Another method is to have the server send out a generated hash code of some sort to the client (that expires after a set time); for the client to encrypt the score using the code and send it back.
Yet another mentioned on FlashCoders is to do the above, but send (along with score and name) game statistics - number of levels played, number of bullets fired, number of coins picked up or whatever and let the server do some basic sanity checking (there's no way he could have got 12000000 by picking up one coin!) Annoyingly, looks like the FlashGameCoders archives for the last few months are broken, so I can't point you at those... HTH, Ian On 9/12/06, Danny Kodicek <[EMAIL PROTECTED]> wrote:

Depends on your game to some extent. If they've found a bug in the game which enables them to get an artificially high score, there's nothing to do but fix the bug. But if they're doing it by just sending their own call to the server, bypassing your game altogether, then you can avoid this by adding some kind of encryption to the score. One method, for example, is to send the server three pieces of information: the score, the system clock time, and some number which combines the two in a secret way known only to you. (You could also encrypt the score itself, in order to make it even harder for the user to outguess you) Danny _______________________________________________ [email protected] To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
