Stop flash running from player ( outside browser) and accessing a web page

Question

Let's say i have a 2-player (multiplayer) game. What if a user ( a hecker ) saves the swf, decompiles it, cheats into the code ( makes the game easy and winnable) , and runs the game from flash player ( As after decompiling and modifications, naturally it cannot be run from game-owner's server)

How can i restrict him playing the game via flash player (outside the browser) ?

What i think is, i must use PHP session on the page, where the flash game is being loaded. Can that do the trick ? Any suggestions ?

Thanks

You can't protect SWF files completely, but one thing you could do is check if url contains "localhost" or NOT the web url for the game. It is called site-locking.
