In order to construct a Perfect and Ideal image threshold secret sharing scheme (Complete Scheme) and improve sharing efficiency, a novel secret image sharing complete scheme based on array codes with a (t, n) threshold structure was proposed. The scheme takes image pixel values, in binary form, as the data in disk array, encodes image pixel array using the method of array code. The operation of the scheme is XOR only, and the process is in a parallel way, while the threshold structure is Perfect and Ideal. The results show the proposed scheme is more efficient and has higher security.
