Digital camera fingerprinting...
by Dave Emery 24 Aug '04

24 Aug '04

Just a random distraction from the normal topics (but not completely irrelevant either)... I happened to spend a few minutes yesterday talking with an individual who participated in the development of both low and high end digital cameras for the commercial mass market. He told me that especially in the low end camera market NO sensors used were completely free of anomalous pixels (black, white, dim, bright etc) and much of the actual processing in digital camera firmware was related to masking or hiding the inevitable defects which apparently can include (at least in CMOS sensors) entire rows or columns that are bad. This got me thinking - clearly these concealment patches are not completely undetectable in families of (multiple to many) images taken with the same exact camera... and for the most part the defects are born with the sensor and change little over time if at all. And with few exceptions they are random, and different for each sensor. Thus it ought to be possible to detect with reasonable probability that a particular image or (much easier) that a particular family of images was likely to have originated with a particular camera. A kind of digital fingerprint if you will... Cypherpunk relevance (marginal perhaps), but the ability to say that a particular image or set of images came from a particular camera COULD have legal consequences for those bent on activities someone thinks of as unfriendly to their interests... Of course the headers of jpegs from cameras (and maybe elsewhere) often contain serial numbers and other identifying information so to the first order this is irrelevant to average users, but interesting none the less. -- Dave Emery N1PRE, die(a)dieconsulting.com DIE Consulting, Weston, Mass 02493

Since 9/11, the lower echelons of the security apparatus know that if Something Bad happens, and they are shown to have discounted any hint or suspicion concerning any person even very peripherally involved, their ass is grass and their career goes in the toilet.

Thanks for reminding me. I'd been putting off ordering my CD set. OTGH, I'm noticing a fair number of self-described anarchists who say they'll vote Bush, but only because it will hasten the inevitable final breakdown. -- Roy M.

>John's an "anarchist" now! LMAO! This is a perfect example of media bias and manufacture of enemies. Collecting public material at one place *is* anarchism today. You may laugh but 74% (or whatever is the % who believes Saddam personally piloted all 9/11 planes) of americans will believe it. So Mr. Young is anarchist for all practical purposes and consequences. And you are all his associates.

So...does Mr Young want to describe the FBI non/encounter? (Perhaps he has but I've been out of town and the hotmail account barfed up most recent posts.) What I don't yet fully grasp is why they bother. I suppose there are the following, but I suspect there's one key thing in their minds: 1) Scope out potential sources of arrestability. 2) Intimidate into "straighten up and fly right" 3) Pre-BB or not so-BB-work: Readily available weapons, etc...in case of raid? 4) Just sniffing out the orietation/motivations...ie, raghead or non-raghead? Of the above I consider 3) Unlikely, 2) Not superlikely, 1) Fairly likely and 4) Most probable. -TD >From: "Trei, Peter" <ptrei(a)rsasecurity.com> >To: "Trei, Peter" <ptrei(a)rsasecurity.com>, "John Young" <jya(a)pipeline.com>, > <cypherpunks(a)minder.net> >Subject: RE: Another John Young Sighting >Date: Mon, 23 Aug 2004 16:21:28 -0400 > >After some hiccups, I got a copy to Riad S.

I caught the rerun. I have John's appearence as an mpg; 13 Mb at VCD qual, ~65 at DVD qual. I think <2 minutes of a 30 minute show counts as fair use. If someone can take that much as a mail attachment, or has an acessible ftp site, I'd be happy to send it. I'd prefer someone who can post it for others. It's funny, but not deep. Peter

Edward "Ted" Kennedy said Thursday that he was stopped and questioned at airports on the East Coast five times in March because his name appeared on the government's secret "no-fly" list. <SNIP> "That a clerical error could lend one of the most powerful people in Washington to the list -- it makes one wonder just how many others who are not terrorists are on the list," said Reggie Shuford, a senior ACLU counsel. "Someone of Sen. Kennedy's stature can simply call a friend to have his name removed, but a regular American citizen does not have that ability. He had to call three times himself." <SNIP> ----------------------Kaos-Keraunos-Kybernetos--------------------------- + ^ + :"Our enemies are innovative and resourceful, and so are we. /|\ \|/ :They never stop thinking about new ways to harm our country /\|/\ <--*-->:and our people, and neither do we." -G.
