Abstract

A digital watermark (100) comprises of various techniques for encoding hidden information in checks and other security documents. The hidden information provides an authentication tool. Also including a method for encoding a security document with information. The security document comprises a substrate (102) having printing thereon. The information is hidden in the printing and corresponds to text or numbers conveyed by at least a portion of the printing. The method includes dividing the information into a plurality of playload sets, wherein each payload set includes a sub-set of the information, and encoding the payload sets acoss the substrate (102). The plurality of payload sets is concatenated in order to retrieve the information.
