| 摘要 | There is an increasing number of products to be saved in digital form. In the digital world, we can preserve products forever, but there are also disadvantages such as easy copying. The watermark is an important protection method in digital media. When a media is publicly available or put on a network, it is very easy to copy or be misappropriated. The author can prove ownership by using an open algorithm and security key to extract the watermark. Therefore, a watermark technique must resist attacks and cannot influence image quality. We propose an image watermark technique based on the spatial domain in a color image. We present experimental results which prove that our method can resist certain attacks. |
