An Secret Communication-oriented High Capacity Information Hiding Scheme Based on Cl Multi-wavelet and Combination Bit Plane

摘要

Take advantage of the first-order transformation of CL multi-wavelet, carrier image is decomposed into four components of lowest resolution sub-image. Use the feather of image bit plane embedded strategy. Propose an Information hiding scheme based on CL and Combination Bit Plane (CBP). LL2 is embedded module of robust parameters. Embed hiding Information in LH2 and HL2 with RAID4 and fragile sign in HH2. The position carried with embedded information of every sub-image is Bit Plane 0. Bit Plane 3 and Bit Plane 7 are auxiliary embedded positions by XOR. Before embedding, improve the consistence of the embedded data bits= order and the character of the sub-image with the chaotic map and the genetic algorithm. The embedding sequence of each bit plane is traversal according to Knight-tour route. Experimental results indicate that the proposed scheme can increase imperceptibility by 20.89% averagely and robustness by 17.20% and have excellent sensitivity of image processing .
