Abstract:

<p>In the literature a lot of studies were carried out on (2,&nbsp;<em>n</em>) visual cryptographic scheme (<em>VCS</em>) using either XOR or OR operation. A scheme on ideal contrast (2,&nbsp;<em>n</em>)&nbsp;<em>VCS</em>&nbsp;with reversing using combined OR and NOT operations was reported. In this paper, a construction on an ideal contrast (2,&nbsp;<em>n</em>)&nbsp;<em>VCS</em>using combined XOR and OR operations with less amount of transparencies than ideal contrast (2,<em>n</em>)&nbsp;<em>VCS</em>&nbsp;with reversing using OR and NOT operations is proposed. This paper also shows a construction of (2,&nbsp;<em>n</em>)&nbsp;<em>VCS</em>&nbsp;with pixel expansion one which perfectly reconstruct the white pixels and probabilistically reconstruct the black pixel using XOR operation.</p>
