摘要
提出一种以线性码原理和混沌映射理论为基础的无载体信息隐藏方案。通过提取图像的像素矩阵,利用线性码原理和混沌映射理论先后对矩阵信息作可验证处理和加密处理,最后通过一系列变换建立图像与密文信息的对应关系,从而实现无载体信息隐藏。实验和分析表明,该方案保证了信息的安全性,增强了随机性,同时具有可验证性,这使得提出的信息隐藏方案是可信任的。另外相比于其他方案,该方案的隐藏容量有了很大的提升,并且大大减少了信息库的存储资源消耗。
An coverless information hiding scheme based on linear code principle and chaotic mapping theory is proposed.The scheme extracted the pixel matrix of the images,and used the linear code check principle and the chaotic mapping theory to verify the matrix information and then encrypt them.The correspondence between the images and the ciphertext information was established through a series of transformation,thus the coverless information hiding scheme was realized.Experiments and analysis show that this scheme guarantees the security of information,enhances randomness,and is verifiable,which makes the proposed information hiding scheme trustworthy.In addition,compared with other schemes,the hidden capacity of this scheme has been greatly improved,and the storage resource consumption of the information base is greatly reduced.
