top secret documents with info blacked out

[pontifex]

What do they use to black out the information?

I know Sharpies and Marks-A-Lot permanent ink markers do not completely black out text. you can still read through it up close.

Black it out, make a photocopy, there you go.

Could be blacked out then photocopied, or printed blacked out (using the highlight tool). There are many ways.

Actually I've had issues where text was still readable after sharpie+photocopy (I was sending some CC statements to the insurance company, nothing top secret).

I think it was because I printed it out on a laser printer which still reflected some light through the sharpie.

I'm sure the gov't has some foolproof method of doing it, like using a ink-jet printer.

What, you want the blacks out?

Or electrical tape, then photocopy

OCR redaction is usually used nowadays. When redacting by hand, make a copy of the original, use whatever method you want (black marker, scalpel, or tape), and make another copy.

this is what we do. and we use marks a lot markers for it, sharpies dont give that broad line like they do.

I always assumed it was Giant Squid ink.

Wow, what perfect timing.

I am doing a report on censorship in group dynamics, and we will be on campus filming people regarding the issue. While doing research I found a ton of documents that were blacked out, as well as sites that showed how to read the blacked out material. I didn't visit any of them, but I imagine if you put black over black (black being the type), and white (being the paper), the black/black would still be darker than the rest. Unless you use a computer program to alter a document, or scissors, I don't think blacking out areas with a sharpie will completely do the trick.

Google "government censorship in media" and you should find the same links. (You can also go to the CIA site and read the recently declassified documents with all the blacked out areas.)

Originals are never blacked out. a copy is made, blacked out and, another copy made at 100% contrast. The black/black areas are not darker than the rest.

It's top secret.

China has knocked off a Small Hardon Collider, handy travel size. The paper doesn't even exist in those areas anymore.

Can't you just undo (cntrl + z) the black out?

Yarrrr, I don't think "CTRL + Z" works outside of your magic sorcery box. Were it did, I'd still have me hand, me leg, me eye, and me booty (me financial advisor told me to put all me treasure in Lehman... yarrr...).

Also we don;t shread as much anymore, we use burn bags. Fill them up then seal them and they get burned.

I've always used burn bags.



And they generally got taken to a shredder still


Particularly for the sensitive stuff where you had to sign for destruction of.
