Ihave to find a way to make sure that pdf files posted on our website are not downloaded. This is not possible as they DO have to be read by the users. The point is to prevent them from copying them (I know the user right management transfers to the copy as well but that won’t help) the only solution I can come up with is a way to make the file simply delete itself after a given amount of time from the download.
Once it can "see" it is no longer on its home system it would begin a count-down, say 2 hours. That would be more than adequate for someone to read the content and make a decision. Longer than that, if they are that slow to read, they would just have to re-open it.
I know that to even open the file for reading it is downloaded by adobe reader into a temp internet file. So the “clock” would also start as soon as they started reading since that in effect is taking the file off of its Home system long enough to be read. That isn’t a problem but leaving it there would be just as much as allowing an actual download
Opening the file already requires a password. So they have to start over. The main intent is, as I said, to prevent them from literally clicking to download the file.
Nothing in this world is perfect but surely there is some way to come close?
