[Flash] - Preventing Hacking Attempts

[kratsg]

I've got a couple of Flash games which posts data to a php file in order to save scores, allocute points, etc... Recently, there was a program released that allowed you to stop Flash from submitting the data to the PHP page, change any part of what it submits, and send it on its way.

 

Is there a way to prevent someone from manipulating the data, such as scores and such?

No, once someone downloads your flash game, they can do just about anything they want with it, unless you can find some type of protection/encryption scheme to discourage people from tampering with the HTTP requests. But then they still could run a network traffic analyzer like ettercap that would allow them to do anything they wanted.

So, what you're saying is there is absolutely no way that we could at least 99% protect the data? Something like hiding the score inside a hash or some randomized code that only the PHP script can decode? IE: asdfij1kl3190jda is a score of 31 or something but only the PHP file can decode it (and since nobody can easily download a PHP file and read its contents...)
