I have only just now read the Garrett Papit research paper written for Arpaio’s Cold Case Posse
“Comprehensive Analysis, Obama LFBC PDF file”
http://www.mcso.org/MultiMedia/PressRelease/Media%20Supplemental%20Report.pdf
The one main point that NBC appears to have claimed to debunk in Papit’s paper is that MRC (and Papit DOES discuss MRC compression in great detail)...MRC “should” only create ONE 1-bit (black) text layer and that nearly all the text and lines as well as the date stamps and signature stamps “should” be contained in that one layer.
NBC has not yet refuted Papit’s claim that there should be NO halos.
Papit explains:
“The presence of a white halo around the text, and white space beneath the text, on the White House file is inconsistent with optimization or a simple scan. Under normal circumstances, a scanned document will not result in an image that has a white halo around the lettering. Similarly, optimization will not arbitrarily add a white halo or insert white space beneath the text layer. In order to generate such a halo, a user would have to take deliberate action, such as applying an unsharp mask, within a graphics editing program such as Photoshop. Manual editing with such an application would dramatically erode the provenance of this document.”
In this paper, Papit says he created a “control document” described below and this is what it appears he sent to NBC because it was explicitly created to not have the halos that are in the WH pdf but would NOT have been on the original IF THERE WAS ONE. The WH pdf copy cannot be used to simulate an original because it already HAS Halos, thus the need to create a control simulated original without halos:
Papit: “In order to adequately test and analyze the effects of optimization, a control document was created that would be as close as possible to a birth certificate issued by the Hawaii Department of Health. The form data would have been printed onto green safety paper, and then the date stamp and registrar stamp would be manually added via a traditional ink stamp to certify the document.”
I’m scrambling like crazy to get a million things done. So if you or anybody else can double-check my understanding of this, it would be very helpful.
Number substitutions happen on what machines? Do they happen on the default setting for the machine, or do you have to lower the quality and file size to get number substitutions? Did Xerox set up warnings for the user to know that substitutions could occur with those particular settings?
What settings are required to create an automatic clipping mask that takes off the outer edges of the scanned document? What settings create multiple layers, and are the layers created reproducible each time, or are they seemingly random? For instance, you lay the paper on the bed of the scanner. Then you press scan 5 different times, one right after the other, changing nothing and not even opening the lid of the scanner. Do all 5 scans give you the same layers - a reproducible result you would expect from a machine carrying out exact algorithms in a controlled setting? If you save a scan on the 7655 without previewing it, is the saved file different than if you preview it on the 7655 before saving it? If you send the scan directly in an email is it in PDF format? If they open it on a PC will they be able to move around pieces of content? If they open it on a Mac will they?
If you import a digital file to the copier does the copier make layers out of a digital file as well, before printing it?
Seize. I just went to Dr. Conspiracy’s site and believes Garrett Papit is trying to trick him pertaining to the halos. See the red Update. Kevin Davidson aka Dr. Conspiracy says the security paper lines don’t match up and he has images up proving it. Have a look and what are your thoughts since you are keeping up with their experiments?
