Abstract
Recently, a polynomial-based (t,n) image sharing and hiding schemes with authentication was proposed to hid n shares of a secret image into n ordinary cover images and form n stego-images that can be transmitted securely. But each stego-image of all existing method should be expanded to 4 times of the secret image. In this paper we propose an enhanced scheme, where the size of the stego-image is reduced to times of the secret image. In addition our proposed scheme provides better authentication using hash function.
