Is it possible to send data from an open-source program but make it impossible for a user with source code to do the same?
If I want to store a global scoreboard for a game running locally on the user's computer and I want to make sure that all the requests coming to the server are really generated by the game and not spoofed by the users, is there anything that can be done to prevent cheating? The program is open-source, so no obfuscation can be used.
The problem I have with coming up with a solution is that whatever I choose to implement in code must necessarily include all the components necessary for creating a spoofed program that can send any data user wants, especially any encryption keys and hashing algorithms used.
