Picking Up the Pieces

ravenousbugblatter writes "The New York Times online ran an article yesterday titled Picking up the pieces that talks about new technology that can recover information from shredded documents. Not only can companies scan strip-shredded paper and recover the information, they can do the same with cross-shredded paper. It comes at a price though - one company charges $8,000-$10,000 to "reconstruct" the information in a cubic foot of cross-shredded material. How's it done? The shreds are glued onto a piece of paper and then scanned. Software then looks for matches (in one case using the pattern of ink at the edges of the pieces) and suggests possible combinations to the operator that can be accepted or rejected."

Shredding is for wimps.

[Anonymous Coward]

That's why I always dissolve my old paper in concentrated sulfuric acid.

[vasqzr]

I eat my shredded paper in a bowl with milk.

mmmm, fiber

We all do that, but most of us do it in prepackaged boxes bought at the supermarket labelled "breakfast cereal" or "shredded wheat" ;-0

In the Canadian Forces it was regular practice in the field to simply burn any document that had a classicifaction higher than Protected A (pretty much Confidential and above). I've had to do it more than once. Of course, burning isn't enough, you then need to pulverise the ashes since you can often still read from the burnt paper.

It wouldn't phase me it we found out the NSA has a method of determining the contents of a document by reading the smoke that is generated as it burns ;-)

Actually, we in the intelligence community prefer to scan the target's cerebellum as he/she is in the process of reading the document. Not only do we get the document in question, but we also learn its pertinence at the same time. Once in a while we get a bonus, like a nice new recipe for Poutine.

If people only knew...

[creative_name]

...they were shelling out $8,000-$10,000 for some dude to sit in a room with a couple of cases of crazy glue and a knack for deciphering ink blots...

Crap! my secret's out.

DOes this violate the DCMCA?

[Unknown Poltroon]

I mean, isnt shredding a type of encrypton? And isnt this reverse engineering?

I think ive mispelled every word in here.

Impressive

[jhines0042]

But I guess thats why the government always burns sensitive papers.

Although... I remembering hearing about a set of government instructions that once said:

1) Destroy all copies of this document once you have read it.
2) But make a copy first for your records.

Re:Simple workaround.

Or you could flush it down the toilet after you tear 'em up.

DO NOT TRY THIS.

I tried to do this with a teacher's note when I was in 4th grade or so. The ripped up little pieces floated happily around and never flushed.

Maybe it will work with a powerful industrial-strength "sounds-like-an-airplane-taking-off" mechanism but, if you're working with a standard home toilet, you're unlikely to get the results you wanted.

Memory holes.

[rice_burners_suck]

For this reason, I don't throw away shredded papers. I had memory holes installed in my home, a la 1984, and whenever I throw away a paper, all I do is throw it in the memory hole and a vacuum sucks it away and into a furnace that burns the paper until it nothing but dust. I mix it with dirt, soil and fertilizer, and then I spread it all over my yard. The plants love it.

Document FLAMER!

[WPIDalamar]

Excellent! Since shredding isn't secure anymore, when are we going to get personal paper INCINERATORS. Put paper in... press button... KAZAAM, 4 foot flames shoot out of the bin.

In related news...

[chad_r]

... Arthur Andersen accountants and Enron executives were reported to have pooped their pants upon hearing this.

Re:Diced documents?

[FattMattP]

I wonder how long it will be before we see the first shredders that slice the documents into squares instead of long strips.

It'll be about 20 years ago. At least.

Re:This is why

[Cpt_Kirks]

For the explosion? I once saw an idiot 2Lt dump a box of 1x2mm document shreds into a blazing burn barrel.

Tiny bits of paper + oxygen + hot flame = Lots of fun (if you're not too close).

Re:Still a good idea...

[Cyno]

I'm not paranoid enough to shred my financial documents. But I'll happily encrypt all my data.

I don't trust you. Its not that I don't trust some criminal who might be after my money. I don't trust YOU. My neighbor, my friend, my fellow citizen. Because I watched you vote.

Re:When I was...

[Salgak1]

I was in the USAF as well. We also had the "powdering" shredder, but OUR SOP was to shred docs, place in the black plastic bag, stop by the Field Maintenance Squadron, sign for a 1-2 gallon container of JP-4, then call Civil Engineering and the Security Police Squadron. We'd all meet at a remote location on base, I'd empty the bags into a steel drum, followed by the JP-4, CE would throw in a radio-controlled incediary thingie, and we'd all retreat 50 yards or so, the cop would make a radio call, and the CE guy pressed the trigger. Big fireball, pillar of flame for 5 minutes, and then walk back up, stir the ash, another gallon of JP-4, and repeat.

I don't even want to THINK what they had to do with the TOP SECRET and Compartmented waste. . .

One has to wonder how much this was dictated by security requirements, and how much is was just because you could.

It's substantially more effecient to just throw your statements out to the street on trash day under your coffee grinds.
Coffee grinds? Bah! As a parent, I have two words for you:
diaper pail
If someone gets my credit card statement, they damn well deserve it.

Re:Still a good idea...

[killmenow]

I don't care about risk analysis. If there's a chance at all, (as others have pointed out) you can get a shredder for ~ 20 USD. I told my aunt to buy me a crosscut shredder for Christmas or something so got it free.

Besides, the cost and the risk are not the point (for me). I just freaking love the feeling I get when I run solicitations through it. Jesus I love that scrunchy crunchy grinding noise it makes.

I swear my blood pressure gets a few points closer to normal every time I shred something. Paper shredders: they do a body good!

Re:Who's paranoid?

[PhilHibbs]

What I think would be a good solution would be a shredder with a built-in printer

You mean a shrinter?

I'm surprised this company hasn't been sued for violating the DMCA because they are attempting to "circumvent a security feature".

Well maybe if you'd stop leaning over my shoulder while I vote, I'd stop poking through your trash bin.
