Detecting Dynamic Cloaking on the Web

Web spam refers to some techniques, which try to manipulate search engine ranking algorithms in order to raise web page position in search engine results. In the best case, spammers encourage viewers to visit their sites, and provide undeserved advertisement gains to the page owner. In the worst case, they use malicious contents in their pages and try to install malware on the victim’s machine. Spammers use three kinds of spamming techniques to get higher score in ranking. These techniques are Link based techniques, Hiding techniques and Content-based techniques. There are two available methods in hiding techniques; cloaking and redirection. Cloaking has also two categories; static cloaking and dynamic cloaking. Previous cloaking detection methods are based on static cloaking. Our method is detecting dynamic cloaking, which is a new and complicated kind of cloaking. Experimental results show that the accuracy of our algorithm is high and it can find cloaking pages more effectively than previous methods.
