Photo and Document analysis software

[converge]

imo this would make a rocking DC14 CFP entry ... or DC15 if too short on time..

Maybe astcell and I should get together and create a presentation. There was alot of interest locally.

This is actually something I'd really like to see - I've been getting a bit more into stego lately, but have no clue as to how to analyse for changes or the depth of information that can be obtained. Most of the stuff I've found on doing this has been either way over my head or so basic as to not really teach anything useful.

This is actually a topic in planning to be presented locally at our meetings. Someone a few months back had asked about photographic evidence & examination/verification.

How to detect digital editing of files, such as mismatched timestamp between the EXIF data and the file time stamp. How to enhance images to better see pixelization due to editing, what compression formats cameras use, and what compression methods software use. Also included in the presentation would be some history of digital images as evidence in court.

I think he means analyzing a photograph already printed, like in Blade Runner. If you have the negative a lot more information can be gathered than you think.

As for analyzing documents, the Fibbies are the tops on that from what I have seen. They routinely check for flaws in passport design, and that's no small feat. Then again what is it on the document you are trying to analyze? Hand written documents show a helluva lot of information.

Didn't the CIA/DIA have their support for much of this analysis and work moved/merged into NIMA?

Heh. I can imagine a new guy being handed a magnfying glass who is asked to use it on their computer screen.

"What do you see?"
"Umm. Pixels?" :-D

Perhaps the poster is looking for software to analize digital images for hidden data, aka steganography.

No and NIMA became NGA over 2 years ago. NGA is primarily acquisition and dissemination (or they like to say it). Most TLA maintain their in-house analysts.

Any of you guys know of any software specifically designed for in-depth analysis of photographs and documents?

Yes, you may want to take a look at VeriPic Software put out by Kwan Software Engineering, Inc.

You can find more information about them at their website or by sending them an email: Infor@VeriPic.com Just be forewarned that their software comes with a heavy price tag depending on what extra features you may want.



NOTE: I'm not employed by VeriPic and/or Kwan Software Engineering, Inc.

heh, look into MS Magnifier, it makes things larger.

as an interesting side note, this is the same technique used by CIA analysts who examine satellite imagery. they, of course, have to do it the old-fashioned way... with hand-held magnifying glasses and optics.

If anyone can help me out with this enquiry, I would really appreciate it.

Thanks.
