Protection of online video, from downloading

Question

Video

Good afternoon. There was a task to Protect video content from copying.

There is a site, in the closed section of which the user can see the form, now in flv
(which is very easy to download)
It is necessary that the user does not have such an opportunity,

Poke where to dig.

Thanks in advance.

Answer 1

If someone sets out to download, they will download anyway. What can be viewed can be downloaded by definition.

Answer 2

If for an adult, then:
1. the player receives a secret key at startup (via https)
2. a signature (secret key + timestamp + url combination) and a timestamp in an additional header are added to all all playback requests
3. the server decides based on such a request what to do.
4. optionally - encryption of the stream itself using the same key
Theoretically, the bottleneck is obtaining a secret key, here it is necessary to investigate. Maybe the flash gurus will tell you what options there are.
This is used in MAC Access Authentication
If it's simple, then many flash players have modules for secure streaming, I advise you to first look at them.

Answer 3

It’s interesting: when will the questions from the category “If I only look at sites, the traffic doesn’t go?”, “How to reveal a secret to a girlfriend so that she doesn’t blab to everyone”, etc., stop?

Answer 4

I don't think there will be any other answers. If the user can watch, then he can save, and you can only complicate this task for him.

Answer 5

On the way to complication, you can put the flv request with a mandatory post indicating a one-time token and checking cookies. This will allow you to get rid of the most trivial ways of jumping, and if someone writes a ready-made plugin for this, then no one bothers you to change the way the token is transferred to the player once a week.

Answer 6

You can say that I work in this area.
The only option is to write your own player that will understand the encrypted stream. The encryption key must be non-retrievable, ideally on the storage device. But even this option does not hurt to capture video directly from the screen, respectively, in your player you also need to deal with the appropriate software.
IMHO, the game is not worth the candle.

Answer 7

The other day I looked at what kind of protection one of the sites of licensed video content uses. Their task is partly similar (and partly to convince copyright holders that the content will not be downloaded). Use flash access . The link has a link to a brochure with features. The disadvantage is that the video from this site did not start for me. Why - I didn’t understand, maybe the firewall or antivirus misunderstood the good intentions of protection.

Answer 8

If they want, they will rob it from the screen with fraps, and you won’t think of anything against it :)
