After some ideas to solve the following.
A game based around php/mysql.
Users create an account that allows them to play the game, however creating multiple accounts gives them an unfair advantage over other players (one account can be used as a 'bank' for the other etc)
So what i need is a reliable way of restricting accounts to one per computer.
I have tried using cookies, but the more astute users modify or delete the cookies between creating accounts so that was only partially successful.
I have tried requiring email validation, the account must be validated with a code sent to an email address, hotmail.com etc makes it fairly easy for people to create multiple email address so again only partially successful.
What im after is some sort of unique identifier for a particular computer / user that i can store in the user table, i can then compare new accounts to this existing value and if i get a match reply with something like...
"Our records show an account allready registered to this computer, game rules allow only 1 account per player, please delete your existing account to continiue"
So are their any such unique identifiers ? any ideas at all greatly appreciated.
