Restricting usage of exported SWF files

SWF files can be embedded and played back from web pages and other SWF files that exist in completely different domain than the embedded SWF movie.

You may want to impose security restrictions on SWFs you export, so that they cannot be copied and used on a third party website or embedded within third party web pages or SWF files. The SecureDomain and SecureCode properties allow you to do this - see Using the SecureDomain and SecureCode features for details.
