Information encryption and decryption processes to convert between ternary and binary 3D-code arrays (IMAGE)
Caption
In the top of the figure can be seen different fluoresces are given different information (No emissive = 0, Red = 1, Green = 2), composed of different polymer blocks of 3D Code A upon different UV light and visible light exposure, such as the decryption method reported in the article, the system state gradually decrypted information "HNUST" (a, b, and c), due to the strong self-healing ability, 3D Code A can be quickly reconstructed to 3D Code B, similarly, it can also decrypt for new information "HUNAN" (d, e, and f). “The self-healable pixel units allowed for rapidly rearranging and assembling new encrypted information” Chen says.
