Since technology changes so rapidly, new legislation with respect to computer crimes often lags behind. But most states have at least addressed the issue, whether it's using encryption to commit a crime, introducing a computer virus, or some other cyber crime.
Illinois computer crime laws differentiate between misdemeanor computer crimes (sending spam, for instance) and felony computer crimes (such as financial fraud). Let's explore these in a little more detail.
Illinois Computer Crime Prevention Law
One way the state battles computer crimes is through the Illinois "Computer Crime Prevention Law" (ICCPL), which makes unauthorized computer use a criminal offense. The law is broken down into three (3) major categories.
- Computer Tampering: This includes gaining access to a computer, a program, or data, without permission from the owner and creating or distributing computer viruses.
- Aggravated Computer Tampering: This crime pertains to the government specifically. You can be in violation of the law if you tamper with a computer and you have the intended effect of: (a) disruption of or interference with vital services or operations of State or local government or a public utility, or (b) creating a strong probability of death or great bodily harm to other individuals.
- Computer Fraud: This crime pertains specifically to using a computer for fraudulent activities.
The key provisions of Illinois computer crime laws are listed in the table below.
