In order to solve the crosstalk problem between decrypted images, quick response (QR) code is introduced in the image encryption system based on principle of interference. The encryption process is realized on computer digitally and the decryption process can be completed optically or digitally. For encryption, multiple sets of the information to be encrypted is first transformed into the corresponding QR code, then these QR codes are analytically hidden into two phase only masks (POMs). For decryption, the diffraction field of the two POMs is superposed by utilizing the beam splitters. After that the wavefront propagates to different distances and the intensity of the complex field, which are exactly the decrypted images. Directly scanning by a smartphone, original information can be completely retrieved. The encryption method successfully solves the problem of crosstalk noise. Simulation results are presented to verify the validity of the proposed approach. The feasibility and robustness against occlusion and noise attacks are verified by a series of numerical simulations.
