New Technique Reveals Centuries of Secrets in Locked Letters (nytimes.com) 36

M.I.T. researchers have devised a virtual-reality technique that lets them read old letters that were mailed not in envelopes but in the writing paper itself after being folded into elaborate enclosures. From a report: In 1587, hours before her beheading, Mary, Queen of Scots, sent a letter to her brother-in-law Henry III, King of France. But she didn't just sign it and send it off. She folded the paper repeatedly, cut out a piece of the page and left it dangling. She used that strand of paper to sew the letter tight with locking stitches. In an era before sealed envelopes, this technique, now called letterlocking, was as important for deterring snoops as encryption is to your email inbox today. Although this art form faded in the 1830s with the advent of mass-produced envelopes, it has recently attracted renewed attention from scholars. But they have faced a problem: How do you look at the contents of such locked letters without permanently damaging priceless bits of history?

On Tuesday, a team of 11 scientists and scholars at the Massachusetts Institute of Technology and other institutions disclosed their development of a virtual-reality technique that lets them perform this delicate task without tearing up the contents of historical archives. In the journal Nature Communications, the team tells of virtually opening four undelivered letters written from 1680 and 1706. The dispatches had ended up in a wooden postal trunk in The Hague. Known as the Brienne Collection, the box contains 3,148 items, including 577 letters that were never unlocked. The new technique could open a window into the long history of communications security. And by unlocking private intimacies, it could aid researchers studying stories concealed in fragile pages found in archives all over the world.

  • Were the pages' ties unable to be untied and retied? Why couldn't a snooper simply unbind the letter and rebind it?
  • The history is in the content of the letters, not the form of the letters. Sure, document the original state and carefully take it apart. If you want to, put it back together after conserving the contents.
    • With this method they can have both, and it is interesting to see the letters folded up as they were hundreds of years ago.

      The history is not in the content of the letters at all.

      The history is in:
      > The support (paper composition, animal skin, etc.)
      > The ink (iron gall ink, blood ink, pigmented ink, etc.)
      > The calligraphy (uncial, humanist, etc.)
      > The document structure (rolled, bind, codex, stitch, etc.)
      > The headers, if codex (with core, without, linen, silk, etc.)
      > Etc.

      • Sincerely, I wouldn't care much for a letter from one dead people to other telling about the weather, but I do care for how that person closed the document with the tools of their time.

        Not to mention that since the letter is sealed you don't even know if it's worth reading what's inside more versus preserving the letter itself so that future generations will have some intact samples.

      Also, I forgot to mention that, apart from you being the idiot, some documents can't be opened because of the frailty of the paper (that might even disintegrate by trying to unfold it), for historial reasons (maybe it's closed with a wax seal unique), etc.

    • Something historians have constantly experienced is they will develop new methods to get more information out of artifacts, only to find previous investigations have fucked up said artifacts too much for the new methods to work.

    <clickbait>What the author doesn't know about email encryption may shock you!</clickbait>

    SMTP encryption isn't mandatory; lots of email is sent in the clear, and the NSA is watching. Most providers do not encrypt your inbox at rest. Gmail is absolutely snooping your mail. I'd assume most other large providers do too.

    Decades ago we pushed to encrypt things end to end with PGP, GPG, S/MIME, and such, but most people couldn't be bothered. Others outright laughed at our tinfoil hats.

    • I have recently come to the conclusion that we need a complete replacement for email. Email is 50-year-old technology, and is simply no longer cut out for the task.

      We need an entirely new system build around (for starters) security, (optional, but strong) authentication, and guaranteed delivery.

      S/MIME and the like are an attempt to put lipstick on a pig.

      It's time to replace the pig.

  • Most of the software and hardware technology components presumably were previously developed for scrolls from the Herculaneum Villa of the Papyri, an earlier, much worse geometry and fragility case.
  • Viewing the thing in VR is fine, there's no reason not to.

    But it has literally nothing to do with reading the content, because the software flattens out the page. You might as well just get a JPEG out.

  • I'd never even heard of these techniques for "anti-tampering" letters back in The Day, much less the actual historical use of such techniques!

    Thanks again, Slashdot. Godz, I love this place :-)

  • This virtually unfolding technology may tell scientists more about postal networks in Europe as well. It's an unsurpassed achievement for old letters reading and UK libraries will benefit from it. King’s College London lab reports cheapessaywriter.co.uk [cheapessaywriter.co.uk]

The truth of a proposition has nothing to do with its credibility. And vice versa.
