A Novel Multi Secret Sharing Scheme Based on Bitplane Flips and Boolean Operations

Abstract

Visual secret sharing is a process of distributing the information into multiple encrypted shares, overlapping those shares according to access structure reveals the secret. In the last two decades several schemes have been proposed for single secret as well multi secret sharing. The present paper proposes a multi-secret sharing scheme based on bitplane flipping and Boolean operations. Image retrieval is lossless and the scheme uses two levels of encryption which makes it more secure. Robustness of the method is demonstrated using numerical results.
