Exploring high-safety but convenient encryption and decryption technologies to combat threats of information leakage is urgently needed but remains a great challenge. Here, a synergistically time- and temperature-resolved information coding/decoding solution based on functional photonic inks is demonstrated. Encrypted messages can be stored into multiple channels with dynamic-color patterns, and information decryption is only enabled at appointed temperature and time points. Notably, the ink can be easily processed into quick-response codes and multipixel plates. With high transparency and responsive color variations controlled by ink compositions and ambient temperatures, advanced 3D stacking multichannel coding and Morse coding techniques can be applied for multi-information storage, complex anticounterfeiting, and information interference. This study paves an avenue for the design and development of dynamic photonic inks and complex encryption technologies for high-end anticounterfeiting applications.
探索高安全性但方便的加密和解密技术以应对信息泄露的威胁是迫切需要的，但仍然是一个巨大的挑战。在这里，展示了一种基于功能光子油墨的协同时间和温度分辨信息编码/解码解决方案。加密消息可以存储到多个具有动态颜色模式的通道中，并且只有在指定的温度和时间点才能进行信息解密。值得注意的是，这种油墨可以很容易地加工成快速响应码和多像素板。由于油墨成分和环境温度可以控制高透明度和响应颜色变化，因此可以应用先进的 3D 堆叠多通道编码和莫尔斯编码技术来进行多信息存储、复杂防伪和信息干扰。这项研究为动态光子油墨和复杂加密技术的设计和开发开辟了道路，可用于高端防伪应用。
