Hi y'all, the original Adobe Reader supports a lot of DRM functions like different passwords for printing/low-res/cut'n'paste, and, at least with their big'n'honkin' Enterprise solutions, time-limited documents that cannot be opened after a date.
I've been searching for hours and hours, but i could not find any evidence that this is possible with the PDF Standard. Does anyone know if the pdf library in djigzo does support any of these features (beyond the already implemented encryption)...? Personally i'm looking for the timebombing-function to send CV's when i'm applying for a new job, and i don't like the idea that my CV is circling the int[er|ra]nets 'til the end of time. I could image three ways this could work: - Simply check the time of the computer (yes, easy to circumvent; but most HR-People i've met would not even be able to do that ;)) - Check the time of a certified timeserver - Get a needed decryption-key from a (djigzo-) web-server, which could be disabled after a timeperiod (yeah, that would not be a simple feature, but it would be cool, it would be possible to track if/when/how often a document/mail was opened, revoke that right at any time, potentially chance permissions like print/no print on the fly etc) Any ideas if something like this is possible with "official" pdf commands, or, if not, if it could be implemented with javascript inside the pdf...? Comments, flames welcome ;) Regards, Jay _______________________________________________ Users mailing list [email protected] http://lists.djigzo.com/lists/listinfo/users
