What term is used to describe information that must be kept private and secure?

The term "confidential information" is used to describe information that must be kept private and secure. This designation emphasizes the importance of protecting sensitive data from unauthorized access or disclosure. Confidential information often pertains to personal or proprietary details that, if leaked, could harm individuals or organizations.

This term encompasses a wide range of data, such as personal identification details, financial records, trade secrets, and any other information that requires a level of secrecy to safeguard privacy and maintain trust. Maintaining the confidentiality of such information is crucial in various fields, including law enforcement, healthcare, and corporate environments.

In contrast, "public information" refers to data that is available to the general public and does not require protection, while "restricted information" typically applies to data that is not just confidential but also has specific access controls and is legally or institutionally designated as restricted. "Private data" is a more general term that may imply confidentiality but does not have the formal connotation of the protection standards associated with confidential information.
