Market-Ticker: 0, TheKansasCitian: 2

Market-Ticker, a blog run by a former ISP owner and which claims to contain “commentary on capital markets” has been going batshit crazy trying to defend his “expert” theory that the Long Form Birth Certificate released by the White House last week is a forgery.  You can view his “evidence” in the following video:

Now let’s get back to reality and address his evidence.

First, he claims when you open the PDF file (you can download it here) in Adobe Illustrator and view the link layers you will see a list of multiple link layers in the file.  The basis of his argument is that if you scan in a document and save it as a PDF it will have no layers to it at all so the only explanation for their existence is if someone manually added them while creating the document.  This simply is not true.

In order to create smaller, faster loading PDF’s Adobe Acrobat and other PDF tools use a process known as MRC compression to identify text, separating it from the background, and saving the text as new vector layers of black pixels.  Vector layers are essentially mathematical formulas for where a program should draw pixels on your screen to form an image.  The benefit of using vectors is it allows scaling of image data quickly while retaining quality within a much smaller file size.  The background of the original document is retained as a single jpeg layer in the new optimized PDF because vector layers are incapable of saving the voluminous amount of data required to render images with 16 million colors or more.

After I explained the technical reasons why the link layers were created Tickerguy held on to monochromatic aberrations in the layers of the White House version of the birth certificate as the foundation for concluding the document is a forgery.  But again this is fallacy.

Here are the simple steps one needs to take to scan and create an optimized PDF which will not only contain link layers, but will have monochromatic aberrations within the text layers:

  1. Scan a document and save it as a jpg image.
  2. Open Adobe Acrobat and select create PDF from file.  Then browse to and select the image you just scanned in the previous step.
  3. Its time to optimize the document.  Click the Document menu and go to OCR text recognition->recognize text using OCR... then click “OK”.
  4. Again lets click on the Document menu, this time select Optimize scanned PDF. Move the size slider to small size then click “OK”.
  5. Finally, save your PDF.

That’s it, that’s all you have to do.  Feel free to duplicate and test at home.

Below are pictures of the PDF test I did using the above steps. One is of the PDF opened in Adobe Illustrator to show the link layers and the other a close up of the optimized text revealing the monochromatic aberration effect.

Quoted from article:
"Note the absence of chromatic aberration."

I think you just proved his point...

Scanned documents aren't evidence of anything even if they are legitimate. The entire reason there is a professional field known as forensic document examination is that a great deal can be told from examination of the original document itself. Much, much less can be told by looking at a photocopy of a document and very little, if anything at all, can be told from looking at a digital image that purports to be an image of an original document. Too much opportunity for adulteration, no opportunity to examine the paper, the ink, any impressions made on the paper, etc. These online arguments discussing images (especially photographic images) are like people studying animals by examining imitation scat.

Why? Because it's worthless as a legal document.
There ARE NO: Hawaii State Seals, No Witness Signatures, No Statements of Certification, No Validations.
