A Predictive Coding Information Hiding Algorithm with Large Capacity Based on Image Separation
In view of the information security questions, the information hiding technology already becomes the hot spot in the research field. On the basis of the predictive coding, a reversible information hiding algorithm is proposed. In the algorithm, the carrier image is divided into embedding separations and non-embedding separations of secret information to restrain the error diffusion which possibly happens when decoding. This makes the original carrier image can be restored absolutely when extracting the secret information. As a result of the experiments on the carrier image of different sizes, the algorithm has achieved large information hiding capacity of 0.9S3 bits/Byte and PSNR of 49.184dB. And the validity of this algorithm is proved.
