Technology has made it increasingly simple to watch people. Whenever you leave the house to go shopping, there's a good chance your on camera and nowadays you never know when you're being listened to while on the phone.

Just from browsing websites we get tracking cookies that are automatically installed onto our computers. Some companies even sell our information to 3rd parties. The illusion of privacy is not to be blamed on any one assailant because methods of this madness come in all different shapes and sizes.
