I have a flash based game that has a high score system implemented with a SOAP service. There are prizes involved and I want to prevent someone from using FireBug or similar to discover the webservice path and submit fake scores.

I considered using some kind of encryption on the data but am aware that someone could decompile the swf and work out how I did it.

I also considered using an IP whitelist but since the incoming data will come from the users IP and not the servers that won't work. (I'm sure I'm missing something obvious here...)

I know that there is a tried and tested solution for this, but I don't seem to be asking google the right questions to get to it.

Any help and suggestions will be appreciated, thank you
