The infringement of the copyright is a problem by the distribution of digital contents copied illegally. The digital watermark is expected as a thing preventing unjust copying by burying information in digital data such as image, animation, the sound, TV, radio and movies.

If a computer cannot recognize the information reproduced from digital watermarking, the information does not have a meaning.
