A novel, low complexity chaotic steganography method applicable to MPEG-2 videos is proposed. The security of this algorithm is based on the randomness of steganography location. One class of perturbed digital chaos is employed to generate pseudo random sequences with perfect statistical properties. In this work, the embedding and detection are both done entirely in the variable length code (VLC) domain, with no need for full or even partial decompression to meet the real-time requirement. Experimental results verify the availability of the proposed scheme. (4 pages)
