The Big Brother State [website]
“The Big Brother State is a short educational film created at the German university of Augsburg which tries to provide a different view of certain laws that are supposed to protect our freedom for the sake of our rights and privacy. Do we really need more observation at public places, trusted computing, biometric passports and network traffic monitoring. Who is able to tell that that no misuse will ever happen with the collected data ?”
