A novel multi secret image sharing scheme for different dimension secrets

The existing state of the art schemes deals with the same dimension secret images but less work is available in the literature for different dimension secret images. In this paper, we have proposed an efficient multi secret image sharing scheme for different dimension secret images. In the proposed scheme, Chinese Remainder Theorem (CRT), shift and XOR operations are used for shares generation and secrets reconstruction to provide more randomized shares without revealing any secret information. The proposed scheme is attack resistive as if there is an attack on any of the share(s) then the reconstructed secrets doesn’t reveal the attacked portion whereas the remaining portion of the secrets gets reconstructed correctly. This confirms that an attack has been performed on the share(s) during transmission. The quantitative analysis of the proposed scheme is performed using Jaccard coefficient, correlation, RMSE, PSNR, MAE, NPCR, UACI, Information Entropy, and EQ parameters whereas the qualitative analysis has been performed using histogram analysis. The experimental results shows that the proposed scheme performs better on different dimension secret images.
