ABSTRACT

In this paper, a novel deblocking filtering-based VP8 steganographic scheme is proposed. The unique aspect of this work and one that distinguishes it from the prior art is that we effectively exploit the characteristics of deblocking filtering. We propose to embed the secret messages by comparing the quantized discrete cosine transform coefficients before and after the in-loop filtering. In the process of encoding, given one frame, first, we encode it to obtain the quantized discrete cosine transform coefficients. Second, a new set of coefficients is obtained by re-encoding the filtered frame. Third, the distortion function is defined by comparing the difference between the two sets of coefficients. Finally, adaptive embedding is realized by using the syndrome-trellis codes. Experimental results show that satisfactory levels of visual quality and steganographic security could be achieved with adequate payloads.
