Abstract
An AAC steganography algorithm based on genetic algorithm and MDCT coefficient adjustment is proposed. Our algorithm selects the small value region of MDCT coefficient as the embedding bit and the coefficients in codebook 1/2 are designed to change. In order to be against steganalysis better, genetic algorithm is used to optimize the change of the coefficient. The experiment results show that the algorithm has good embedding capacity, high steganography and good imperceptibility.
