The Computer Misuse Act 1990 (c. 18) is an act of the Parliament of the United Kingdom. It was made after Robert Schifreen and Stephen Gold hacked into British Telecom's Prestel viewdata service in 1984-1985. They were even able to see personal messages of Prince Philip, but they could not be prosecuted as there were no laws against hacking. This was a problem, as people could hack into systems and see personal data without breaking the law, which was why the Computer Misuse Act was made.
