Information hiding (IH) Algorithm Based on Gaussian Pyramid and GHM (Geronimo Hardin Massopust) Multi-wavelet Transformation

Proposed an Information Hiding Algorithm based on Gaussian pyramid and GHM multi-wavelet transform. Applied Gaussian pyramid and GHM multi-wavelet transform to generate the different energy embedding regions. Embedded the robust parameters in the hightest energy region of images, the main hiding information in higher energy region with RAID4 and fragile sign in lowest energy region. We improved the consistency of the embedded data and the cover image by scrambling the cover image with Chebyshev map and changing scrambling parameters. The position for embedding information of every region is Bit Plane 0 of B color component. Bit Plane 3 and Bit Plane 7 are auxiliary embedded positions by XOR. Experimental results indicate that the proposed algorithm can increase invisibility and is of better robustness against JPEG2000 compression, cutting, rotation, filtering and noise, and has certain ability against steganalysis such as the RS and high order statistics based on wavelet coefficients. Moreover, the algorithm has excellent sensitivity to image processing.
