Dual Reversible Data Hiding in Encrypted Halftone Images Using Matrix Encoding

Data hiding and reversible data research has primarily focused on grayscale color images, because binary halftone images are prone to visual distortion caused by a small number of errors in pixel representation. As result, is more useful than halftone-based hiding. This study proposes an investigation encrypted based dual hiding, which improves the reversibility security image utilizing cover image. Since adequately compressed, they beneficial low-channel-bandwidth environments. Hamming code (HC) (7,4) applied each block hide secret data, two recorded sent different receivers at end embedding process. Recipients can use proposed method marked extract message recover The enhance quality decrypted appropriately increasing size, conversely, sufficiently large amounts be hidden reducing size. experimental results provide evidence effectiveness terms both rate.
