An optical double-image encryption and authentication method by sparse representation is proposed. The information from double-image encryption can be integrated into a sparse representation. Unlike the traditional double-image encryption technique, only sparse (partial) data from the encrypted data is adopted for the authentication process. Simulation results demonstrate that the correct authentication results are achieved even with partial information from the encrypted data. The randomly selected sparse encrypted information will be used as an effective key for a security system. Therefore, the proposed method is feasible, effective, and can provide an additional security layer for optical security systems. In addition, the method also achieved the general requirements of storage and transmission due to a high reduction of the encrypted information.
提出了一种基于稀疏表示的光学双图像加密与认证方法。来自双图像加密的信息可被整合到稀疏表示中。与传统的双图像加密技术不同，在认证过程中仅采用加密数据中的稀疏（部分）数据。仿真结果表明，即使使用加密数据中的部分信息也能获得正确的认证结果。随机选择的稀疏加密信息将被用作安全系统的有效密钥。因此，所提方法可行、有效，可为光学安全系统提供额外的安全层。此外，由于加密信息的高度压缩，该方法还满足了存储和传输的一般要求。
