I'm wondering if it is possible to find out if someone is graduated from a University. Like, I could write on my CV that I graduated from Harvard, but then how can you prove it? Suppose I'm an excellent hacker, I could still fool people by doing clever tricks that make a counterfeit of a diploma or something. So I'm wondering if there is an official protected and verified database that records the information that a person is a graduate from a specific university?
Suppose that I'm an employer and I want to verify my candidate is a graduate of X university, how do I do that? What if the university is in Canada?
