Abstract
In this paper, we propose a novel and simple (2, n) secret sharing scheme with precise reconstruction for grayscale, binary and color image. The share construction phase is based on pixel division and XOR operation. The reconstruction is based on XOR and OR operation. The proposed scheme has no pixel expansion and can reconstruct the secret image precisely. This scheme can be directly applied to share grayscale images and can be easily extended to deal with binary and color images. Experimental results prove that the proposed scheme is efficient because of strong security and accuracy.
