Reversible Data Hiding Based Bit-Plan Permutation and Absolute Moment Block Truncation Coding (AMBTC)

Data hiding is one of the branches of information security, and it is used in the field of communications and computer networks which be a solution when a secure channel is not available. In this paper, an information hiding method into codded images. A bit plan applied on the secret image and reshaped into the vector, while an Absolute Moment Block Truncation Coding (AMBTC) is used for coding color images (cover images). The coding is applied as a method for size reduction by representing each block with two means called Mb, Ma, and Bit-map that represent the location of them in binary form. The embedding of secret information is represented by modifying the bit-map. Additional complexity is added to the method by permutation the bit plane vector using a chaotic map called the logistic map. The proposed method was examined and proved its efficiency by obtaining a high PSNR and a low RMSE result, as well as the visual testing through the histogram test of the image before and after embedding.
