Re: Proposal to deal with archiving of I-Ds2000-09-28 10:40:03Hi Bill, Postscript files are straightforward for a postscript hacker to change. I imagine the same is true for pdf files. If you want to make the files hard to change, try a pgp signature. I have no problem with that, but it's not enough. I'm interested in putting something in front of a trade press person that they cannot ignore. Perhaps the watermark should simply be "REJECTED or EXPIRED". Hmmm.... I think this stuff could all be done with commonly available UNIX tools...
