Abstract

In the past several years, there has been an explosive growth in digital imaging technology and applications. Since digital images and video are now widely distributed via the Internet and various public channels, there is an urgent need for copyright protection against unauthorized data reproduction. Digital watermarking is an effective and popular technique for discouraging illegal copying and distribution of copyrighted digital image information. Furthermore, it can also provide an alternative solution for image authentication. A robust watermarking and image authentication technique is proposed. The proposed scheme includes two parts. The first is a robust watermarking scheme performed in the frequency domain, which can be used to prove the ownership. The second is a standard signature process, which can be used to prove the integrity of the image. The input of the signature process is the edge properties extracted from the image. The signature can be correctly verified when the image is incidentally damaged such as lossy compression.

一种鲁棒的水印和图像认证技术

在过去的几年里，数字成像技术和应用有了爆炸式的增长。由于数字图像和视频现在通过互联网和各种公共渠道广泛传播，因此迫切需要保护版权，防止未经授权的数据复制。数字水印是防止非法复制和传播受版权保护的数字图像信息的一种有效和流行的技术。此外，它还可以为图像身份验证提供另一种解决方案。提出了一种鲁棒水印和图像认证技术。该方案包括两个部分。首先是在频域执行的鲁棒水印方案，该方案可用于证明所有权。二是标准的签名过程，可以用来证明图像的完整性。签名过程的输入是从图像中提取的边缘属性。当图像偶然损坏(如有损压缩)时，可以正确地验证签名。
