The following pages present a series of proof-of-concept tests for protecting a DCR from unlawful linking, using a variety of different techiques. No single techique is perfect, so it is advisable to implement all possible techniques. The ones presented here are not intended to be an exhaustive list - a more comprehensive tutorial will be added later.
Each page has a test movie to demonstrate a particular protection method. The test movie will show either "access granted" or "access denied". In theory, if you are attempting to link to the movie from another domain, it will always show "access denied". Otherwise, it should always show "access granted".
Contents
IP address method >
This method ensures that movie will only be accessible if the IP address used to access it is the same as the IP address used to load the container page. EvalScript method >
This method ensures that the domain of the holding page is correct, provided that the browser is IE running on Windows. This gives 95% coverage, so it is a good technique provided that there are no compatability problems with other browsers.
