The security printer unit prints the content and security identifier of the electronic document, and generates a secure printed document by applying a security material. The exit management server unit records and determines whether the secure printed document has been exited. The illegitimate exit detection unit detects the security material of the secure printed document, generates an exit warning, analyzes the security identifier, and determines whether the secure printed document is to be exited.
