Abstract

Internet is one of the most popular but insecure communication mediums. Since it is an open and insecure
medium, malicious users can intercept data when people transmit personal information. In order to achieve data
security, users need secure communication methods for transmitting secret messages over the Internet. Visual
Cryptography (VC) is a technique for achieving data security. It is simply a mechanical process in which the original
image can be decoded directly by the human visual system. In VC, one secret image is encoded into n shares that are
distributed to participants. Each participant cannot retrieve any information from his own transparency, but when at
least k of them superimpose their transparencies pixel by pixel, they retrieve the secret from the superimposed result
by using their visual system. In this paper, we propose a method that takes two secret images. These are fused together
and shares are generated out of this fused image. At the decoding side, shares are overlapped to get the fused image
back and then the original secret images are separated.
