An efficient adaptive data hiding scheme for image steganography

Abstract

Steganography is crucial for maintaining integrity, authenticity, copyright protection, illegal use detection, and distribution of digital media over public networks. In this paper, a new adaptive steganography technique is proposed to provide better tradeoff between the two main conflicting parameters––capacity and robustness. An adaptive approach is exploited to decide about the required position and size of the cover image pixels for data hiding to achieve the desired QoS parameter. Performance comparison of the proposed scheme in terms of imperceptibility, capacity, PSNR, and RMSE w.r.t. the PVD-based steganography technique proves it to be an efficient technique.
