Wired News: Nike IPod = Surveillance: "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.
He brought his concerns to University of Washington computer science professor Yoshi Kohno and fellow graduate students Carl Hartung and Jonathan Lester. After just a few weeks of tinkering, the four researchers discovered that the Nike iPod is, as Kohno put it, 'an easy surveillance device.'"
