TLDR
In this paper, another construction of (k, n)-PVCS was proposed by extending the (n, k)-DVCS and the probabilistic VCS.Abstract:
Visual cryptography scheme (VCS) is a secure method that encrypts a secret image by subdividing it into shadow images Due to the nature of encryption VCS is categorized into two types: the deterministic VCS (DVCS) and the probabilistic VCS (PVCS) For the DVCS, we use m (known as the pixel expansion) subpixels to represent a secret pixel The PVCS uses only one subpixel to represent a secret pixel, while the quality of reconstructed image is degraded A well-known construction of (k, n)-PVCS is obtained from the (k, n)-DVCS In this paper, we show another construction of (k, n)-PVCS by extending the (k, k)-PVCSread more

AnimVSS: Frame-Based Visual Secret Sharing
TL;DR: This paper proposes a methodology to use random grid shadow images to encode series of frames comprising short animations, useful in situations when a mere static image is insufficient to convey a secret instruction.
