| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes an digital watermark method using extended smear-desmearing transform and high-pass filter.In this method, the signature information is diffused throughout the series by the complex smear-desmearing transform, which makes it difficult to identify the signature information by third parties.In addition, extended smear-desmearing transform expand the series. Therefore, signature information that can be embedded increases.Then, by using high-pass filter, has become signature can be detected for the compressed image.Finally, the computational experiments, to evaluate the image quality, the amount of signature information, the resistance to compression, we show the effectiveness of the method. | |
