Naughty!
My company often uses password protection on pdf docs to prevent others from changing them (eg: a price list) or easily copying proprietary information, prersentations etc. I've even seen documents which forbid printing, which seems to be going a bit far, but the point is there are legitimate uses for password protection. I'd like to know what this does to a pdf that's been electronically signed... Better watch out, or the lawyers will getcha.
Possible recovery method
As always it can be seen from two angles...
Possible recovery method
This hint doesn't seem to work in all cases. I have my tax returns saved as encrypted PDFs that cannot be viewed unless you have a password. ColorSync Utility opens them up as blank pages and saves them as blank pages in Mac OS X 10.4.3.
Possible recovery method
No, this is not a possible recovery method.

This is the Major issue with DMCA. Unfortunately, it is 'illegal to circumvent any copyright protection' and I am sure that this is true even for the original copyright holder as the law, as currently written, speaks to the action of breaking down the 'lock' that is in front of any data. It is at this point in the law that it gets ugly.
So, for example, you are allowed under Fair Use rights to copy any DVD for backup, but since you have to crack the DSS encryption to do that, you have broken the law even if the underlying data is your to protect.
Possible recovery method
Yeah - but if it's your own original work - are you going to bring charges against and prosecute yourself? |
