Sharing with no modification


Is it possible that, when you share a text from an application, do not allow to modified it? I ask this question because I made a game and I would like to share the score I have done but, when I'm going to share it, I see that I can modify the text so, everybody can lie when they share.

You can not introduce a read-only flag to AI2 text files.    You can encrypt the file and keep the encryption algorithm in your app so that it is impossible (well, almost impossible) for others to de-crypt the file.   Yes, you need to develop your own encryption routine  or find a tutorial that shows how to do it with outside resources.
