In hierarchical secret sharing scheme (HSSS), the secret is shared among participants with different privileges that are distributed into distinct levels. Although HSSS has been proposed by several researchers, none of them have been used geometry characteristics to define conjunctive hierarchical secret image sharing (HSIS) scheme. Moreover, small shadow images have important role in transmission over the network and also in storage demand. The main objective of this paper is to propose conjunctive HSIS scheme based on generalized Blakley’s projective geometry scheme with small size of shadow images.
