一种验证JPEG图象内容完整性的自恢复水印技术

A New Fragile Watermark with Self-Correcting Based on JPEG Image

自嵌入水印技术是将图象本身作为水印嵌入到图象中的水印技术,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。现在的自嵌入水印技术大多比较脆弱,特别是在抗JPEG压缩方面显得过于脆弱,因此在实用性方面受到一定限制。提出了一种直接对JPEG图象进行自嵌入的数字水印算法,实验结果表明该方法的有效性与实用性。

self-embedding watermark technology to regard itself of vision as watermark embed watermark technology to reach vision by oneself,not only measure the ability to distort but also can repair in the area to distorting.Since the current self-embedding watermarking techniques are too fragile to resist noise or JPEG compression,so sure to limit in practicability.This paper proposes a self-embedding method that embed to JPEG vision directly,the experimental result shows the validity and practicability of this method.
