Suppose Yahoo! places Yahoo! badge on every website on request, and if a customer of that site sees the Yahoo! badge on that site and clicks on it, is it possible for Yahoo! to identify if he has logged into Yahoo! from that site? If it is possible, then Yahoo! can think of giving sign up and sign in incentives for the website that has posted the Yahoo! badge. Your answers will be appreciated. Thanks in advance.
