How to protect a web player game

Question

Hello All! I have finished my webplayer game, but I am worried about people being able to steal my assets. I have heard that Unity can open the important UNITY3D files that are necessary to run the unity webplayer game. I am a noob when it comes to file encryptions and that sort of stuff, so please help!

There is no way to protect your files from hackers, if someone wants them bad enough they will take them. I would suggest some preventative measures such as obfuscating your web build when it's done, as it will help prevent some noobs from just getting the full source code from your game.

Thanks!

Use asset bundles. Implement your own encryption/decryption, then use:

That's probably the dumbest thing I have ever seen, no offense. Encrypting/Decrypting assets through scripts will not protect anything, as anyone can simply de-compile the script to project form using .net reflector, and grab the functions used to decrypt/encrypt.

@xtron32: Not really, it depends on how your encryption / decryption works. If you get the decryprion key from your server, only when your user has authenticated himself and you send him a personal version of the asset it's quite save. You can't prevent a user from copying, but you can watermark your assets so you can tell this is yours and who has copied it. It also prevents unautorised users to access / use the assets.

As we all know you can't protect something 100%, but this at least increases the "protection level".

@Bunny83 It is a decent solution, but still you can simply recompile the de-compiled project, and have a debugger write the assets unencrypted when the key is sent from the server.
