With the rapid growth of multimedia message exchange and digital communication, big data has become a research hotspot in various fields. The storage transmission have high requirements for security. Images, covering highest proportion data, should be processed transmitted with Compressive sensing (CS) beneficial property encryption that image can recovered fewer samples than conventional approaches use. In recent years, CS been studied not only to reduce resource signal acquisition but also ensure security data. It is still an open challenge improve enhance quality decrypted simultaneously using key small size. this article, CS-based method presented associates quantization random measurement permutation. An enormous number experiments conducted on both standard test images face chosen from database LFW. Experimental results show our proposal dramatic improvements ensuring security, enhancing image, raising efficiency. Additionally, remarkably reduces resources. Accordingly, scheme applied transmission.
