I’d like to have a score table for a Flash game and keep it in a database (using **loadVars ** method).
The problem is: how to prevent the score faking?
In normal situation, when the game is over - the score table is called from within Flash and a new score is written in it.
But, there are people who will want to make e.g. one million points without playing a game! 
They will decompile a .swf, see what loadVars does, and write a score from their custom .php form.
How to prevent it?
Normal authentication isn’t suitable here, because the game is open to everybody.
