Defa Protector is a relatively new technology that specifically targets HTML5 video players and allows webmasters to protect their copyrighted materials from being pirated online.
This script lets audio and video files be played via the browser but blocks user access to the raw audio and video files themselves.
In this latter case, content thieves will be served an HTML file with an error inside, instead of the audio or video files they expected.
The Defa Protector system works not only with directly accessed files, but can also protect against automated scripts and download managers as well.
Defa Protector is available as a PHP script that can be integrated into any CMS platform, but also as a dedicated WordPress plugin as well.
Here's a short video tutorial from Defa Protector's own author:
Requirements:
- PHP with get_headers function and $http_response_header enabled
Limitations:
- Some mobile browsers might not play the video.
