I watched the video in the OP.
Can someone explain to me how a document that has been scanned into a computer would come up as layers upon layers rather than just the single image that was scanned?
My daughter scanned in a pic she drew and while she can brighten it or color it or resize it, etc., it's just one image, there aren't any 'layers' to it.
The investigator is saying that Obama's BC is in 8 or 9 links and layers and that each layer can be taken apart on the computer . . that the entire document was built and exists in cyberspace, never a 'real' document was scanned in.
They compared it to a controlled document that was scanned in and the two are not the same.
How can that be?
Didn't Trump's wailing about this have Obama reveal this BC just before . . like a day or two before . . OBL was killed? I remember the BC was a big deal then bang, OBL was dead and no more BC talk. It all just seemed to disappear.
Now this?
So can anyone answer my question? How does a document that has been scanned into a computer come up as layers upon layers rather than just the single image that was scanned?
I've had a limited amount of experience with scanning documents, but I'll take a shot at answering your question. First of all, as you've pointed out, when you scan a document, you will normally get one layer in the resulting image file. I've done this before, scanning pages from a text book. The resulting file is not quite the same as the original, though, in that it's an
image of a printed page, and not text. It's as if you had taken a photograph of a printed page, in other words.
So, when it was originally pointed out, that the latest BC had multiple layers, it was suggested that the original scan had been subjected to OCR (Optical Character Recognition) software. OCR software is used to scan a file, to see if there are recognizable fonts forming characters; it will also form multiple layers to assemble a document that you could edit with any text editor.
The first task was to determine whether the WH BC had been subjected to OCR software. There were three tests the experts devised to verify this: 1) Does the document recognize fonts? 2) Can you search for a word in the document? 3) Can you edit a word in the document? The WH BC failed all three tests, proving the document had not been subjected to OCR software. Next, they deliberately subjected the document to OCR software; the resultant document passed all three tests. It also produced 45 layers.
There's a difference in the way a computer generates layers, and the way a human being would produce layers, though; a computer will generate as many layers as it needs, to assemble the resulting document. Complexity means nothing to a computer; a human being, on the other hand, will strive to create a manageable number of layers, knowing that the end task will be to assemble all of the component parts into a single document. Even if you concede that different OCR software products would create different numbers of layers, a complex document such as the WH BC would produce many, many layers. The WH BC had only 9 layers, strongly indicating that a human being manually assembled the document from component parts.
I hope that helps.
