Which term describes the act of using information obtained for non-official purposes?

The term "Misuse of Information" accurately describes the act of using information obtained for non-official purposes. This concept refers to the inappropriate or unethical use of information, which includes utilizing sensitive or classified data for personal gain or any purpose not sanctioned by the organization or entity that owns the data. Misuse implies a violation of trust and ethics, indicating that the individual has overstepped boundaries set for the handling of information.

While other terms like "Illegal Information Use" and "Unauthorized Information Access" also address aspects of improper information handling or privacy violations, they have more specific connotations. "Illegal Information Use" suggests that the usage is against the law, which encompasses a broader context beyond just non-official purposes, while "Unauthorized Information Access" focuses on the act of gaining access to information without permission, rather than how that information is subsequently used. "Information Abuse" could imply a broader range of misconduct but does not specifically emphasize the non-official aspect as clearly as "Misuse of Information." Thus, the first term captures the essence of the situation succinctly and accurately.
