| Abstract | ||
| In this work, a novel optical triple-image encryption and authentication method based on joint transform correlator and a classical 4f-correlator is proposed. By using this method, three images can be encrypted together into one image at the same time. The encrypted image achieved the requirements of simultaneous recognition, invisible content and high secure authentication. Simulation results were presented to verify the validity of the proposed method. Nonlinear operation is also presented to enhance the authentication process of the encrypted data. In addition, the performance of the system demonstrates that the proposed method is feasible and effective to encrypt three images. http://dx.doi.org/10.31257/2018/JKP/100108 | ||
