摘要：
A first encoder splits an image into a plurality of blocks, and embeds a first data into the image based on a difference between feature amounts in a combination of the blocks. A second encoder encodes a second data in a form of a combination of image patterns. A disposing unit disposes the combination of image patterns in the image in which the data is embedded by the first encoder.
