检索信息如下 Optimal pixel expansion of deterministic visual cryptography scheme 作者:Fu, ZX (Fu, Zhengxin)[ 1 ] ; Yu, B (Yu, Bin)[ 1 ] MULTIMEDIA TOOLS AND APPLICATIONS 卷: 73 期: 3 页: 1177-1193 DOI: 10.1007/s11042-013-1625-3 出版年: DEC 2014 查看期刊信息 摘要 The optimal pixel expansion is an important parameter of deterministic visual cryptography scheme (DVCS). There are many researches have been done under different access structures and stacking operations. However, any necessary or sufficient condition has not been found about the optimal pixel expansion. In this paper, we give a necessary condition of the optimal pixel expansion of DVCS for the first time, which is suitable for any access structure and any stacking operation. Furthermore, a pixel expansion optimization algorithm has been designed to improve the existing schemes. It is found that the pixel expansion can be reduced for most DVCS based on XOR operation. Finally, we give some experimental results and comparisons to show the effectiveness of the proposed scheme. 关键词 作者关键词:Visual cryptography; Deterministic; Necessary condition; Pixel expansion KeyWords Plus:SECRET SHARING SCHEMES; CONSTRUCTION 作者信息 通讯作者地址: Fu, ZX (通讯作者) Zhengzhou Informat Sci & Technol Inst, Dept Comp Sci & Informat Engn, Zhengzhou, Peoples R China. 地址: [ 1 ] Zhengzhou Informat Sci & Technol Inst, Dept Comp Sci & Informat Engn, Zhengzhou, Peoples R China 电子邮件地址:fzx2515@163.com; byu2009@163.com 基金资助致谢 基金资助机构 授权号 National Natural Science Foundation of China 61070086 查看基金资助信息 出版商 SPRINGER, VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS 类别 / 分类 研究方向:Computer Science; Engineering Web of Science 类别:Computer Science, Information Systems; Computer Science, Software Engineering; Computer Science, Theory & Methods; Engineering, Electrical & Electronic 文献信息 文献类型:Article 语种:English 入藏号: WOS:000344744200006 ISSN: 1380-7501 eISSN: 1573-7721 期刊信息 Impact Factor (影响因子): Journal Citation Reports® 其他信息 IDS 号: AT2EH Web of Science 核心合集中的 "引用的参考文献": 26 Web of Science 核心合集中的 "被引频次": 0 |
