An Intragroup and Intergroup Multiple Secret Images’ Sharing Scheme with Each Participant Holding One Shadow Image

Abstract: In some particular situations, participants need to recover different secrets both within a group (i.e., intragroup) and between two groups (i.e., intergroup). However, most of the existing multilevel secret sharing (MLSS) and multigroup secret sharing (MGSS) schemes mainly focus on how to protect a secret between one or more groups. In this paper, we propose a polynomial-based scheme to share multiple secret images both within a group and between groups. The random elements’ utilization model of integer linea… Show more

“…In 2020, Chen et al [20] studied boolean-operation for MSIS and introduced a general access structure, but the general structures of other MSIS principles do not be proposed yet. Wang et al [21] proposed a polynomial-based scheme to share multiple secret images both within a group and between groups for access control, but the applications of the scheme was too limited. Liu et al [22] introduced a (k 1 , k 2 , n)-threshold two-in-one secret image sharing scheme with PSIS and random gridbased visual cryptography scheme (RGVCS) for multiple secrets, but the payload was not ideal.…”
