Improving the Visual Quality of (2, n) Random Grid Based Visual Secret Sharing Schemes

Conference paper
Part of the Smart Innovation, Systems and Technologies book series (SIST, volume 44)

Abstract

Visual secret sharing scheme (VSS) based on the concept of random grid (RG) that suffers from low visual quality of the decrypted secret. In this work a (2, n) RG based VSS has been proposed to improve the contrast. The proposed scheme supports the traditional stacking decryption method. To improve the visual quality further a decryption algorithm is proposed. The experimental result and comparison of visual quality with related methods has shown that the proposed schemes perform well.
