| 摘 要： | Fragile watermarking is a method to verify the integrity and authenticity of multimedia data. A new fragile watermark for image was proposed, which can be used in image verification applications. The paper first described the above two techniques, some of which will be used in the method. Then it described the embedding and authentication process and also analyzed the method to show how it can survive some attacks. The experimental results show that the proposed method doesn‘t need the watermark or original image on authentication side. It provides more security against attack, and can localize where the temoerinlz has occurred.

It provides more security against attack, and can localize where the tempering has occurred. |
