An unclonable, fingerprint-mimicking anti-counterfeiting strategy is presented that encrypts polymeric particles with randomly generated silica film wrinkles. The generated wrinkle codes are as highly unique as human fingerprints and are technically irreproducible. Superior to previous physical unclonable functions, codes are tunable on demand and generable on various geometries. Reliable authentication of real-world products that have these microfingerprints is demonstrated using optical decoding methods.
提出了一种不可克隆、模仿指纹的防伪策略，该策略使用随机生成的二氧化硅薄膜褶皱对聚合物颗粒进行加密。生成的褶皱代码与人类指纹一样具有高度独特性，在技术上是无法复制的。与以前的物理不可克隆函数相比，代码可以按需调整，并且可以在各种几何形状上生成。使用光学解码方法可靠地验证了具有这些微指纹的实际产品的真实性。
