A new method of data hiding based on H.264 encoded video sequences

Data hiding is a type of information hiding technology. A data hiding method based on H.264 encoded video sequences is presented in this paper. The proposed method uses the parity of the coefficients after transformation and quantization to hide the desirable data. The digital data hidden by this approach can be recovered correctly by data recovering process and extracted directly from the encoded stream without using the original host video. Experimental results demonstrate that the proposed method can obtain good performance.
