Face recognition app matches live faces to Facebook profiles so you can choose who to chat up.
It is possible to identify strangers and gain their personal information using face recognition software and social media profiles, according to a new study by Carnegie Mellon University's Alessandro Acquisti.
When we share tagged photos of ourselves online, it becomes possible for others to link our face to our names in situations where we would normally expect anonymity.
Acquisti said his research team, which included CMU postdoctoral fellows Ralph Gross and Fred Stutzman, combined three technologies, an off-the-shelf face recognizer, cloud computing, and publicly available information from social network sites to identify individuals online and offline in the physical world.
The team developed a mobile phone app that identified students walking on campus based on their profile photos on Facebook.
Another application matched anonymous photos from a dating site with Facebook profiles.
