By reverse-engineering the modified amplitude-phase retrieval-based attack that has deciphered the phase-truncated double random phase encoding scheme, we proposed a new cryptosystem to encode a target image into a preselected fake image using a modified phase retrieval algorithm under the framework of phase-truncated double random phase encoding. With two private keys that are generated during the encryption, the decryption can be optically realized using a classical linear double random phase encoding method. The proposed cryptosystem has immunity against the recently proposed specific attack and the new attack based on a modified amplitude-phase retrieval algorithm. Numerical results are presented to demonstrate the validity and good performance of our proposed algorithm.
