Abstract: Visual Cryptography is a special encryption technique to hide information in images in such a way that it can be decrypted by the human vision if the correct key image is used. Visual Cryptography uses two transparent images. One image contains random pixels and the other image contains the secret information. It is impossible to retrieve the secret information from one of the images. Both transparent images and layers are required to reveal the information. In this paper (2,n) BVCS and an encryption algorithm are proposed to hide the text, audio and image that should be fed as a digital image in the system as the input and the system generates “n” (2≤n) numbers of different images called shares, look like images of random noise. Among “n” number of shares user has to stack “k” number of shares, where 2≤k≤n, to reveal the secret. In order to reduce the transmission risk of the shares, SIRDSs are used as cover images of the shares of VCSs. The audio recorded is converted to text and is encrypted using an image. It is then send to the receiver, who decrypts the encrypted data and the audio and text is revealed.
Keywords: Shares, BVCS, Visual cryptography.
