What does the use of session locks ensure regarding visible information?

The use of session locks is primarily designed to enhance security by ensuring that previously visible information is concealed when a user becomes inactive or leaves their workstation unattended. This feature prevents unauthorized individuals from accessing sensitive data that may have been visible to the user before the session was locked. It is an important security measure that helps maintain the confidentiality and integrity of information by minimizing the risk of data exposure in environments where multiple individuals have physical access to the same workspace.

For clarity, visible information remaining unchanged, permanent deletion of information, or unrestricted access to all visible information do not align with the purpose of session locks, which focus on protecting displayed information from potential onlookers rather than modifying or deleting it outright.
