Abstract :
In this paper, we propose a novel (n, n) secret image sharing scheme. The construction of shares is based on matrix multiplication and the revealing is based on addition. The proposed scheme has no pixel expansion and can reconstruct the secret image precisely. It can be directly used to share grayscale images and can be easily extended to deal with the binary and color images. Experimental results show that the proposed scheme is efficient.
