JEFFERSON CITY, Mo. -- The Missouri Department of Transportation is negotiating with private contractors to monitor the movement of thousands of cell phones. Privacy advocates are concerned about a technology that can track people. But transportation and technology leaders said the data gathered will remain anonymous.
The technology doesn't use GPS. Instead, it takes the signals that wireless phones send to towers and follows the movement of the phones from one tower to another.
That information is laid over highway maps to draw a grid of where phones are and how fast they're moving.
No reason given for this "anonymous" tracking. Got bucks to spend?
