N2 - Information systems still have security gaps at their analog output interfaces printing confidential information. Digital watermarking for binary image can be used for tracking a paper even if it has been photocopied. We clarify the technical requirement for print traceability systems and propose the basic concept of the system framework Potential print traceability systems are categorized according to the identifiers that are embedded in the contents and that specify WHO, WHAT, WHICH, WHERE, WHEN, WHY or HOW. Our prototype system demonstrates that these traceability applications are ready for practical use.
