From the article: If you enhance your workout with the new Nike+ iPod Sport Kit, you may be making yourself a surveillance target.
A report from four University of Washington researchers to be released Thursday reveals that security flaws in the new RFID-powered device from Nike and Apple make it easy for tech-savvy stalkers, thieves and corporations to track your movements. With just a few hundred dollars and a little know-how, someone could even plot your running routes on a Google map without your knowledge.
The Nike+ iPod gives runners real-time updates about the speed and length of their workouts via a small RFID device that fits into the soles of Nike shoes, and broadcasts workout data to a small receiver plugged into an iPod Nano.
While this setup sounds convenient and cool, it didn't sit well with Scott Saponas, a computer science graduate student at the University of Washington in Seattle. After enjoying his Nike+ iPod for a few months, Saponas began to suspect there might be other, more nefarious uses for the gear.
