Hi All,

I'm intrigued as to why one would put something on Blackboard and then want legitimate students not to be able to copy it...... or  at least why one would imagine it was possible to protect at all. If it's going to be published, wait until it is.

There's no real way of doing this that can't be circumvented. 
Essentially, if it's available on the web (including Blackboard), it's 
capable of being copied. Such circumventions may get more extreme, the 
more roadblocks you put in the way, but the truly evil mind/bored 
student/someone like me would look at ways around things like this for 
fun (no, really, I do...)

These might include (starting at the most likely):
o Firefox NoScript extension
o Firefox/IE JS/Java being disabled
o Pulling files/text out of browser caches
o Screenshotting the files/text and then popping them through an OCR 
reader to give a proper text document
o Capturing the data stream as it comes down and rebuilding the file 
from that. This is doable, but needs a hell of a lot of work, so isn't 
likely to happen, moreso (ie it's impossible) if you're running 
Blackboard in a secure environment (ie through SSL).

If you're interested, I've done quite a lot of work in content/copy 
protection, primarily of images (jpegs) in another project I'm involved 
with, so would be happy to talk more about this. Contact me offlist if 
you need.
