"Private (Confidential)" refers to information that is intended to be kept secret and not shared with unauthorized individuals. This type of information can include personal data, business secrets, or sensitive communications. The goal of confidentiality is to protect the privacy and security of the information and the individuals or organizations involved.
In many contexts, such as in legal, medical, or corporate settings, confidentiality is governed by laws and regulations. For example, HIPAA in the United States protects the privacy of patient information, while non-disclosure agreements (NDAs) are often used in business to safeguard proprietary information.
