摘要：Reversible data embedding is a technique widely used to embed secret data into a specific media, such as military or medical images. In the past, many researchers have applied this scheme to the vector quantization (VQ) compression technique; however, the hiding capacity remains low. This paper proposes a novel data embedding scheme with reversibility for VQ compressed images. From our experimental results, we can confirm that the proposed scheme increases the hiding capacity and maintains high bit rates. Also, the VQ compressed images can be completely restored after extracting the embedded secret data. ? 2009 IEEE.
