Using a unique key to restrict and protect sharing

You may restrict access to videos in a directory on the basis of geolocation (click here) or by using a unique key for each visitor. This enables you to control access to videos and to authorise certain users only and deny access to everyone else. This is useful for pay-per-view scenarios or for restricted broadcasts. However, you should note that it is your responsibility to build the integration code into your existing system. Here is an example of a key (which you may customise) that might be associated with a directory:

123KEY456

The hash is then generated using the following function:

/**
*@param $sKey Key value available above.
 *@param $sVideoName Video name (name minus extension).?
* @param $sUserIP User's IPv4 address.
 */?
$hash = md5( $sKey . $sVideoName . $sUserIP . date("YmdH") );

Then, simply pass this hash as a parameter to the video. Example: http://vod.infomaniak.com/redirect/.../video.mp4?sKey=$hash

If the hash is invalid, accessing the video will return a "403 forbidden" error page.
