Abstract. We present a novel hybrid method that includes a modulated scheme for reducing the distortion of the reconstructed image and a two-layered structure for grouping particip...
This paper solves the visual cryptography problem by the Blakley scheme that is a geometry-based secret sharing strategy. We first partition the protected image into non-overlappi...
In this paper, we present a new method for sharing images between two parties exploiting homomorphic property of public key cryptosystem. With our method, we show that it is possib...
The visual secret sharing (VSS for short) scheme is a secret image sharing scheme. A secret image is visually revealed from overlapping shadow images without additional computation...
This paper considers the problem of encoding a secret binary image SI into n shares of meaningful halftone images within the scheme of visual cryptography (VC). Secret pixels enco...
