To create a secure authentication system, a physical unclonable function was introduced as an alternative to traditional technologies. PUFs utilize the randomness inherent in hardware to create unique digital fingerprints, which cannot be duplicated due to the unpredictability of the manufacturing process. Despite advancements, it still faces limitations, such as low encoding capability and difficulties in reconstruction. Here, we introduce a topological soliton maze in the chiral liquid crystal to overcome the hurdles. This platform functions as optical fingerprints and can be accurately verified by machine-learning object detection. The maze patterns are sufficiently randomized to make it difficult to predict and can be reconfigured through thermal phase transitions. Our security system, which is based on topological solitons that are microscopically controlled and macroscopically unpredictable, has the potential to provide a high-level security system.
