Weifeng Zhang, Hua Lu, Baowen Xu, Hongji Yang
2013 Informatica (Ljubljana, Tiskana izd.)  
In particular, we develop two different options to extract the spatial layout features as rectangle blocks from a given web page.  ...  One of the keys of phishing detection is to efficiently search the legitimate web page library and to find those page that are the most similar to a suspicious phishing page.  ...  In particular, analyzing search logs discloses the search terms commonly used by attackers, which indicate vulnerable web sites. There also exists similarity based anti-phishing.  ...
