The concept of protecting information from unauthorized disclosure is:

The concept of protecting information from unauthorized disclosure is most closely associated with confidentiality. Confidentiality refers specifically to the obligation of individuals and organizations to safeguard personal information, ensuring that it is accessed only by those who are authorized to view it. This is especially crucial in health information management, where sensitive patient data must be shielded from exposure to unauthorized parties.

While privacy encompasses the broader idea of individuals having control over their personal information and how it is used, confidentiality zeroes in on the mechanisms and responsibilities involved in maintaining secrecy and preventing unauthorized access. Security, on the other hand, pertains to the technological and administrative measures implemented to protect information systems and data from breaches, which supports confidentiality but isn't focused solely on the concept of unauthorized disclosure. Ethics, while integral to guiding decision-making around information handling, does not specifically address the act of protecting information itself.

Therefore, the emphasis on safeguarding against unauthorized access and ensuring that only permitted individuals can view specific information indicates that confidentiality is the most appropriate term in this context.
