The Mobile Weblog has this interesting post:
"One of the bigger stories over the weekend has been the resurgence of issue of companies using cellphones to track employees. With an increase in the number of devices that support GPS queries, or just the greater ability to triangulate a cellphone based on the current cells that handset is using, the number of firms that offer tracking services has grown dramatically.
According to a story from ZDNet, the sheer number of firms now offering this service is starting to raise privacy concerns.
Not everybody is happy about being monitored, however, and civil rights group Liberty says the growth of tracking raises data privacy concerns.
Kevin Brown, operations director of tracking firm Followus, said there was nothing covert about tracking, thanks to strict regulations.
"An employee has to consent to having their mobile tracked. A company can't request to track a phone without the user knowing," he said. "Under government rules we send random alerts to each phone we track, informing the user they are being monitored."
All that is needed to trace a mobile phone is a computer with an Internet connection. Once a phone is activated for tracking, it becomes a mobile electronic tag and its approximate position can be followed using the service provider's Web site."
