On farming data shadows and other aluminium sleakness

Schneier on Security has an interesting bit on identity farming today. The idea essentially runs that one can incubate rock solid fake identities if they have 25 years during which to fabricate the birth of children, open bank accounts in their names, fill out the relevant paper work to have them home schooled, and otherwise scatter little bread crumbs here and there (apparently this is also a premise common in Highlander fan faction as a plot technique through which the immortals continue to stay integrated in human society). It is through these techniques that one creates, as Schneier nicely phrases it, a data shadow for the fictitious identity. This all could work, right, because it is the data shadow itself that is the salient aspect of one’s existence as a citizen-consumer and not really their corporeal person as such.

As a good case in point – one that also reveals the absurdity of the US’s paper tiger homeland security initiatives — a Quebec business man who had his identity stolen, consequentially winding up on a US terror watch list, was ultimately able to circumvent the travails of security check point purgatory by changing his name from Mario Labbé to François Mario Labbé . It seems its created a bit of a fresh start for him:  F. Mario Labbé can now pass through airport security unaccosted because of a vulnerability in, what we can perhaps refer to in a bit of biblical sounding legalese. the Several Databases.

It seems that this idea of a data shadow can be potentially quite powerful. It certainly has the ring of one of those buzz phrases that, like a sleak aluminum frame, can house either a powerbook or a fighter jet. Now what is wanting is for the notion to get caught in an updraft and to be transformed into the cynosure of public attention. At least, that would be nice.

Tall tales emerging from the shadows

Wow is this real? Or some sort of misinformation about US military technologies? Perhaps being spread in some attempt to reflect the total fear of terrorism that is nurtured within the US as a tool to demoralize those communities abroad that the US considers its enemies.

By analyzing the movements of human shadows in aerial and satellite footage, JPL engineer Adrian Stoica says, it should be possible to identify people from the way they walk - a technique called gait analysis, whose power lies in the fact that a person’s walking style is very hard to disguise.

It would be rather challenging to do, but quite interesting to see how stories like this propagate on the ground in places like Afganistan. That portion of the blogosphere that concerns itself with technoscience and national security have certainly been abuzz with this story, and there has been quite solid propagation of it. But at what point, if really ever, do these types of stories jump the fence, as it were, and enter the rumor mill of the third world? Do the US intelligence services study this sort of thing?

The implications of this are rather wild, in any event. On the one hand, it is another expression of the contemporary’s interest in reducing phenomena to a statistical trace. You are an aggregation of variables that correlate only in your instance. You went to that coffee shop today because there was an 80% chance of it.

Maybe terrorists will start wearing big puffy suits to obscure their shadows. Actually it sounds like a great market opportunity, selling surplus Willie Wonka and the Chocolate Factory costumes to terrorists…
