What does the classification concept apply to when discussing "Revealed by"?

The concept of "Revealed by" in derivative classification specifically pertains to situations where information is presented in a different form, such as through paraphrasing or restating. This includes any instance where classified information is conveyed or inferred even if it is not shared verbatim.

When information is paraphrased or restated, the classified nature of the original source can still be disclosed, necessitating careful consideration of how that information is handled, classified, and shared. This reinforces the importance of managing the classification status of not just direct quotes but also the ideas and concepts derived from classified material.

In contrast, focusing solely on high-level classified documents, limiting the application to specific formats like emails or verbal communications, or assuming it doesn't apply universally to all types of information sharing misses the broader implications of derivative classification. The correct understanding emphasizes that any form of information that interacts with classified content—regardless of its original format or level—requires diligence in maintaining security and proper classification.
