I had a contact inside the NSA who said the government can use the camera on your pc to record what your face looks like but they wouldn't even need that if you post pics of yourself on the internet or if they are on your pc. There is more no privacy and did you know the government has said that they would respect your right to privacy but that does not mean they don't know stuff about you that you hold so dear.
Also look on the back of your calculator if you have one here what is says:
