MMaschin: NBCs argument is easily shown to not be valid, because if that was the case, then the perfect place for this to have occurred is in the security background layer.

The security background layer is recognized as a colored background and is almost completely separated as such. Since it is compressed with JPEG, there are no JBIG2 artifacts.

MMaschin: That IS a contiguous, repeating pattern. Are we to believe that a computer process found two hand draw, ink on paper, and photocopied boxes similar enough to replace one with a copy of the other, but it did not find a pattern in the security pattern background? If what NBC says is true, then the compression occurred AFTER the image layers were separated, because if you look at the image as a whole the boxes are very different when you considered the content inside the boxes.

That is the whole point of Mixed Raster Compression, the colored background is compressed differently than the foreground ‘text’.

MMaschin: This means that even analyzing the background layer by itself, this compression algorithm was incapable of finding a repeatable pattern.

MRC does not look for repeatable patterns, it only happens when the foreground bitmaps are compressed.

MMaschin: What NBC is saying is not taking into consideration that this must be a systematic process,and not a logical one. If you say ‘this was done here’, it must hold true for the entire document, you can’t cherrypick

I am consistent in my hypothesis.

The image is scanned, and segmented into a background image and multiple foreground images. The background is JPEG compressed with relatively high quality reduction and then subsampled to half the resolution. The foreground bitmaps are JBIG2 compressed (which encodes repeating patterns).

Hope this clarifies. These are excellent questions and I thank you for contributing to testing my hypothesis.

  1. So far we haven’t seen any PDFs that come close to the White PDF. Yes, NBC did release one but it was quite a bit off in reproduction. NBC had his chance and couldn’t deliver. Future PDF could very well be manipulated PDF for the Obot’s own benefit. NBC is part of the Fogbow. There is a history of Fogbow manipulating some the birth certificates to discredit birthers. I would say, I couldn’t really trust NBC at this point. After releasing a failed PDF and with a FogBow history.

  2. I think I have seen the two most astoundingly stupid statements made by Birthers today. First was the one that John (jy1977) just made that “So far we haven’t seen any PDFs that come close to the White PDF. Yes, NBC did release one but it was quite a bit off in reproduction.” That comes from John who has never done anything. He has never explained how the forgery was done, demonstrated what software was used, or what the source documents were used.

    The second was from Butterdizillion at FR where they are apoplectic about NBC’s research. She learned about the problems with JBIG2 and that Xerox WorkCentre’s are actually connected to networks so she figured out how NBC stumbled across the MRC compression

    Something else that just briefly crossed my mind. Somewhere it mentioned scan-to-email capability on these machines. If the machines affected are all ones that connect to a phone line/internet and updates/patches are done by internet/phone line (as seems to be the case, according to the article by the German researcher who discovered this glitch), then it would have been easy for somebody to update these machines so they would act this way just in time for NBC to “discover” that the PDF was created on a Xerox machine (information which ought to be shown on the document’s properties anyway – something I’m checking but I have to do it on Explorer and now my computer is moving slower than molasses. arrghh. Now IE cannot display the webpage. Gotta close Adobe… OK it was produced on a Mac. So that’s why they have to talk about it being emailed. If they had treated Obama’s BC the same way they treated Obama’s tax forms, etc, it would have shown the same properties as his tax forms. So why was this not done on the White House scanner, since that is supposedly where the real 3D BC was at?)

    That would explain why nobody has “noticed” this problem in the past 10 years…

    So you can quit researching NBC. This was all caused by a firmware patch downloaded to every single Xerox WorkCentre in the world when they heard you were looking into the LFBC PDF issues. You are one very powerful dude, NBC!

    The response by the ultimate loser. And please do not trust me, by all means, show that I have been wrong..

    Knowing your history, you lack the skills and expertise to do so my dear friend.

    Sadly enough not all Xerox WorkCentres are accessible for updates from the Internet as this is a separate feature from the email feature.

    Just a little knowledge can be more dangerous than no knowledge at all.

    We have all seen recent examples of that on my blog.

  5. I know at my company you cannot even email directly to an email address outside the firewall. I have to scan and email to my company email address and then forward the email to someone outside the company. I am absolutely certain that the IT group would not let a WorkCentre have access to the Internet. I seriously doubt the machines are ever updated once installed. If updates are required they would be done by a tech with a laptop connected directly to the machine.

    I thought Butter’s ruminations were really funny.

  6. I thought Butter’s ruminations were really funny.

    Well she has questions and before we let her unfamiliarity with these issue lead her to make illogical claims, I believe it to be helpful to set her straight.

    Most companies that would use Xerox WorkCentre machines are very likely behind firewalls, of course, the machine could update itself by contacting the outside world and install new versions.

    A lot of this however is dealt with through service contracts and as you suggested, the service person will be responsible for the updates.

    Still, her scenario is not fully without merit as I am sure some machines could have been reached this way. Including the Xerox WorkCentre that was used to scan in the Tax Forms… Oh wait, that was a few weeks before the LFBC was scanned…

    There are just too many Xerox WorkCentre created scans that such an approach would invariably fail.

  7. RC, does your company’s WorkCentre have a phone connection? They used to be used to “call home” for billing purposes.

  8. I believe that the scanner/printer can also serve as a fax machine, so it likely has a working phone number. Good point.

    No, these machines are generally leased or owned and there is no per copy charge. There is no phone connection tot he WorkCentres and similar machines. The Fax function is disabled. Hardly anyone uses Faxes any more. They are going the way of the buggy whip. There are a few dedicated fax machines around somewhere but I would have to hunt for one.
