Design of steganography algorithm based on MPEG-4 coding scheme

An information hiding algorithm based on MPEG-4 texture coding was proposed. Hiding information in VOP motion texture codes could be realized by replacing the YUV value of non-VOP pixels in the DCT coding block with secret data, and modifying the transparence of the VOP. It was proved by the experim...
