The present invention is a system for utilizing a printable, yet unobtrusive glyph or similar two-dimensionally encoded mark to identify copyrighted documents. Upon attempting to reproduce such a document, the glyph is detected by a detector (30), decoded by a decoder (34) and used to accurately collect and/or record a copyright royalty for the reproduction of the document, or to prevent such reproduction. Furthermore, the glyph may also include additional information so as to enable an electronic copyright royalty accounting system, capable of interpreting the encoded information, to track and/or account for copyright royalties which accrue during reproduction of all or portions of the original document.

Title
