Cell phones had become so personal that detecting them on the street means to detect the owners. By using the information of the phone along with its GPS position it is possible to record and analyze the behavioral patterns of the people in the street. Bluetooth devices are ubiquitous, but until recently, there were no tools to perform bluetooth wardriving with GPS position and behavioral analysis. A new tool called Bluedriving is presented for doing this type of bluetooth wardriving. Also, most people is not aware that their bluetooth device allows to abuse their privacy. The bludriving tool can visualize the devices on a map and set different alerts to follow people in the street. The tool is presented along with a large capture dataset and a deep privacy analysis. We conclude that it is possible to follow people in the street by detecting their bluetooth device.
