A secure Web-based watermarking scheme is proposed to allow the publisher or information provider to mark their copyrighted materials and identify an illegal distributor through the World Wide Web (WWW). In our proposed scheme, multi-watermark techniques and double encryption method is applied to make the scheme available in e-transaction and secure against collusion attacks even if the third party...
The present paper is an introductory summary of an alternative roughness theory to classic rough set theory (RST), the granular rough theory (GrRT). GrRT differs from classic RST mainly in the underlying representation model, the granular representation calculus, which is designed to accommodate semi-structured information sources, to explicitly encode semantic contexts inherent in information sources...
Building rules on top of ontology is the main task of mining the logical layer of the semantic Web. In order to find the user-access patterns in the Web usage records, an ILP approach to mine the log ontology based on AL-log is illustrated in this paper. At first this paper gives the definition of event and log ontology, and then discusses the semantics of AL-log. Compared with traditional Web log...
In order to improve some fundamental problems of the clonal selection algorithm (CSA), a novel clonal selection algorithm (NCSA) is proposed. After analyzing the mechanism of the clonal selection and proposing the antibody model, the basic character of the application problem fused into the NCSA based on rearrangements of antibody molecule coding genes. Next, we analyzed synthetically the antibody-antigen...
