Abstract:
In an information processing device which embeds a number of partial information items produced from predetermined information in an image, an image dividing unit divides an image into a number of division images in a lattice formation to generate the division images. An information assigning unit assigns the partial information items to the division images generated by the image dividing unit. An information embedding unit embeds the partial information items assigned by the information assigning unit, in the division images. The information assigning unit assigns all the partial information items to a set of division images located in a predetermined direction.
