摘要

提出了一种基于像素的图像内容认证和纠错水印算法。该算法有两个特点:一是针对基于混沌序列的图像加密算法存在安全性差、计算复杂的缺陷,提出了一种新的基于无替换采样的图像混沌加密算法。其次,组合映射技术的应用弥补了图像内容认证水印存在的空白。利用该方法,可以以像素为单位,以最小的嵌入容量和最大的信噪比对数字图像进行校正。通过8×8将图像分成块,在块上进行图像内容认证和纠错。在该方案中,混沌加密不仅保证了安全性,而且提高了纠错率。

A Watermark Algorithm for Image Content Authentication and Correcting Errors in Terms of Pixels
This paper proposes a watermark algorithm for image content authentication and correcting errors in terms of pixels. There are two characteristics: first, aiming at defects of poor safety and the complicated calculation which are exiting in image encryption algorithm based on chaotic sequences, a new image chaotic encryption algorithm based on sampling without replacement is put forward. Second, the application of combination mapping technique supplies a gap which is exiting in image content authentication watermark. Using the authentication, digital image can be corrected in terms of pixels, and with the minimum embedded capacity and the maximum SNR. The image is divided into blocks by 8×8, image content authentication and correcting errors is done on blocks. In the scheme, chaotic encryption not only ensures the safety, but also advances correcting rate.
