Abstract

This paper proposes a multisecret image sharing (MSIS) scheme for sharing multiple secrets in an image among n participants. In the proposed n-level MSIS scheme, the content of an image S is designated to multiple regions associate with n levels of secrets, and encoded to n + 1 shadow images which exhibit the following features: (a) each shadow image cannot get any region in S, (b) any t (2 < t < n + 1) shadow images can be used to reveal these regions with secret level equal to or smaller than t-1, (c) S can be reconstructed without any loss when all of the n + 1 shadow images are available.
