Well: What would have been an authoritarian state's dream is todays reality. It is widely known that the
NSA listens to phonecalls of virtually anybody on the planet. Very worrying.
Even more worrying is that
every photo you take with a digital camera gets an identifying mark of a unique camera and already longer than 10 years
printers mark papers that can link every sheet of paper back to the printer it was printed on.
In my country there are camera's on every highway, registering -and keeping- all car-traffic. Even worse; soon I can't buy a public transport ticket that is not registered to my name via a creditcard, or personalised buspass. All that information is stored, meaning I cannot go anywhere outside bike-distance without a governmental institution knowing where I am.
Do you really think this is only to catch child-porn creators? Do you really think this is to catch counterfeiters? Do you really think this is to fight terrorism?
Do you really think a state that wants to control its citizens and does not tolerate anti-government voices to be heard demands HP to only sell printers in their country that always makes prints identifyable ?? Dissidents are easily caught with this.
This technology is not fiction. This technology exists. This technology is being used. This is technology that can so easily be used to control the citizens of a nation. This technology is East-Germany's dream - only 15 years after Communism fell, the West is under more surveilance than the East-Germans were.
You can trust your government to not do it, sure, but when you do, think of this: This technology will not go away. In order to not share my fears, you will have to trust the government for 50 years. For 100 years. For ever. I don't trust my goverment that they will not use an existing powerful technology in this way.
