Using AutoGraph to Protect Online Video ​

Intro ​

Xvid AutoGraph is a technology to individually watermark and fingerprint online video. No two viewers will ever receive the same copy! Each viewer or downloader will receive a different, individually watermarked version of the video, generated just for them. And since every distributed video copy is distinguishable, any pirate copy that pops up on BitTorrent or on file-hosting sites can be effortlessly traced back to the original illegal uploader — which creates a strong counter-incentive for spreading pirated content in the first place. You can read more about content protection with Xvid AutoGraph here.

Basic Steps to Enable AutoGraph-Protected Video Distribution ​

In order to automatically generate uniquely watermarked download links for a certain video title from your website, the following steps need to have been done:

  1. An application must have been created in your account and the client_id / client_secret application credentials obtained. The client_id / client_secret will be used to HMAC-sign the AutoGraph download links presented to each user of your site.

  2. The video for which AutoGraph-watermarked copies shall be distributed must first have been imported into your Xvid MediaHub account and must also have been enabled for AutoGraph distribution. This is done by launching a video import/conversion job once (having the "Enable AutoGraph" checkbox marked). After a successful import, a FileID can be obtained for the video, which may then be used to reference the video upon generating the uniquely watermarked copies.

  3. As many individual download links per FileID as you need can then be effortlessly created via simple HMAC-based cryptographic signing of the link (we provide sample code for this, so no worries!). Every download is individually marked by providing a Tag parameter. The Tag may be, e.g., the user_id or username of the downloading user.
