, has a range of nine feet, and uses two 1.3 megapixel cameras<\/a> that receives light in different wavelengths: one horizontally polarized, and the other vertically polarized. To sort out the different wavelengths, a device beams light at your fingerprints, which bounce back into the lenses, which then combines the separate wavelengths into a clear picture. A spin-off company called IDair also has a commercial scanner that reaches up to six feet and is marketed toward \u201csecurity personnel<\/a>.\u201d IDair\u2019s 20-foot-range machine is currently in development, and is described as functioning similar to satellite imagery<\/a>.<\/p>\n\n\n\n The military is reportedly an interested customer.\u00a0The\u00a0MIT Technology Review<\/em>\u00a0surmised<\/a>\u00a0that Marines may use them for scanning fingerprints from inside the relative safety of an armored vehicle or behind a blast wall. It beats exposing yourself to the possibility of a\u00a0suicide bomb attack<\/a>. For the civilian market, that seems better than pressing your fingertips against a greasy scanner, if you\u2019re comfortable with the idea of having your prints scanned from far away.<\/p>\n\n\n\n Sweat<\/strong><\/p>\n\n\n\n The Army wants to see some sweat. No, not workout sweat, but sweat that can betray hostile intentions. In 2010, the Army awarded a nearly $70,000 contract<\/a> to California security firm Irvine Sensors Corporation to develop software that can use sensors to recognize at \u201cabnormal perspiration and changes in body temperature<\/a>.\u201d The idea was to determine \u201charmful intent in such military applications as border patrol, stand-off interrogation, surveillance and commercial applications\u201d including surveillance at businesses and \u201cshopping areas.\u201d It\u2019s a bit out there, and still very much in the research stage, but makes a certain kind of sense. Elevated stress levels could give a suspect away when scanned by hyperspectral sensors that read changes in body temperature.<\/p>\n\n\n\n Though a reliable system will have to work in combination with other biometric signals: threatening body movements, facial expressions, iris scans \u2014 all of these will also have to be factored into determining whether someone is up to no good. The Army contract, dubbed Image Analysis for Personal Intent, also sought to develop sensors that read these signs from a distance of nearly 150 feet. Perhaps a bit optimistic. But in 2002, a group of scientists in Minnesota managed to determine if military recruits were engaging in deception by scanning for changes in temperature<\/a> around their eyes. So if you\u2019re at all freaked out about the idea of sweat-scanners, now might be time for a cold shower.<\/p>\n\n\n\n Analysis<\/strong><\/p>\n\n\n\n This article shares lots of new biometric technologies that are being introduced to the market that can identify a person in one way or another. For most of these, no contact is even required for them to get a read on you, with or without your consent. These machines can identify you by your ear, your odor, your heartbeat, your voice, your iris, your fingerprint, your walk, your face\/emotions, etc. There was one example where a machine can scan your fingerprint using light waves, so you don’t even have to touch your finger to anything to be identified. Another camera was able to zoom in on your iris and identify you individual coloring from 10 feet away, as long as you stay still. Another could scan your facial expressions to read your emotions. And another can use sensors to detect elevated stress levels to seek out hostile intentions before they escalate. All of these biometric technologies are being eyed by the military, but I think it might be interesting should they become commonplace in the day-to-day world. Imagine buying groceries and being able to purchase your apples by looking at a camera that identifies you and your checking account just by looking at your eye! Or confirming your identity when you’re at an ATM by holding up your hand to reveal your fingerprint before the ATM will let you work (no more PINs!). There are a lot of possibilities here. <\/p>\n\n\n\n Source<\/strong><\/p>\n\n\n\n Shachtman, N., & Beckhusen, R. (2013, January 25).\u00a011 body parts researchers will use to track you<\/em>.
