Hi All

I am creating an application which loads images in swf. Image paths/names are loading from xml. XML will be dynamically generated with asp.net. Users will download SWF, XML and images as a (ZIP) package from our server for multimedia CD or their own website.
My question:
NOW, how can i secure my swf and XML so useres wont be able to add new content by modifying tags in xml? We dont want users to add/modify content by themselves. How can i secure my swf or xml?

P.N. * users will use our package offline!
