Abstract Image sharing is an attractive research subject in computer image techniques and in the information security field. This article presents a novel scheme of image sharing with a $(\textit{t},$ $\textit{n})$ high-security threshold structure. The scheme can encode secret images into $\textit{n}$ shadow images in such a way that all the shadow images are in a $\textit{perfect}$ and $\textit{ideal}$ $(\textit{t},$ $\textit{n})$ threshold structure, while each shadow image has its own visual content assigned at random. The most common method to implement image sharing is based on interpolation polynomial over the field $F_{p}={0,$ 1, 2,…, $\textit{p}-1}$ [Shamir 1979]. In this article, the authors present a new approach to image sharing and its computation based on algebraic-geometry code over the pixel value field $GF(2^{m}).$
