Designing a Software that Detect and Block Phishing Attacks

Abstract Phishing is a significant security threat to the Internet , which causes tremendous economic lost every year. Phishing is a way of attempting to acquire sensitive information such as username, password, and credit card details by masquerading as a trustworthy entity in an electronic communication.This is similar to Fishing, where fisherman puts a bait at the hook, thus, pretending to be a genuine food for a fish. This paper present a new end-host based anti-phishing algorithm, TF-IDF, by utilizing the characteristics of the KEYWORD RETRIEVAL and LOGO-detection technique.Our experiments verified that TF-IDF and LOGO detection is effective to detect and prevent both known and unknown phishing attacks.
