摘要

提出了一种无损数据隐藏的图像篡改检测方法。该方法将数据嵌入到图像中,并在空间域中从图像中提取数据。该方法在还原原始图像的同时,从传递隐藏数据的图像中提取隐藏数据。该方法使用且只有一个参数来控制图像的嵌入和提取。将图像分成若干块,并将块的图像特征描述隐藏到相应的块中。将从图像中提取的隐藏描述与从恢复图像中生成的隐藏描述进行比较以检测篡改。具有隐藏数据的图像的图像质量很高,因此没有人意识到数据被隐藏了。实验结果表明了该方法的有效性

Lossless Data Hiding in the Spatial Domain for Image Tamper Detection
This paper proposes lossless data hiding method for image tamper detection. The proposed method embeds data in images and extracts data from images in the spatial domain. This method restores the original image as well as extracts hidden data from an image conveying hidden data. The proposed method uses one and only one parameter for each image to control embed and extract data. An image is divided into several blocks, and the image feature description for the block is hidden into the corresponding block itself. Hidden descriptions extracted from an image and generated from the recovered image are compared to detect tampering. The image quality of an image with hidden data is high so that nobody is aware that data are hidden. Experimental results show the effectiveness of the proposed method
