%X 本文提出了一种新型的利用信息隐藏技术进行图像保护的方案。在该方案中，我们从原始图像中选取一些像素组成信息图像，并将未被选中的像素点构成的图像称之为剩余图像。对信息图像中像素点的离散余弦变换结果进行量化和编码，再将得到的码流压缩后的结果嵌入到缩略图中。最后，将嵌入数据的缩略图在公开信道中传输。在接收端，具有权限的接收者可以在预览缩略图后使用密钥重建原始图像。在仿真实验中，重建图像的PSNR值达到了40 dB，这表明我们的方法具有较低的图像失真率。此外，文中所提出的方法可以实现高数据压缩率和低运行时间。<br />
This study proposes a new type of copyright protection scheme using information hiding technology. In the scheme, we select some pixels from the original image to form an information image, and a thumbnail of the original image is composed of the residual pixels. Quantizing and encoding the result of the discrete cosine transform (DCT) of the pixels in the information image, then obtained code stream is compressed and embedded in the thumbnail. Finally, the thumbnail with embedded data is transmitted in public channel. And recipients with permission can reconstruct the original image using the key after previewing the image. In the simulation experiment, the PSNR value of restored image reached 40 dB which shows that our method can improve the image quality. Besides, the proposed method can achieve high data compression rate and low running time.
