How to protect your Flash / Flex SWF with code?

I wrote some fancy Flex application that really doesn't require server-side integration.

Now, if someone took this SWF and put it on their server, it will work very well.

What code can recognize that SWF is not under my domain and stops executing at startup? I don't mind some server-side calls to check. But how can this be achieved?

Check out loaderinfo.url , he can do it for you. Here is an example of how it can be used to determine where the SWF is loading.

So, you can find where swf is loading from, and if it isn’t from your server, block the good stuff. :)

Good luck.

Why don't you just watermark your app? But I think that if someone steals your application, he will also crack it in order to remove any protection.

As already mentioned, the bottom line is all that you can insert, baddie can break right away, so all you can really do is do the work necessary for this, an obstacle for anyone who even tries. What has been proposed so far will at least remove the random thief, and maybe that’s enough.

The way I found around was that there really was a pretty tight integration with the server-side data, so even if you removed all this integration (which is likely to take several days ... it large application) will still not have any data with which you can use it. It clearly depends on what your application does in the first place, but if you make an architectural decision to move any data to the server side, this will increase your protection.

(This should be a comment, not an answer, but a post here because of the length.)
