A secret image kept in a single information-carrier could be easily retrieved or damaged by unauthorized entity.In the gigantic internet communication, the secret image sharing schemes can be used to share a secret image with utmost confidentiality over unsecured public channels.In this scheme a secret image is programmed into n transparencies of arbitrary prototypes.It is possible to decode the secret image visually by superimposing a qualified subset of transparencies.Nevertheless, no secret image can be acquired from the superposition of an illegal subset.In this paper, an efficient Ant Colony Optimization (ACO) algorithm is proposed for secret image sharing scheme.The original secret image pixels and key matrix is used to construct the transparencies.Here an ACO algorithm is utilized to optimize the key matrix to improve the transparency image quality.Experiments are conducted to show the security and efficiency of the proposed scheme.Comparisons with previous approaches show the advantages of the proposed scheme.
