An upcoming app for Android, iOS, and Google Glass called NameTag will allow you to photograph strangers and find out who they are – complete with social networking and online dating profiles.
Spot someone out and about that you want to identify, and you can capture their face using your device’s camera. The app will send the photo wirelessly to NameTag’s server, where it will compare the photo to millions of online records and return with a name, more photos, and social-media profiles, such as Facebook, Twitter, and Instagram, where the person (or their friends) might have publicly posted photos of themselves.
In the United States, it will match the photo against the National Sex Offender Registry and various other criminal databases.
The battle between privacy and accountability seems to be stepping up. It will be interesting to see what questions and debates come out of all this.
