Abstract
The invention disclosed here is a method of encoding serial numbers indicating 'confidentiality' or 'proprietary information' on printed documents. A group of marks in the form of small-sized dots or equivalent markings are repetitively printed across the face of the document. The placement and location of the markings defines a readable binary serial number. Intermixing the markings with the printed matter on the document makes it difficult or impossible to remove the serial number created by the markings, and they will remain on the document after repeated photocopies of it are made.
