you want any information about a stranger, try the new facial recognition app on your iPhone, which can provide you his or her details by just matching a photograph on Facebook. Users can take a picture of anyone and run it through the Facezam app which will show them their Facebook profile. Facezam scans billions of Facebook profile images a second, which it accesses through a database for developers, until it finds a match. It claims to be able to link most photos with a profile on the social network within 10 seconds.
