Reversible Data Hiding Techniques for VQ-Compressed Domain

Data hiding is designed to solve the problem of secure information exchange through networks such as Internet. In that, reversible data hiding is the good technique for recovering original images without any distortion after secret data are extracted from the stego image. This technique continues to attract attention from many researchers. In this work, three reversible data hiding schemes are proposed to embed secret data into the VQ and SMVQ compressed image.
