What concept involves holding information in trust and not disclosing it without proper authority?

The concept described is confidentiality, which refers specifically to the obligation to protect and manage information with discretion and to refrain from disclosing it without appropriate authorization. This concept plays a crucial role in various fields, such as healthcare, law, and business, where sensitive information is involved. Adhering to confidentiality ensures that personal and private information is safeguarded, fostering trust between individuals and organizations.

Trustworthiness, while related, emphasizes the reliability and dependability of an individual rather than the specific management of sensitive information. Integrity refers to adherence to moral and ethical principles but does not specifically address the handling of confidential information. Ethics encompasses broader principles governing conduct but does not focus solely on the confidentiality of information. Therefore, confidentiality is the most accurate term for the practice of withholding information without proper authority.
