Abstract

A social networking site host includes, in a user'"'"'s profile, information that has been attested to and verified by both the user and an independent verifier. The independent verifier is an accepted authority with direct knowledge of the information. Both the user and verifier attest to the information by digitally signing the information and including the digital signature with the information. The host or visitors to the social networking site can authenticate the information by using both digital signatures. By authenticating the information, visitors and users viewing information on the social networking site can assume that the information is trusted and accurate.
