| 摘 要： | 本文基于JPEG有损压缩提出了一种半脆弱性数字图像水印算法。实验测试表明,所提出的算法不会明显影响图像的主客观质量,对JPEG有损压缩具有一定的顽健性,可以有效地进行篡改检测,达到检测和标示图像内容真实性的目的。

| Abstract: | With the rapid growth of network, the authentication for digital information has attracted much scientific and commercial attention. A novel semi-fragile digital image watermarking algorithm, which is based on JPEG lossy compression, is proposed in this paper. Simulation experiments prove that it will not degrade the objective and subjective quality of original images, and robustness is showed to JPEG lossy compression. The scheme can be used to the detection of manipulation and image content authentication verification. |
