"Clean Up After Your PDFs"

Clean Up After Your PDFs

"...The latest: Like Richard Nixon running amok with his tape recorder, the Acrobat users at the Oval Office weren't quite in tune with the ramifications of their technology: Before posting a 38-page Iraq policy document to the Web—from which the President's speechwriters derived the headline-grabbing "Plan for Victory" speech Nov. 30 at the U.S. Naval Academy—the White House left "feaver_p" as "Author" in the document metadata. Read the story [Greg: No NYTimes registration need if you read it here] to see what developed after that, if you're really curious. ...

There are many potentially embarrassing or unnecessary things one could put in a PDF that could later result in your own "feaver_p" incident. Here are some of the biggies:

Document Metadata
...

Image Metadata
Another interesting place to look for hidden clues about the making of a PDF can be metadata in images, he continues. Some digital cameras actually imprint GPS coordinates (longitude and latitude) of where a picture was taken, in addition to the usual date-and-time stamp. Acrobat can conveniently add this to your PDF without your noticing. ...

Clean Up After a Review
Guess what? If you send a PDF through your company for review and comment before publishing, those changes will remain in the document until you deal with them. ...

Redaction
... "


I've seen people push PDF's "because they are safer"... Well if you don't understand the technology you are using, nothing is safe.

Though I have to admit, the GPS image metadata did grab my attention. Damn, I never thought of that being an issue with PDF's.

There's a good bit of metadata/EXIF tags that can be in a pic from a digital camera, camera phone, etc. And as GPS is embedded into more things, this is going to trip someone up big time in the somewhat near future...
