Analysis of Feature Enhancements in Visual Secret Sharing

Visual Secret Sharing (VSS) aims at sharing of secrecy among many shadows depending on the number of dealers. These encrypted shadows themselves cannot reveal secrecy. A group of a pre-qualified number of shadows is sufficient to obtain the secret image. The quality of this secret is usually approximate to the original confidential image. This technique has evolved, offering solutions to the demands of the matured Internet domain. This paper analyzes the feature advancements in the VSS field. The VSS approaches remain distinct from the conventional cryptography, thereby offering new security solutions in many applications. Security being the central and challenging demand in contemporary information systems, the analysis of the state-of-the-art VSS stands significant.
