| 摘 要： | 脆弱性数字水印技术主要用于检测图像内容的完整性，即检测是否被篡改，并对其进行定位，它是解决数字产品内容保护的有效方法，而自嵌入水印技术不但具有检测篡改的能力，而且能够对被篡改区域进行修复，作者在对现有的自嵌入脆弱性水印进行分析的基础上，提出了一种改进的具有修复功能的自嵌入水印算法，大量的实验结果表明该方法的有效性与实用性。

| Abstract: | Fragile watermarking is designed to ensure the integrity of images,i.e.,it can detect any change to an image and locate the areas that have been tampered.It has been considered as an effective solution to protect the content of images.In this paper, we propose an improved technique for selfembedding an image into itself as a means for protecting the image content after analyzing other selfembedding methods. With selfembedding ,it is possible to recover portions of the image which has been tampered.This method has many advantages compared to other's and is testified by many pictures. |
