基于线性码理论的可验证图像信息隐藏方案

Verifiable Image Information Hiding Scheme Based on Linear Code Theory

提出了一种将图像本身作为秘密信息的安全传输方案。该方案从图像中提取像素矩阵,依靠相应的序列生成算法,得到多个同型矩阵,并将其作为原秘密图像信息的载体进行传输;接收方将收到的多个矩阵信息代入对应方程组并求解,并利用线性码理论验证无误后,即可恢复原秘密图像的像素矩阵,进而复原出原秘密图像。该方案避免了直接的图像压缩编码,是一种致力于安全、可靠传输图像信息并将图像信息隐藏的新思路。

A secure transmission scheme that uses the image itself as secret information is proposed. The scheme extracts the pixel matrix from the image, and obtains multiple homomorphic matrices by means of the corresponding sequence generation algorithm, and transmits it as the carrier of the original secret image information. The receiver substitutes the received matrix information into the corresponding equations and solves it, and after verifying the error by the linear code theory, the pixel matrix of the original secret image can be restored, and the original secret image is restored. This scheme avoids direct image compression coding and it is a new idea for safely and reliably transmitting image information and hiding image information.
