Paper Abstract

In the paper a single channel color image encryption method based on compressed sensing (CS) was proposed. Firstly, a color image was modulated to the gray images by using a tricolor grating, and then the spectrum of the gray images was encrypted by applying CS technology, and regards the measurement matrix as a key. Decryption by choosing suitable filtering window, extract the R, G, B gray image spectrum reconstruction, finally achieved the reconstruction of the original color image. The simulation results indicate that this encryption method can effectively reduce the amount of sampling data, reduce the burden of subsequent storage, transmission and processing information. At the same time, it can increase the key space, and effectively improve the security of encryption.
