Tripredacus Posted March 30, 2011 Share Posted March 30, 2011 Do you like those movies where the characters have to figure out some kind of code in order to solve some mystery or get some place? Well those types of code exist in real life, but sometimes they can be nearly impossible to figure out. Want to give it a try for yourself? Well there is an unsolved murder case where the victim had "encoded" notes in his pocket. Its been over 10 years and still no one knows how to decipher them. I gave it a shot, and ended up with a headache. Sure I can see patterns in there but can't make heads or tails of it. The victim was said to have come up with this technique when he was a child and authorities are hoping that if they are deciphered, then they can get a glimpse into his past just days before he was found, or maybe even identify a suspect.You can see these two notes here: http://www.fbi.gov/news/stories/2011/march/cryptanalysis_032911/image/galleryNote: some members outside of the US may or may not be able to go to this website.

Glenn9999 Posted March 31, 2011 Share Posted March 31, 2011 The headache part for me is deciphering that writing. Other than that, for a simple letter substitution (which is what it would about have to be for someone to write that without the aid of computing machinery), I'm surprised that it hasn't been cracked. Worse come to worse, there isn't that much text there that wouldn't eliminate a brute force solution (substitute letters, write to text, then look at text to see if its intelligible). In a way, though, if they're going to ask the public this it would be nice to know what they HAVE tried. Link to comment Share on other sites More sharing options...
Tripredacus Posted March 31, 2011 Author Share Posted March 31, 2011 That's true, but wouldn't that be a bad idea? Would the FBI really want people to know all the techniques they use for code breaking? Probably not. I am going to guess that they tried all the applicable types on the wikipedia page for cryptanalysis, plus probably some techniques that no one knows about.

I really find it all strange. You'd think they'd have the smartest/most knowledgeable people in this area and would have the best ideas already tried instead of putting it out to a public that is arguably even less knowledgeable than they are. Besides, we don't even know if it's just a bunch of random letters that this person started writing on notes just to mess with people. As far as we know, this person might be having a big laugh now with people thinking that it is actually anything. Hard to know for sure. Link to comment Share on other sites More sharing options...
buyerninety Posted February 7, 2013 Share Posted February 7, 2013 (edited) Yeah, you'd think they would have recovered more than just 2 examples of code -what about left impressions from the guys notepad/papers/book covers in hisresidence?They also COULD HAVE removed the recovered fingerprints that obscure thelettering!, & give out basic information such as;- left or right handed, can handwriting experts say if he was printing across fromleft or right, and from up or down, do impressions show which of these noteswas filled out 1st (or one folded & concurrently overlaying the other -on this pointI mean that multiple straight definite folds in 1st paper would indicate that part ofeach page was simultaneously referred to and concurrently transcribed by the guy-to give a 'two part ' code i.e. part of both pages contain the encoded wholeof a single encoded message - if this is the case, would also explain why the 2ndpage is clearly divided by borders [?each border=one separate msg/note?] ).To me most importantly where initially he started writing from!If you had that start point, you could follow along the printing, trying to figure asyou go -after all, the guy had to be thinking hard as he wrote the code.[Admittedly, it looks like it starts from left due to left justification of margin of paras& writing is non justified on right side of lines.]I think maybe one note is 'T' heavy?, so perhaps he was tossing in false lettering(filler) as he went. (Handwriting experts should be able to form a view if certainoften repeated letters appear 'thinner', which could indicate (quicker?)writing as'toss it in' filler, compared to thicker lettering, more carefully printed, maybe morelikely to be code. Thinner lettering you 'might' assume may be more easilyprinted - & if its only a 'tossed in filler' character/symbol, you'd think he wouldn'twaste time making filler from more elaborate characters, not consistently anyway.)-Also, note the 'close bracket' symbol [see printed on your 'zero' key on an englishphysical keyboard] may actually be an integral part of the code - notice how theguy takes the time to correct his outlined border on the 2nd page with a definitestraight down stroke, overwriting that bulge in the border that 'could' have beenmisinterpreted by him on readback as an additional 'close bracket' symbol. -A HIGHER base resolution pic can be viewed on the wiki page - unfortunatelystill with the recovered fingerprinting marking still obscuring it partly.Cheers Edited February 8, 2013 by buyerninety Link to comment Share on other sites More sharing options...
