UNAUTHORIZED USE OF A COMPUTER

Unauthorized use of a computer statutes are related to computer trespass. Because unauthorized use of a computer is often the result of computer trespass, it is quite common that both offenses may be brought against an offender for a single criminal act.

Unauthorized use statutes are fairly popular and they may be found in 12 states. Such statutes seek to punish those who without authorization use a computer or computer services. Generally, there is not a great deal of divergence among the states and the two elements which must be present are the user’s knowledge that access is not authorized and actual access.

In some situations, such as with California, if a state has dealt directly with a particular category of computer crime within the context of a larger encompassing computer crime statute, we have included in our statutory analysis a cross reference to the relevant subsection of that state’s statute. We have denoted states that are also listed in our general computer crime statute section with a ‘*’.
