提出了一种基于干涉图像隐藏系统和纯相位相关的光学认证技术。该方法根据干涉原理，将预定义的幅值不同、相位相同的复图像分别编码成两个纯相位掩模。该技术可以方便地为不同的用户生成不同的验证密钥，为多用户应用带来了方便。在验证阶段，同时产生尖锐的相关峰和代表用户身份的重要图像。因此，除了简单的验证外，该方法还可以识别用户的身份。此外，该技术还可以有效地防止验证密钥被他人伪造。数值仿真结果验证了该方法的有效性和可行性。
An optical authentication technique based on interference image hiding system and phase-only correlation is proposed. In this method, some predefined complex images with different amplitudes and the same phase are respectively encoded into two phase-only masks according to the interference principle. This technique can easily generate different verification keys for different users, so it brings convenience for multi-user application. In the verification stage, both a sharp correlation peak and a significant image represented the identity of a user are generated simultaneously. Therefore, in addition to simple verification, this method can also recognize the identity of the user. Moreover, this technique can effectively avoid the verification key being forged by other person. All the performances and the feasibility of our proposed method are tested by numerical simulations.
