Cross-Domain Using Composing of Selected DCT Coefficients Strategy with Quantization Tables for Reversible Data Hiding in JPEG Image

Abstract

Reversible data hiding (RDH) techniques for JPEG images have big challenges in order to improve the capacity, quality, and flexible embedding method. In this paper, we propose a new RDH algorithm using combination of selected DCT coefficients strategy with quantization tables. In order to further reduce the distortion, we survey the effect of quantized process on DCT coefficients for making the strategy of selection the embedding DCT coefficients. Compared to the conventional method, our experimental results show that our proposed method has better performance in terms of both the increasing capacity and improving the quality of embedded JPEG images after data embedding.KeywordsReversible data hiding (RDH)JPEG imageDC coefficientsAC coefficientsQuantization tables
