I recreated the FReeper Polarik test using the image software GIMP.
A week ago, I downloaded from the official Obama website "Fight the Smears" Obama's birth certificate. The 'Edge Detect' filter did not show the "embossed seal" on the BC.
Today, I downloaded the Obama birth certificate from the KOS webite, I used the same image filter test to the KOS BC as I did with the one from the Obama campaign website, and walla, the image of the seal pops into view.
Conclusion: the image of the "embossed seal" on the KOS BC is fake.
IIRC, the KOS one never showed the seal. The one from Obama’s site always did.

Do you still have both files?
I need a copy of the “original” image along with one showing the seal.
