Abstract A visually meaningful double-image encryption scheme using 2D compressive sensing and multi-rule DNA encoding is presented. First, scrambling, diffusing are performed on the two plain images, privacy images obtained, respectively. Then, re-encrypted theory to obtain secret images. Finally, integer wavelet transform (IWT) carrier image coefficients, then embedded into coefficients 2k correction performed, obtained result processed by inverse IWT a encrypted image. rules selected for pixel values of different positions in operations between key streams at controlled chaotic system. The application reduces amount data, thus increasing capacity introduction embedding process increases security simulation results demonstrate feasibility scheme, it has high data visual security.
