Well put! Confidentiality is a conditional pause on release of information. But it will be revealed when an imminent threat to National Security is resolved. Good point there!
Confidentiality is the practice of keeping sensitive or private information entrusted to an individual, organization or professional, private and secure from unauthorized individuals. It includes protecting information from being accessed, disclosed, or shared without the consent or knowledge of its owner. Confidentiality is an essential aspect of many professions, such as healthcare and legal, where it is mandated by law to protect the privacy of their clients or patients. Failure to maintain confidentiality can result in various legal, ethical, and professional consequences.
So point you bought up.
Privacy - control over personal information.
Confidentiality- control over entrust information
Secrecy- information that no one should ever know.
