Abstract

Based on the combination of compressed sensing principle and DNA, a more effective and secure new method for image augmentation is proposed in this paper. After the original image is compressed by the measurement matrix, the DNA coding rule is used to perform the rule operation with the chaotic sequence generated by the Logistic chaotic system. This step is to perform pixel diffusion on the image, and use the Lorenz chaotic system to construct the index sequence to index the diffused image. Scrambling to obtain an encrypted image, and then decrypting it, using the principle of compressed sensing to process the decrypted image, and through the recovery algorithm (this paper uses the OMP reconstruction algorithm), the original image is successfully restored.
