User behaviour based phishing websites detection

Xun Dong, John A. Clark, Jeremy L. Jacob
2008 International Multiconference on Computer Science and Information Technology  
Phishing detection systems are principally based on the analysis of data moving from phishers to victims.  ...  In this paper we describe a novel approach to detect phishing websites based on analysis of users' online behaviours -i.e., the websites users have visited, and the data users have submitted to those websites  ...  UBPD is not designed to replace existing techniques. Rather it should be used to complement other techniques, to provide better overall protection.  ...

Clustering-based incremental web crawling

Qingzhao Tan, Prasenjit Mitra
2010 ACM Transactions on Information Systems  
We design a crawling algorithm that clusters webpages based on features that correlate to their change frequencies obtained by examining past history.  ...  The crawler downloads a sample of webpages from each cluster and depending upon whether a significant number of these webpages have changed in the last crawl cycle, it decides to recrawl the entire cluster  ...  We adopt the technique here for the incremental crawlers to detect webpages' updates that may affect the performance of search engines.  ...
