This paper introduces a new (2, 8)-secret image sharing scheme integrating the chaos-based image encryption with secret image sharing. It divides the secret image into 8 encrypted shares. Combining any two or more shares is able to completely reconstruct the secret image without any distortion. Each image share is only one pixel larger than the secret image in row and column directions. The proposed scheme is able to directly process the secret images with various formats such as the binary, grayscale, and color images. Experimental and comparison results demonstrate the excellent performance of the proposed scheme.
