The multiple-image hiding system based on the Fresnel transform is proposed in the paper. In the hiding process, the multiple secret images are hidden by the phase only masks（POMs） which are generated with the chosen iterative algorithm,and the images can be reconvered in the different axes locations in the reasel domain with the corresponding position keys. The simulations results demonstrate the high quality of the revered multiple-image and the total multiplexing capacity of the system. The security of the system based on the phase keys and the additional keys is analyzed as well. |
