Yahoo's Attempt at Anti-Phishing

Yahoo recently launched Sign-In Seal in an attempt to thwart phishing attacks. The concept is similar to the SiteKey used by Bank of America some time back. A Sign-In Seal is a secret message or an image selected by the user that Yahoo will display on the user's computer everytime the user visits Yahoo from the same machine. This can enable the users to make sure that they are on a genuine Yahoo site. The images below show how Yahoo SignIn seal can be used.
