Secured Video Streaming - Signed URL

I am seeking a script to secure videos through the use of signed URL for an adult site. Currently, I am using Flowplayer, Cloudberry Explorer and Amazon Cloudfront to stream my flv. videos, but needing tighter security measures, so the url would only be valid for a couple minutes; Therefore, the URL will not able to be passed to third parties. The URL will be recomputed automatically each time the user wants to play the video(s). Please only bid if you have completed similar work and have experience with the below. Here are some helpful links to assist in the procedure for what is needed: 1. [login to view URL] 2.
