| The work aims to study and solve the problem of multi-image correlated imaging encryption. Double-QR coding was used to transform the multi-image correlated imaging encryption problem into the problem of a single QR code correlated imaging encryption. As imaging objects of correlated imaging, QR code could reconstruct clear images under the condition of being far lower than the sampling rate of traditional correlated imaging, and achieve the high quality information recovery. Under the condition of ensuring the image quality, the algorithm has higher security, can effectively resist the attacks of certain noise and statistical analysis, and greatly reduces the encryption cost of the encryption system for multiple images. |
