Abstract

Fragile watermarking schemes are very common in practice for tamper detection and image authentication. In this paper, we propose a new fragile watermarking scheme to detect common image tampering operations such as copy and paste attack and image splicing attack from color images. The proposed scheme is intended to do the watermarking with an image dependent authentication code during color image demosaicking procedure. We propose a new method to generate almost unique authentication code from an image by comparing RGB color components of the pixels. In the proposed scheme, every pixel will be watermarked with an encrypted authentication code derived from the same pixel. To embed the watermark a new method has been proposed in this paper, where the color filter array sampled components will not be considered during watermarking, and only the rebuilt color component values of every pixel will be modified according to the authentication code. The experimental study shows that the proposed watermarking scheme produces images with better visual quality as compared to the state-of-the-art, and is capable of detecting both copy and paste attacks and image splicing attacks more accurately than the existing schemes.

基于上下文的彩色图像篡改检测脆弱水印方案
脆弱水印方案在篡改检测和图像认证中非常常见。本文提出了一种新的脆弱水印方案,用于检测彩色图像中常见的复制粘贴攻击和图像拼接攻击等图像篡改行为。该方案旨在在彩色图像去马赛克过程中使用与图像相关的认证码进行水印。我们提出了一种新的方法,通过比较像素的RGB颜色成分,从图像中生成几乎唯一的认证码。在该方案中,每个像素都将使用从同一像素派生的加密认证码进行水印。为了嵌入水印,本文提出了一种新的方法,该方法在水印过程中不考虑颜色滤波器阵列的采样分量,只根据认证码修改每个像素的重建颜色分量值。实验研究表明,与现有的水印方案相比,所提出的水印方案产生的图像具有更好的视觉质量,并且能够比现有方案更准确地检测复制粘贴攻击和图像拼接攻击。
