Popis:	In the traditional secret sharing schemes, all participants are equal in terms of privileges but in special situations participants may not be equal. In this article we consider generalized compartment access structure and linear secret sharing schemes for their realization. Nested compartment access structure is considered where a hierarchical levels are defined within compartment. Also a perfect ideal secret sharing scheme for nested compartment accesses structure is proposed. Proposed schemes are ideal and perfect. Nested compartment image secret sharing schemes is considered and perfectness of the schemes is proven. In proposed scheme size of shared images is equal to secret image and PSNR in these schemes is infinite.
