  • How to identify users in video file when streaming video ? [on hold]

    24 octobre 2017, par blackjak231

    I’m trying to find a solution to "secure" online video courses on a video streaming platform. The goals are the following :

    • Prevent easy download of video - OK
    • Be able to identify which connected user downloaded the video if it happens - NOK

    The server will be a Debian machine running PHP 7 and the "encryption" of the video will be done "on the stream" for each user.

    My question is for the second point. I’m unable to find a good solution for it. Here is what i thought of so far and the downsides :

    1. Add a watermark with the user’s name/email with "ffmpeg" on the whole video (in a corner)
      • Can be blurred and therefore useless
    2. Add an invisible digital watermark (inside the video file) with a tool (which i have not found yet)
      • Screen can be recorded and the invisible digital watermark lost.
    3. Add a watermark with the user’s name/email on 2 or 3 specific frames of the video while streaming using "ffmpeg"
      • Best solution from my point of view but no technical solution found so far.

    Do you have any recommendations on how to do this or a completely different approach to the problem ?

    I’m open to any third party video tool such as Vimeo or any other available.

    Thank you in advance for your help ! :)
