Flash Video Security.

Hello there...

I'm trying to protect my customer's video content by using the following
methodology:

Develop a flash player (swf) which need to do the following steps once loaded
to the client:
1. Get a private key (a string for decryption) from a given server and
load it into memory. (never save to Hdisk).
2. Get filename, path and size form the server.
3. Measure connection speed for buffering purposes..
4. Buffer encrypted video&audio data INTO RAM ONLY (never to Hard Disk
!!!). [Note that the data is an flv file in
the server). - Of-course, best buffering is the entire video file up
to a size of ~32MB.
5. Decrypt some buffered data (while further buffering - of-course).
6. Display buffered data (play video).

Well, as you can see, I'd like all object (especially the video contend) NOT
to be saved on the hard-drive, but only in RAM !!
all operations are done in this player, so there is no streaming at-all - thus
no "streaming/media server" is needed (or wanted) here.
The problem is that most "regular" players do buffer the files to the disk and
this is very dangerous for us...

Oh, our system is: Linux Debian, and in addition to flash we use PHP+JS
(+AJAX).

So, how can we do it using flash-only ?

Thanks in advance..

i dont think that is possible - you will need true streaming -
and then all the user need is a stream ripper of sorts.

there will always be ways to copy stuff from the client side, as the data have
to go there for the user to see/hear.

you can make it difficult for the average user - but that is not who you
should be concerned about anyhow.

only way is to not publish, if you dont want people to get at your files - or
adapt the business model (radiohead)

As andersen stated, there is NO WAY no guarantee that the client cannot get the
data. Even if you were physically able to create a player as stated in your
steps, the end user would only have to run a screen recording software, and
they have the entire video.

Also, I must say that it is a surprise to find anyone using Linux that is THIS
concerned with protecting their content... I say, embrace the open-source,
embrace the business model of radiohead.
