What does declassification refer to?

Declassification specifically refers to the process of changing information from classified to unclassified status. This process is crucial for ensuring that sensitive information is handled appropriately and that any information no longer deemed sensitive can be shared with the public or other entities without compromising security. Declassification can occur due to various reasons, such as the information becoming outdated, the expiration of a classification review period, or changes in national security interests.

When information is declassified, it must go through a formal review process to ensure that no residual sensitive content remains that could still pose a risk if disclosed. This is important for maintaining the integrity of the classification system and ensuring that only truly sensitive information remains classified.

In contrast, changing the classification level of information simply modifies its existing status, but it does not equate to declassification. Permanent destruction of classified information involves eliminating the information from existence and does not relate to its status change. Similarly, transferring classified information to other departments involves moving sensitive data without altering its classification status, which also differs from the concept of declassification.
