Double Image Encryption Scheme Based on Compressive Sensing and Double Random Phase Encoding

In order to overcome the shortcomings of standard compressive sensing (CS) encryption framework, a novel fusion application scheme CS and optical transformation technology is proposed. The proposed scheme, making full use feature achieve compression simultaneously, compresses encrypts two images into one image, which not only reduces storage space transmission bandwidth, but also improves security performance encryption. original are first sampled with CS, then double random phase coding performed obtain small-sized images. Meanwhile, directly encrypted authentication information. Next, we combine information finally perform again final image. It should be emphasized that has function image authentication. Experiment results validate effectiveness advancement scheme.
