SYSTEMS AND METHODS FOR TRACING THE SOURCE OF PRINTED PAGES |
摘要 |
Methods and systems are provided for tracing the source of a printed document. A method may include receiving a print job for printing a page having page content, generating a log of the print job, encoding the log using a mule image to produce a data-bearing halftone image, merging the data-bearing halftone image with the page content, and printing the merged data-bearing halftone image and page content to produce a printed document. |
