Abstract
En 中文
The existing encryption schemes of visually secure image have drawbacks, such as excessive concentration of image data and insufficient resistance to various attacks in the transmission channel. Based on the combination of compressed sensing and secret image sharing, this paper presents a visually secure multi-secret image encryption-sharing scheme, which effectively solves the above shortcomings. First, the plain image is perceived as sparse and encrypted by semi-tensor compressed sensing for security. Secondly, the encrypted image is divided into n shadows by secret image sharing. This solves the problem of image data being too centralized and meets the requirements of risk dispersion and intrusion tolerance. Finally, the n shadows are embedded into n carriers by steganography technology to form a visually secure image. On the basis of guaranteeing the quality of image reconstruction, this paper has high compression and security.
