NEW YORK: Google has developed a new service called Latitude that will mean mobile phone users will be able to track the movements of their friends and family. Those using the Latitude tool will be able to see exactly where their contacts are on a detailed map, using their own phone or computer, and then watch as they move along streets.However, the launch has raised concerns about security. It is expected that the feature, called Latitude, will prove popular with parents who want to keep tabs on the whereabouts of their children without having to call them, and with groups of friends trying to meet in busy city centers or at musical festivals. Latitude plots the position of mobile users by finding out which phone masts or wireless Internet hotspots they are close to. This technique, known as triangulation, has long been possible and is used in court cases to place a defendant at the scene of a crime. The service can even provide directions to help mobile users navigate their way through the streets to meet their friends.
