California Computer Crime Laws

California state laws include provisions intended to protect the computers, computer systems, and computer networks of individuals, businesses, and organizations across the state. California criminalizes many computer-related activities that affect the functionality, use, or confidentiality of computer data, computers, computer systems, and computer networks.

An individual who accesses a computer, computer system, or computer network and alters, disrupts, deletes, destroys, or otherwise changes any part may be charged with a computer crime. The applicable type of computer crime depends on the defendant's purpose for engaging in the unlawful access. For example, a prosecutor may need to show that the defendant wanted to execute a plan for deception, fraud, or extortion, or to take control of information, money, or property that did not belong to the defendant.

Other computer crimes focus on access made to introduce a computer virus or contaminant for harmful purposes.

In addition, California state laws criminalize the unauthorized taking or copying of data and information from a computer, computer system, or computer network. For example, this type of computer crime might apply to an individual who takes computerized business records from an organization or an employee who copies work product from an employer's computer network without permission.

Knowledge Requirement

For each computer crime, a prosecutor must prove that the defendant "knowingly" engaged in the computer-related act. If the defendant performed the act accidentally, it may be more difficult to establish the elements of the charged crime. In addition, a prosecutor must show that the defendant acted without permission or authorization.
