Abstract

An adaptive and large capacity steganography method applicable to compressed video is proposed. Unlike still images, video steganography technology must meet the real-time requirement. In this work, embedding and detection are both done entirely in the variable length code (VLC) domain with no need for full or even partial decompression. Also, embedding is guided by several so-called A/S trees adaptively. All of the A/S trees are generated from the main VLC table given in the ISO/IEC13818-2:1995 standard. Experimental results verify the excellent performance of the proposed scheme.
