Windows IT Pro Security Update - Phishing and Pharming - June 22

covered Green Armor Solutions' new Identity Cues offering. To quote:

Another new solution, Identity Cues from Green Armor Solutions, works at the Web site level. The first time a user logs on to an Identity Cues-protected Web site, the product generates colored visual cues that will then appear each time the user logs on to the site. A spoofed Web site won't be able to generate the same cues, so a user sent to a spoofed site will immediately know that he or she isn't visiting the legitimate Web site. Identity Cues is definitely a novel concept.
