The New York Times reports on the increasing use of facial-recognition technology on the general public, such as in a bar. As identification technology becomes cheaper and more prevalent, it could easily unmask people and track their movements. Those who were previously part of the unnamed crowd could be singled out for identification. See this previous post for a discussion about the First Amendment right to free speech and how widespread identification technologies can affect that. More of my thoughts on facial recognition in this older GCN interview.
The Times reports:
SceneTap, a new app for smart phones, uses cameras with facial detection software to scout bar scenes. Without identifying specific bar patrons, it posts information like the average age of a crowd and the ratio of men to women, helping bar-hoppers decide where to go. More than 50 bars in Chicago participate.
As SceneTap suggests, techniques like facial detection, which perceives human faces but does not identify specific individuals, and facial recognition, which does identify individuals, are poised to become the next big thing for personalized marketing and smart phones. That is great news for companies that want to tailor services to customers, and not so great news for people who cherish their privacy. The spread of such technology â€” essentially, the democratization of surveillance â€” may herald the end of anonymity.
And this technology is spreading. Immersive Labs, a company in Manhattan, has developed software for digital billboards using cameras to gauge the age range, sex and attention level of a passer-by. The smart signs, scheduled to roll out this month in Los Angeles, San Francisco and New York, deliver ads based on consumersâ€™ demographics. […]
But facial recognition is proliferating so quickly that some regulators in the United States and Europe are playing catch-up. On the one hand, they say, the technology has great business potential. On the other, because facial recognition works by analyzing and storing peopleâ€™s unique facial measurements, it also entails serious privacy risks.
Using off-the-shelf facial recognition software, researchers at Carnegie Mellon University were recently able to identify about a third of college students who had volunteered to be photographed for a study â€” just by comparing photos of those anonymous students to images publicly available on Facebook. By using other public information, the researchers also identified the interests and predicted partial Social Security numbers of some students.
