Confidential documents are papers that contain sensitive information that should not be shared with the public. This can include personal data, business secrets, or government information. Keeping these documents secure is important to protect privacy and maintain trust. For example, medical records and financial statements are often classified as confidential because they contain private details about individuals. Organizations use various methods to safeguard confidential documents, such as encryption and restricted access. Employees may need to sign a non-disclosure agreement (NDA) to ensure they do not share this information. By protecting these documents, companies and individuals can prevent misuse and maintain confidentiality.
