In a world such as the one created in George Orwell's novel, 1984, people are stripped away of one of their many, normally essential, human rights.
Privacy.
Something we take for granted, privacy is a luxury that people like Winston cannot afford to have. With danger lurking around every corner, this novel's protagonist is forced to hide himself, to do simple things such as write in a diary. What kind of world must that be, although only fictional, that you have no right to have your own opinions or thoughts? And with the amount of forecasting this novel gives, is this idea of complete openness so far-fetched? In our near future, maybe our rights will be taken away, leaving us as complete slaves to society.
The security cameras you see everywhere, should do anything but make you feel secure. After all, it could be Big Brother watching you. And who knows, maybe it will be your door that the Thought Police knock on next.
