| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | E-book that can read on your computer or mobile device began to come into wide use in the market. The comics have been digitized as well as the novels. There are also various types of image posting sites on the Internet. It has also been posted by amateur painters. Furthermore, comics are sometimes created on PC and some professional painter have created in that way. Digital data can be copy，save，and processed easily. And you can trace easily by using the painting program．So some digital contents may be exploited against the willing of the copyright holder. Watermarking techniques are studied to solve such problems. Most of watermarking methods are not suitable for the cartoons and the illustrations with bilevel lines． As the illustrations such as cartoons are consist of bi-level lines, it is difficult to embedding the required information while keeping the quality of the original illustrations. The information embedded into the hand writing trace is hard to decode with conventional methods which embed the information into the value of the pixels directly. To solve these problems, we propose a watermarking implementation for the bi-level traced images which embeds the watermark into the bezier curves which compose the illustration. We will not be able to recover the information in the existing methods of embedding the information in the pixel value． |
