The disclosed embodiments provide for checking documents for security compliance when the documents are printed, scanned, or copied. A security status is determined based on security indicators within a document's content. Security indicators can be located within a document's text, figures, watermarks, security marks, and invisible marks. Security indicators can be found by comparing a document's content to a set of stored indicator descriptions. The indicators found are used to determine a document score and security responses are triggered based on the document score.
