Abstract: This paper proposes a novel phase-shifting digital in-line holography with computer-generated holograms (CGHs) to achieve the goal of encryption via multiple-key encoding. Multiple keys will also be required in order to complete the decryption. These keys include the amplitude and the phase distribution of the primary encryption key, the reconstruction distance of the image, and the phase value modulated via micro phase-shifting interferometry. Experiments in this research have proved that the decryption would not be possible without a primary key. The autocorrelation between the original and the decrypted images shows very high similarity.
