我们提出了一种光学安全的方法，使用光子计数加密实现与相位编码QR码的对象认证。将全相位双随机相位加密与光子计数成像方法相结合，应用迭代霍夫曼编码技术，实现了对包含目标主要信息的图像的加密和压缩。然后，该数据可以存储在光学相位编码的QR码内部，用于鲁棒的读出、解密和认证。通过使用统计分析检查光学掩模的散斑签名来验证光学编码的QR码。光学实验结果表明，该系统的性能。此外，实验与商业智能手机读取光学编码的QR码。据我们所知，这是第一份关于将光子计数安全与光学相位编码QR码相结合的报告。
We propose an optical security method for object authentication using photon-counting encryption implemented with phase encoded QR codes. By combining the full phase double-random-phase encryption with photon-counting imaging method and applying an iterative Huffman coding technique, we are able to encrypt and compress an image containing primary information about the object. This data can then be stored inside of an optically phase encoded QR code for robust read out, decryption, and authentication. The optically encoded QR code is verified by examining the speckle signature of the optical masks using statistical analysis. Optical experimental results are presented to demonstrate the performance of the system. In addition, experiments with a commercial Smartphone to read the optically encoded QR code are presented. To the best of our knowledge, this is the first report on integrating photon-counting security with optically phase encoded QR codes.
