I work in the traffic industry and over the last 8 years I have seen the rise of WIFI and Bluetooth journey time monitoring kit and after looking at every solution, I have found that the method of "encrypting" the data has always been just a MD5 hash, or SHA if you are lucky. With with result Hash just been http'ed over to a server on the internet. This usually leads to to question, "OK, so I can just hash the victims MAC address and the look for that in the data stream to find out where the person is insteadvof just using the MAC directly?"
