The main difference between visual cryptography (VC) and traditional cryptography is that when decrypting, only human vision is used instead of complicated calculations. With the reduction of hardware cost, XOR-based visual cryptography is the latest development of VC, which can solve the problem of low quality of recovered images in OR-based VC. In this paper, we will give three XOR-based VC schemes, which have meaningful sharing and can import n different cover images. Experimental results and analysis show that our schemes are better than currently known schemes.
