Penrose tiling for visual secret sharing
Multimedia Tools and Applications, 2020Visual secret sharing (VSS) has the advantage that the decryption is based on our human visual system without participation of any computational devices. However, traditional VSS schemes are only for sharing raster images with regard to pixels, which lead to that the secret image will be aliased when enlarged and its pixels are shared in rectangular ...

Threshold visual secret sharing by random grids
Journal of Systems and Software, 2011A new visual secret sharing (VSS) approach by random grids (RG-based VSS), proposed by Kafri and Keren (1987), has drawn close attention recently. With almost all advantages of visual cryptography-based VSS, RG-based VSS benefits more from keeping the same size of secret images without the problem of pixel expansion from which VC-based VSS suffer.

Sharing visual multi-secrets using circle shares
Computer Standards & Interfaces, 2005Traditional visual cryptography technique has provided sufficient security to fulfill the purpose of protecting confidential messages. In current technology, the same set of shares can be embedded with many sets of secret messages after one of the shares is rotated at different degrees.

Block-based progressive visual secret sharing
Information Sciences, 2013Block-based progressive visual secret sharing (BPVSS) is an encryption technique that utilizes the human visual system to recover a secret image. The recovery method is based on building up different image blocks step by step. In the last few years, several research projects have been devoted to the study of BPVSS.

An Approach for Secret Sharing Using Randomised Visual Secret Sharing
2014 Fourth International Conference on Communication Systems and Network Technologies, 2014Visual secret sharing is the technique that divide the secret image into n multiple shares. Each share constitutes some information and when k shares out of n stack together the secret will reveal. However, less than k shares are not work. Sharing is the idea from secret sharing scheme that was presented in 1975 by Adi Shamir.

Multilevel Visual Secret Sharing
Second International Conference on Innovative Computing, Informatio and Control (ICICIC 2007), 2007This paper presents a novel visual secret sharing (VSS) scheme, called the multilevel VSS scheme, for sharing multiple visual secrets in an image among n participants. In the proposed n-level VSS scheme, the content of an image S is distributed to n levels of secrecy, and encoded to n+1 shares that exhibit the following features: (a) each share does ...
