[pdftex] OT: PDF Security

[Michael Chapman]

It's off topic, but seems to be hitting the news this morning (and as 
commented on an other thread the usability of PDFs now and centuries into the 
future does come into play ...)

"Copy-and-Paste Reveals Classified U.S. Documents

"In March, U.S. troops in Iraq shot to death Nicola Calipari, the Italian 
intelligence agent that rescued the kidnapped journalist Giuliana Sgrena . 
U.S. commission on the incident produced a report which public version was 
censored for more than one third. Now Italian press is reporting that all 
confidential information in the report is available to the public, just by 
copying "hidden" text from the PDF and pasting it in a word processor."

The 'before' and 'after' are available at:

The 'redacted' version was made with "Acrobat PDFMaker 6.0 for Word"
with ... yes, you're ahead of me ... with "Security Method: None".

The producing agency is the same that banned all web (http) connection from 
France Telecom because allegedly/apocryphally they thought their security 
couldn't resist French schoolboys . . .
