The concept of 'confidentiality' in encryption refers to the principle that only authorized users can access the data. This is achieved through encryption techniques that transform data into a format that is unreadable without the appropriate decryption key or credentials. By ensuring that only individuals or systems that have been explicitly granted permission are able to access the information, confidentiality safeguards sensitive data from unauthorized access, maintaining its privacy and security.

When data is shared openly among users, it contradicts the idea of confidentiality, as it could lead to unauthorized individuals gaining access to sensitive information. Additionally, securely backing up data is related to availability and integrity rather than confidentiality; it ensures data can be retrieved in case of loss rather than restricting access. Archiving data for future reference also does not pertain to confidentiality, as it simply involves storing data without necessarily controlling who can access it. Thus, maintaining confidentiality is crucial for protecting sensitive information from potential exposure to those who should not have access.
