An institute in a European country (Croatia) has developed a clever way to keep hackers from entering their website by requesting a person enter their name, password, affiliated organization, and above all, solve a calculus math problem. I personally think this is somewhat effective for increased security, but it would be a problem for members of the institute who are knowledgeable about math. Besides, there are websites that could solve math problems so hackers could still be able to enter websites.

This sounds like a very efficient way to increase Web Security. The fact that they need to do a calculus math problem doesn't make much sense to me though. They should make the question something that is a commen thing for everyone to know maybe a reading comprehension question.
