Picking Up the Pieces

Posted by michael on from the all-the-king's-men dept.

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 your financial statements is still a good idea. It keeps people from going through your trash and getting financial information. Everyone should at least get a straight line shredder and shred everything that they don't use.

      I would agree with you, but it depends on where you live. If you're a college student living in on-campus apartments, you should shred your documents. I've seen people dumpster diving for financial information in such areas. The campus police had a hard time staying on top of the problem where I lived. College students are good targets because their trash is frequenly mostly paper, they have to put their SSN on just about everything (at least, they used to), and their trash is almost inevitably full of credit card statements and other financial detritus. Combine that with big, shared dumpsters full of bags like that and you have a prime target. Sure, somebody probably isn't going to grab your specific garbage can in the suburbs, but the likelihood of being a target in some areas is quite high.

    Ok I havn't read the story, yet but one quesion comes to mind. How do they handle double sided printing? And if they can't, more the reason to print double sided, besides saving paper.

    This is why sensitive information should be incinerated after it has been cross-shredded.

      Why bother cross-shredding it first?

    Never put all your shreds in one waste-basket.

    Papers that have been burned are usually readable, as long as the ashes aren't totall crumbled into particles. The burnt ink will have a different shade of grey than the burnt paper. It takes work, but you can reconstruct paperwork quite well from burnt papers. In many cases even easier than shredded paper, as the fragments are larger.

    If burnt until the ashes turns white again, it's even easier -- then the text will often stand out in black on white again, and be directly readable by a human eye.

    What I think would be a good solution would be a shredder with a built-in printer -- it will print random text over the sheet before shredding it, to make the text unreadable even if reassembled.
    If anyone hasn't patented it, it's too late now - I hereby declare the idea public domain and knowledge.
