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 instead of just using the MAC directly?" The same is done for ANPR based systems. The word "encrypted" seems to be added to some how make it secure without the solution being secure.
