Abstract
A method for embedding 'no-scan' or 'no-copy' information in a document border includes encoding information as a plurality of data carrying dot pair patterns. For each page of a document to be rendered, the method includes determining whether the border area is blank. If found not blank the border area is cleared. Each of the plurality of data carrying dot patterns is embedded in the blank border area of the document page. The document page with the embedded data carrying dot patterns is then rendered, where each data carrying dot is too small to be visually noticeable.
