Patent Images
1. A method for creating a watermark in a target document at different stages of the target document life cycle, the method comprising:
- scanning the target document containing a target watermark;
recovering the target watermark from the target document, the recovered target watermark indicating a template specification for describing how the watermark was merged into the target document;
generating an additional watermark according to a watermark specification;
updating the template specification by adding the watermark specification and associating the additional watermark with the watermark specification in the template specification; and
merging the generated watermark with the scanned target document.

Abstract
A multi-stage watermarking system and process that creates a watermark specification which describes how to generate a watermark, generates a template specification which describes how to merge the watermark into a target document, generates the watermark based on the watermark specification, and merges the watermark into the target document based on the template specification to provide a watermarked document.
