“Healey proposes using GPS to protect abuse victims, gang crime witnesses/a” however brings immediately to the forefront the kind of action that I foresaw the global positioning system being used for when I first read the above article. The same risks are of course built in to the OnStar™ system. We do not want to give Government this sort of control over our lives. We do not want to trust government to sufficiently obscure the signals being used so that only the government can track us. Remember the lack of privacy in “Minority Report”? The potienal for being tracked? The difficulty in changing your “key” when it is a biometric? GPS systems are not quite so bad, you can ditch a device afterall. But the same sort of risks are there. The system that lets a government track a criminal lets businesses and, as technology grows cheaper and more prevelent, eventually individuals track track him also. And as people grow accusomed to tracking each other, eventually all of us. The California article is one way this will come to be, all of us being tracked to tax our milage. The RFID concerns documented well by EPIC/a and EFF/a represents another avenue for pervasive survalence to enter our lives.
