Abstract: The present disclosure generally relates to information security and, more particularly, to systems and methods implementing color image ray transform (IRT) for detecting phishing web pages. A focus is comparing the features of a questionable website to features of a legitimate website. Detection of a phishing website using color IRT includes: requesting access, on at least one computing device, to a web page having a Universal Resource Locator (URL); comparing, using the at least one computing device, the URL of the requested web page to a reference URL within a database stored in a memory; determining, using the at least one computing device, that the URL of the requested web page matches the reference URL; and generating, using the at least one computing device, a message that the web page is legitimate when there is a match between the URL of the requested web page and the reference URL.
