There's no truly secure way to do this. About the best you can do is encrypt the strings, but people can crack it if they want to badly enough. Depending on how much effort you want them to go through, you can do any number of things to encrypt, from simple to complex.
You might also consider requiring a connection to a server to see if you should run. But given enough interest, you will get p0wned eventually.
