The XOR-based visual cryptography (VC) is a possible methodology to solve the poor visual quality problem without darkening the background in VC. However, investigations on XOR-based VC are not sufficient. In this paper, we exploit some extended capabilities for XOR-based VC. Actually, two XOR-based VC algorithms are proposed, namely XOR-based VC for general access structure (GAS) and adaptive region...
In this paper, a novel visual data hiding method is proposed to conceal a binary visual pattern into a dot diffused halftone image. The visual pattern is revealed by copying the halftone image, shifting the copy and superimposing the shifted copy and original halftone image together. The self-decrypt property of the proposed method make it more robust against geometry distortion, while other existing...
