Confidentiality refers to the practice of keeping sensitive information private and secure. It ensures that personal data, such as medical records or financial details, is only accessible to authorized individuals. This principle is crucial in various fields, including healthcare, law, and business, to protect individuals' rights and maintain trust. Maintaining confidentiality involves implementing policies and procedures that limit access to information. For example, professionals like doctors and lawyers are often required to follow strict guidelines to safeguard their clients' information. Breaching confidentiality can lead to legal consequences and damage relationships between parties.
