摘要

In this paper, it proposes digital watermarking algorithm that can protect copy right of an image by using contour extract techniques. In an image, the area where the number of contour has very complicated images can insert a large amount of watermark, which results in satisfaction of firmness and non-visibility of watermark. In addition, the information of watermark converts a copy of owner's information to ASCII code and by using converted ASCII code to binary code of 8 bytes, it does not concern similarity between watermarks in case of their distinction. Also, it suggests watermarking algorithm that does not require an original image and information of an inserted watermark.
