Reverse matching relationships in networks of existing identifiers

摘要

A mobile device, system, and method are directed towards managing social networking information by employing a reverse matching search to identify those members of the social network that may have another person's identifier in their contact lists. The person may initially visit the social network site and provide an identifier either automatically or through a directed action by the person. A reverse search may be performed on members' contact lists to determine which contact lists include the identifier. If a match is found in a member's contact list, selected information about that member may be provided to the person. The reverse matching search may also be performed at various subsequent times to provide members information about new members to the social network.
