Well, no matter how hard you protect it, as soon as you release it there will be people able to steal it (which does not mean they will do it though).

And that's where releasing unobfuscated content helps. When you release some content, attach it a license (whatever it may be) and ensure that it remains available somewhere on the net where it's "history" can be properly tracked. Then, if anybody ever claim your work is theirs, you can sue them and you will win the case.
To be on an even safer ground you can use the old-school artist technique (mostly used by "poor" musicians to make sure nobody can "steal" their lyrics/music) : burn your content onto a CD/DVD/whatever and send it to yourself (through the post office) and of course don't open the package, unless you need an evidence to win a "this is my work" case in court.
