Douglas Vogt versus Xerox Workcentre

Dr Conspiracy has a nice selection of postings on Douglas Vogt

Douglas Vogt testified in Georgia, the judge was not impressed

“The Court finds the testimony of the witnesses, as well as the exhibits tendered, to be of little, if any, probative value, and thus wholly insufficient to support Plaintiffs’ allegations.”

Douglas Vogt insists:

I have irrefutably proven that the Certificate of Live Birth that President Obama presented to the world on April 27, 2011 is a fraudulently created document put together using the Adobe Photoshop or Illustrator programs and the creation of this forgery of a public document constitutes a class B felony in Hawaii and multiple violations under U.S. Code section Title 18, Part 1, Chapter 47,Sec.1028, and therefore an impeachable offense. When this comes to the public’s attention, it will be the greatest scandal in the country’s history–”nothing comes even close. This will surpass the all previous scandals including the Watergate scandal of the Nixon administration.

Compare this to the findings that a Xerox 7655 Workcentre creates a document with exactly the same artifacts.

What now Mr Vogt? Surely you must be able to get your hands on such a Workcentre and show that I am wrong?

So far I have shown that:

  1. A workcentre, through edge erase, creates a masking layer, just like the one found on President Obama’s PDF
  2. A workcentre creates using MRC and JBIG2 compression an optimized document which recreates at least the folowing artifacts
  • Multiple monochrome bitmap layers
  • a JPEG layer at half the resolution of the text layer
  • Color under the text layer due to JPEG artifacts
  • Rotated images
  • A JPEG with embedded comment ‘YCbCr’
  • JBIG2 compression causing characters to be identical
  1. When saved as a PDF in preview, after a 180 degree rotation, the relevant metadata identifying the workcentre disappears but various tell-tale signs remain

  1. Aha — I’ve always thought that, given the way mail and image file handling on Macs is set up, it was very *plausible* that the document would be opened in Preview and then resaved before it was posted to the web.

    The need to rotate the image before posting bumps that up to a near certainty.

  2. I think it would be a good exercise to go back and examine the CCP report where Garrett Papit claims that the WH LFBC PDF cannot be the result of common compression algorithms. He claims they ruled out MRC compression. This is from their conclusion on page 29:


    1. The layers are more logical than would be expected from a computerized
    optimization routine. In particular the date stamp and registrar stamp, the very
    items that give validity to the document, are on their own isolated layers separate
    from the background.

    2. Optimization only creates a single 1-bit transparent text layer consisting of the
    text and graphic elements of the image. By contrast the file posted on the White
    House website has several 1-bit transparent text layers. These extra text layers
    include the state registrar’s date stamp, state registrar’s signature stamp, portions
    of the registrar general’s date stamp and most of the local registrar’s date stamp.

    3. The lines of the form itself are on the background image layer instead of being
    included on one of the transparent text layers. Optimization attempts to segment
    the image and put any text and graphic elements on a separate layer from the
    background and images. This is so different compression algorithms can be
    applied to each layer to achieve the best results in terms of smaller file size. Not
    only are there too many text layers on the White House PDF file, but they also do
    not contain the correct portions of the image, namely the form lines.

    4. The color properties of the text layers are not what would be expected from optimization. Adaptive Compression used by Adobe Acrobat Pro, converts any color text to grayscale black when it segments the image. With this method all text is the same grayscale color value. On the other hand MRC compression, which is utilized by many other applications, actually retains the full color variance of the text. With this method the color can vary from pixel to pixel and contains RGB color values. By contrast, the PDF released by the White House has only one single, non-grayscale, color value for each text layer. This differs
    from adaptive compression in that the text is not grayscale black, and differs from MRC compression in that the text is only one color with no variance. In addition, two of the stamps on the document contain two different colors despite having supposedly been created from one stamp with one ink color.

    5. The existence of a white halo around all of the text on the White House PDF file
    cannot be explained by optimization. Neither adaptive compression nor MRC compression yields these results

    Which of these can we now say have been disproved?

  3. Point (1) is selective viewing of the data. He refers to “the” date stamp, ignoring that two other date stamps, the ones within the form, were not isolated. What he’s “proven” is that isolated things can be isolated algorithmically. And in fact…

    Point (2) says that very thing. What we see in the document is that the algorithm could not isolate text that overlapped non-textual elements.

    His incredulity (and really, as we’ve known from the beginning, the heart and soul of the “PDF is a forgery” claim is argument from incredulity) that an algorithm might break this into several elements (not “layers”) does not rule it out, despite his flat claim “optimization only creates a single 1-bit transparent text layer” . Well, guess what? 🙂

    (3), (5): more argument from incredulity. Dismissable as such before, completely refuted now.

    (4): actually explains point (2) — and (1), really. The algorithm has created separate elements for each color it found.

    Nicely done, Garrett. I’ve seen many, many places where birthers wind up unintentionally refuting other birthers; here, we see a birther refute himself in the same document!

  4. All of them.

    Let me start

    1. The layers are more logical than would be expected from a computerized
    optimization routine. In particular the date stamp and registrar stamp, the very
    items that give validity to the document, are on their own isolated layers separate
    from the background.

    Stamps come in their own color which the software easily identifies as requiring its own bitmap. But again, it’s not perfect as one of the stamps is incompletely separated.

  5. The need to rotate the image before posting bumps that up to a near certainty.

    Yes, all of this fits together so nicely and compactly into a very simple workflow. Just as I had predicted.

    But I am open to corrections or rejections of my findings. Let’s see if the CCP will do its assigned duty…

  6. Is there any chance of getting confirmation of the use of a Xerox 7655 WorkCentre directly from the White House Communications Office?

  7. We know that they have at least one such machine as it was used to scan in president obama’s tax returns.

    Maybe I forgot to post on that one? Look for a document with POTUS in it…

    Oh well, let me find the docs, to further ‘rub it in’…

    These are the documents Orly used to establish the SSN.., So close and yet so far….
