Imagine walking down a street and having a total stranger being able to instantly pull up your name, date of birth, Social Security number, your last blog item and other data on their smart phone.

In a presentation at the Black Hat conference here this week, Acquisti demonstrated how it's becoming easier for strangers to identify people and infer detailed information about them from their publicly available images on sites such as Facebook and LinkedIn.
