Can someone spy every one of our movements?

Privacy is a vital part of our lives. We all have the right to our privacy, but how would it be like if our everyday life was like the lives these celebrities confront to stay on the Big Brother show? Not so pleasent. The Big Brother concept can't happen in real life because it's illegal unless you agree with it. If it has already hsppened is because it was some type of psycho stalking you, which has happened, for example in the Maury show, there has been some shows focused on people who have been stalked, in most cases by men. A study by the National Institute of justice found that 8% of American women and 2% of American men are stalked, meaning 1.4 million Americans are stalking victims every year. So i believe that the only way someone will spy on you is if they're stalking you or if the person has committed a minor crime and the government has the right to watch over their actions.
