| 中文摘要: |
| 目的 针对印刷量子点的点阵图像用于实现信息记录、信息隐藏和信息防伪时，存在因打印信息污损和图像识读信息误判引起的误码率高这一突出问题，设计一种信息可靠性编解码算法。方法 该算法采用二维奇偶校验码+BCH码+交织编码+帧同步组合方式。结果 经实验测试验证，该组合方式得到的印刷量子点图像与汉明码和RS编码相比，随机性更高，具有更加突出的纠错能力，信息解码识读速率更快、鲁棒性更好。结论 该算法可很好地解决印刷量子点信息的突发性错误和随机性错误，同时也解决了印刷量子点图像在信息防伪领域应用推广的瓶颈问题，扩展信息增值服务功能。 |

| In order to realize information recording, information hiding and information anti-counterfeiting, a kind of information reliability codec algorithm is designed to solve the prominent problem of high bit error rate caused by the stain of printed information and the misjudgment of image reading information when the dot matrix image of printed quantum dots is used to realize information recording, information hiding and information anti-counterfeiting. The algorithm adopts the combination mode of two-dimensional Parity Check code, BCH code, interleaved code and frame synchronization. The experimental results show that compared with Hamming code and RS code, the image of printed quantum dots obtained by the combined coding method has higher randomness, more prominent error correction ability, faster information decoding and reading speed and better robustness. This algorithm can well solve the sudden error and random error of printed quantum dot information, and also solve the bottleneck problem of the application and promotion of printed quantum dot image in the field of information anti-counterfeiting, and expand the value-added service function of information. |
