A New Dual Image Based Reversible Data Hiding Method Using Most Significant Bits and Center Shifting Technique

In this article, a new reversible data hiding method using most significant bits and center shifting technique in dual images is proposed. The proposed aims to securely hide high-capacity secret data. Instead of directly embedding the data, calculates values with (n + 1) n cover image pixel values. Thus, it impossible extract without obtaining original image. Also, process performed minimize mean square error. After process, be hidden are range [−3×2(n−1)+1, 3×2(n−1)−1]. stego obtained by value As result experimental studies, when payload 2.5 per (bpp), peak signal-to-noise ratio (PSNR), which expresses visual quality, above 34 (dB). addition, has proven secure against RS (regular singular) analysis attacks.
