BEMSS- Blockwise Encryption based Multi Secret Sharing scheme for Securing Visual Content

In recent years, the significant research area in the domain of multimedia security is image information security. This can be provided by converting it into a secret code through the process of encryption or hiding its true significance or a combination of both. It is required in many domains like defence, military, banking, education, etc, to keep these sensitive images from being hacked or destroyed. In this paper, BEMSS, an (n,n) multi-secret image encryption with a secret sharing scheme is proposed using blockwise encryption. In the proposed technique two-level encryption, modulo and inter blockwise encryption, are performed to the n secret images, and a two-level share generation process is performed to the encrypted images. BEMSS recovers n lossless the secret images by modulo and blockwise decryption process. Experimental results obtained show the effectiveness of the proposed BEMSS which provide a computationally efficient security scheme.
