One study of 1,500 computer crimes established that most of them were committed by trusted computer users within businesses; persons with the requisite skills, knowledge, access, and resources.
Much of known computer crime has consisted of entering false data into computers, which is simpler and safer than the complex process of writing a program to change data already in the computer. With the advent of personal computers to manipulate information and access computers by telephone, increasing numbers of crimes--mostly simple but costly electronic trespassing,
