We propose a novel method for multiple-image encryption using a phase retrieve algorithm and intermodulation in the Fourier domain. All plaintexts to be encoded are first encoded separately into a phase-only function in the Fourier domain with the help of the phase retrieve algorithm. Then these phase-only functions serve mutually as the second encryption keys to be intermodulated into a single image. As a result, all plaintexts can be extracted from the ciphertext without any cross-talk and the encrypted capacity is nearly unlimited. The feasibility and effectiveness of the proposed method are demonstrated by numerical results.
