Psst! Hey, buddy! Do you want to have a complete travel/movement database for your automobile-using populace but don’t have the scratch for a a bunch of high-tech, privacy-destroying surveillance copcars? Brazil has an idea for you!
An article published last week in ZeroHora notes the details of the implementation: a five-dollar chip to be installed on the windshield will contain details of the vehicle which are otherwise observable — registration, vehicle make, model, fuel used, and other identifying factors. No owner data may be stored on the chip and the chip can only be used for EZ-Pass-style toll collection “with consent of the owner”.
It’s difficult to conceive of any legitimate use of these tags other than to plant RFID receivers in public areas and obtain personal trip information. Note that I didn’t say “for the government to plant RFID receivers in public areas and obtain personal trip information.” The nature of RFID tagging is such that it can be read by anyone with the correct equipment. The whole project seems less appropriate to Brazil the country and more to Brazil the film.
