Which term refers to a legal tool for protecting certain information from being disclosed?

The term that refers to a legal tool for protecting certain information from being disclosed is privacy law. Privacy laws are designed to establish guidelines for the collection, storage, and sharing of personal information. They aim to protect individuals' rights to keep their personal information secure and confidential, ensuring that unauthorized parties cannot access or use this information without consent.

Privacy laws can cover various aspects, including healthcare information, financial records, and personal identification details. They create legal frameworks that organizations must follow to safeguard sensitive information, ultimately promoting transparency and accountability.

In comparison, security measures pertain more to the actions and protocols put in place to physically or digitally secure information rather than the legal protections surrounding it. Public law generally deals with issues that affect society as a whole, and civil law covers a broad area of non-criminal legal matters, focusing more on disputes between individuals or entities rather than the specific protection of information.
