Abstract :
This paper presents a new VQ(vector quantization) -based reversible data hiding scheme using multi-extended codebooks. The algorithm has large capacity, high PSNR. It can also extract secret data completely without the participation of original image. Since the new method of codebook classification, the proposed algorithm transmits less information in order to extract the secret data and has simple computational complexity. Additionally, more secret data can be embedded, because that all the codebooks are used to embed information.
