EXPERIMENTAL ANALYSIS
Approach Accuracy Time (second)
IP based URL 100% 17
Exists in phishing
database
97% 59
Matching source content 81% 134
Abnormal condition 79% 51

DISCUSSION Our approach reduces the ability of attackers
to automate their attacks, cutting into their profitability.
By using the minimal knowledge base provided by the user-selected web-page, our system is able to compare potential phishing sites with real sites.
Performance and accuracy can be improved by using an image segmentation algorithm.
Flash contents can’t be validated whether phishing threat or not in our system.
