Third-party applications, he argued, can take that data outside of the friendly confines of a social networking site and combine it with data from other sources to piece together enough information to steal a person's identity.
When a business contact from the LinkedIn world wants to become your friend on Facebook, do you accept the invitation, giving them access to the photos on your Facebook profile from last summer's rowdy beach party?
And what about the person you don't really know who wants to be your friend because you have some friends in common? According to Hoffman, that new friend may just be mining your social circle for information. As networks grow and more friends of friends (and their friends) are accepted by users, it's unclear who can be trusted.

According to Acquisti, people are more likely to divulge key personal information -- their photo, birthday, hometown, address and phone number -- on social networking sites than they would on other web sites
In one study, Acquisti found that that people will divulge information when they see others doing so. That tendency, he believes, may explain why so many people are willing to dish out personal information on the networks.

"People are more willing to divulge information for social purposes, and the lead users are 18 to 25 years old," Bradlow notes. "The social norms around privacy aren't going to be what they were before."
The information provides opportunities not only for legitimate business purposes, but also for the nefarious aims of identity thieves and other predators, according to faculty at Wharton and elsewhere.
Users of social networking sites, she said, should "beware of the five Ps" - professors, prospective employers, parents, police and predators....
Cavoukian says 77 per cent of all employers check out prospective employees on Facebook before they make hiring decisions.
