Two-Dimensional Barcode Encryption Technology Based on Improved Chaotic Sequences of Logistics
Jian Zhou, Li Cai · Applied Mechanics and Materials · 2013
A new method for two-dimensional barcode encryption through using improved chaotic sequences of logistics has been proposed. The image of two-dimensional barcode was divided into two parts and chaotic sequence for encryption with the two parts was used respectively. Experiments results denoted that five key ensured the encrypted image higher security. The MSE between the original image and the encrypted image is 3.49×106. Computer simulations are presented to verify its good resistance to salt and pepper noise.
