How to check unique person


hackerkts

Recommended Posts

As the subject says, how do you guys actually check if the person is unique.
What I mean is, hmm... Let's take this example:

I have a voting system, but I wanna make it only 1 person to vote once.
But I can't set it as 1 person vote one time according to their IP address, some of the people have dynamic IP (which changes everytime they restart their cable/modem)

Is there a way to check MAC address and use it in PHP code ?

Sorry, I'm dumb with computer. :s

And there is the opposite problem, as in a classroom situation, where several users may have the same IP
