An approach to phishing webpage strategy based on optical semblance assessment is proposed, which can be utilized as a part of an enterprise solution to anti-phishing. The approach first decomposes the webpages into salient (visually distinguishable) block regions. The optical semblance between two webpages is then evaluated in three metrics: block level similarity, layout similarity, and overall style similarity. A webpage is reported as a phishing suspect if any of them (with regards to the true one) is higher than its corresponding preset threshold.
