Abstract

Embodiments of a location sharing network manager process are described. The process is executed on a server computer coupled to a plurality of mobile communication devices over a wireless network. Each mobile device is a location-aware mobile communication device. The process determines the geographic location of a mobile communication device operated by a user within an area, displays a map representation of the area around the mobile communication device on a graphical user interface of the mobile communication device, and superimposes on the map the respective locations of one or more other trusted users of mobile communication devices coupled to the mobile communication device over the network. A security component allows users to establish trusted relationships by requiring mutual consent and disclosure of identifier and phone number information for each trusted user. Location information can be blocked among trusted users or obfuscated on the display of the mobile devices of the other users.
