If an information pattern is identified, the extracted information can be used effectively. Moreover, it is possible to enhance the information embedding efficiency.

Abstract: A PC generating image data divides data to be embedded into a predetermined size and arranges it in a predetermined area of a watermarking image. In the predetermined area are defined positions a-h assumed by an information dot configuring an information pattern based on the data to be embedded, and, of positions a-h, a position defined for the information pattern is assumed by a point dot. Of positions a-h, a position that is not defined for the information pattern is assumed by a linear dot.

The linear dot has a geometry extending in one of the main scanning direction and vertical scanning direction of an image formation apparatus that allows higher performance in reproducibility for a line.
