Since the invention of the telephone, communicating with people who live in the opposite part of the earth is no longer an impossible mission. The telephone is no doubt a great invention, but it is also a double-sided sword. When the telephone offer us advantage and convenient service, people with bad purposes take advantage of the convenience to cheat phone users by changing caller id. It makes many phone users feel terrified and start to doubt every incoming call. Users even think that the best way to guard against cheating is never answering the phone with unfamiliar caller id.
