Abstract
Dividing an image in several components and sharing through different channel is popular way of sharing and storing sensitive image data. We proposes here a simple image secret sharing method based on random matrices. These random matrices act as key for secret sharing. The technique allows a secret image to be divided into three image shares where each share individually looks meaningless. To reconstruct the secret image all three shares have to be used. This method has no pixel expansion and can reconstruct the secret image precisely. This scheme can be directly applied on gray scale images and can easily be extended to binary and color images. Experimental results prove that this scheme can generate good quality of reconstructed images.
