Abstract Multiple images steganography refers to hiding secret messages in
multiple natural images to minimize the leakage of secret messages during
transmission. Currently, the main multiple images steganography algorithms
mainly distribute the payloads as sparsely as possible in multiple cover images
to improve the detection error rate of stego images. In order to enable the
payloads to be accurately and efficiently distributed in each cover image, this
paper proposes a multiple images steganography for JPEG images based on
optimal payload redistribution. Firstly, the algorithm uses the principle of
dynamic programming to redistribute the payloads of the cover images to
reduce the… More >
