Abstract:

This paper presents a reversible data hiding scheme based on dynamic reference pixel and multi-layer embedding.The proposed algorithm can offer very high embedding capacity and low image degradation,and the exact original cover image can be fully restored after the hidden data extracted without any error.Especially,different from previous works based on histogram shifting,the proposed scheme can recover the original cover image after data extraction with no extra information except the message length and the stego-image itself.Experiments have been conducted to show the effectiveness of the proposed method.

Key words: lossless data hiding, dynamic reference pixel, pixel difference histogram, histogram shifting
