Apologies if this isn't the right part of Stack Exchange, this seems the right place though.

I'm helping a music teacher friend who lives on private tuition. They want to provide short videos that students can learn with between face-toface lessons but doesn't want those videos getting passed on in the wider world. They aren't looking for a get-rich-quick scheme, the teacher wants to teach one-to-one students.

We've looked at You Tube and Vimeo so far. In the student context I understand this means:

  • Vimeo simply uses password access. i.e. if one student passes on the password then there is no protection.

  • You tube has a feature that requires a student to log in with their own gmail account which has been pre-authorised by the teacher. This seems ideal except that it seems not to work. The user interface accepts one e-mail address and then refuses to add or delete any users.

Question: Are there any other online tools that provide protection to teachers distributing course materials?

Context #1 I don't think they are that bothered about people thousands of miles away getting the benefit. Its more just where it might make the difference between a recommendation from a current student to a potential new one (i.e. very positive) instead becoming "here, use all these videos for free" (i.e. a direct loss of income).

Context #2 Clearly we realise there is no protection from someone using you-tube downloader or something like that other than putting the teachers emblem in the corner of the video.

    If the videos are just complimentary to the lessons, where is the potential harm? Wouldn´t it be better to just release them publicly once you´ve gone to the effort of creating them - getting the publicity as advertising effect for the real product (the lessons)? – Daniel Jul 18 '18 at 13:06
  • @Daniel this is a good point and we've thought of it though its hard to call as a judgement if its an all or nothing decision. The market is for face to face lessons with local students. Its an unusual musical instrument though there certainly is a market. The ideal would be to release some videos publicly and hold back some others and so this question is about how to manage the latter. – Puffin Jul 19 '18 at 12:21
  • You still have the legality on your side to deter anyone to make a profit from your work. Other than that, the DRM-Topic is complicated and even major companies are struggling with it. Sorry I have no good answer other than this. – Daniel Jul 19 '18 at 12:28
  • Anyone care to offer a reason for the -2 received this week? – Puffin Sep 14 '18 at 10:22

One methodology you could use is a page with an expiring link. You would embed the video into a webpage that once viewed will expire. You would need some coding knowledge to do so but the security will be protected that way.
