A newly-published Apple patent application suggests the company is working on a location-based social networking service referred to as “iGroups.” The application describes a system through which multiple iPhone, iPad, or iPod touch users at an event, meeting, or other gathering could exchange information automatically by having their devices exchange encrypted, location-tagged “tokens,” which would then be sent to a trusted service—such as Apple’s MobileMe—and used to determine that all the users were at the same place or event. Once this has taken place, the users could then send location information and messages amongst the group as they move about and experience the event, potentially facilitating discussions on where to meet after the event is over, and also making it possible to precisely locate non-GPS devices by determining their proximity to a GPS-enabled device using a short-range communications protocol such as Bluetooth. As with all Apple patents, this filing does not necessarily represent any future product release from Apple, but offers evidence of the company’s research in this area. [via Patently Apple]
