Some­one acci­den­tally sent em a link yes­ter­day to a secu­rity doc­u­ment that I was meant to read. I read the doc­u­ment (located here) and later dis­cov­ered he sent me the wrong link. Over all the paper is well writ­ten and has some strong the­ory behind it. I did have some con­cerns over this paper which I can address here.

Orig­i­nally I sent this back to the per­son that for­warded the wrong link to me:

“…You had a line that said “…photo ID cards offer the ter­ror­ist all new weak points for exploita­tion” did you use the word ter­ror­ist (since the paper didn’t seem to be about ter­ror­ism (which then it would be for­given in my view­point) because of the heart strings you felt it would tug at? Wouldn’t a bet­ter line to keep the doc­u­ment a bit more polit­i­cally neu­tral been some thing in the line of “photo ID cards offer pos­si­ble weak points for exploita­tion” or using the term fraud­sters like you do later in teh paper? I don’t like the term ter­ror­ist since it has con­no­ta­tions that have widely been twisted since 9/11 and the­o­ret­i­cally under some inter­pre­ta­tions of the PATRIOT act writ­ing this paper and exam­in­ing pos­si­ble weak­nesses and pub­lish­ing it could be a bor­der­line activ­i­tiy (I don’t believe that but strict inter­pre­ta­tion of the law could be taken as such).

Machine read­able weak­nesses could greatly be strength­ened by not rely­ing on a local com­puter but going to a cen­tral data­base while bring up the pic­ture on the screen like advanced doc­u­ments lead­ing into a two fac­tor authen­ti­ca­tion of machine then per­son ver­i­fi­ca­tion instead of the other way around of a casual glance — this way the authen­ti­ca­tor looks at it twice. I don’t like the idea of a cen­tral­ized author­ity and I’m against a national ID card for this rea­son — the pri­vacy con­cerns are immense. The sim­plest way would be when the card is print­ing place an MD5 hash that would need ned to match one printed holo­graph­i­cally on the front of the ID. This way edu­ca­tion would teach us (ver­i­fiers in gen­eral) that to ver­ify the ID — we scan it and then type in the pin that should match against the MD5 hash on the mag­netic strip. This allows us infint­tely more secu­rity then we have now with­out the pri­vacy loss impli­ca­tions of a cen­tral­ized authority.

Doc­u­ment fraud is always going to con­tinue as long as believe in the pri­vacy and rights of the indi­vid­ual. Doc­u­ment ver­i­fi­ca­tion does not nec. make our gov­ern­ment more secure. While some of the 9/11 ter­ror­ist had expired Visas — other had per­fectly valid non forged ones. If we track back his­tory to the last major ter­ror­ist attack before that Okla­homa City bomb­ing — that was done by an Amer­i­can with which I sup­pose had valid accu­rate documents. …”

As you can see by the ver­biage I used and the the fact that I didn’t pay extreme atten­tion at first I had mis­tak­enly thought the per­son that sent the link was the author. He was not and told me he couldn’t speak to the points con­tained within the paper. Fair enough.

I stated most of my points in my above email excerpt, how­ever one thing started nag­ging at me later (the same nag­ging that urged me to write this post. The author fails to take into con­sid­er­a­tion (or glazes over the fact in his paper) the inher­ent inse­cu­rity dur­ing the migra­tion period. While bor­der guards, guards at fed­eral gov­ern­ment facil­i­ties, and TSA rep­re­sen­ta­tives can be well trained ramp­ing up to launch of new iden­ti­fi­ca­tion, the pop­u­lace at large would nto have the same training.

Because the pop­u­la­tion at large would be vaguely aware of a new sys­tem but not sure the details of what to look for this opens up a win­dow of oppor­tu­nity for larger fraud to hap­pen then what dic­tates under the cur­rent sys­tem. I remem­ber busi­nesses hav­ing issues accept­ing the 20.00 bill when it was redesigned since many peo­ple thought it felt like play money and looked phoney. While they usu­ally (reluc­tantly) accepted it, I’m sure there was a good oppor­tu­nity for coun­ter­feit­ers dur­ing the weeks/months that followed.

Now if you notice above I men­tioned fed­eral agents, local police are nor­mally no bet­ter at detect­ing these things. If they called it in they may get con­fir­ma­tion, but some police depart­ments are lax and don’t fol­low a uni­fied pro­ce­dure. For an exam­ple of this idiocy please track down Steve Wozniak’s sto­ries about hav­ing issues with the police say­ing his 2.00 bills were phoney when a store man­ager who didn’t believe 2.00 bills existed asked the offi­cer that came into the store.

I’m not say­ing we should stay the course dur­ing all of this and some states should have a stronger anti tam­per­ing mech­a­nism. The realID issue try­ing to get into fruition is one attempt at the fed­eral level to do this. I don’t believe in the realID sys­tem since it erodes our per­sonal lib­er­ties so I don’t think there should ever be a cen­tral author­ity. I could go on and rail about the realID sys­tem — but you should search “ron paul realID” and here that man’s thoughts on the issue.

Finally the cost of this reim­ple­men­ta­tion of iden­ti­fi­ca­tion papers. This is ome­thing com­pletely not absent in the doc­u­ment. If you look at the num­bers imple­ment­ing the realID sys­tem you can see the absolute cost that this will cost you for very lit­tle secu­rity in return.

  • That's fine I ran across it and felt a need to just comment on it. It's nothing personal in the fact of what I pointed out.


    If anything if you were to revisit and take this paper to the next step in the future just giving you or anyone else following in this direction another point of view on the subject.



    Though I still believe in the MD5 hash personally since this could give a degree of larger authenticity on machine readers that would not have a picture display to compare the person to a photo on file.

    Hi! I finally got around to reading your comments on my SDT whitepaper. I have to admit, I haven't looked at it for some time now...it was written in 2003/2004.


    Addressing your concerns in order...



    a.) Frankly, I didn't remember using the word "terrorist" in that second paragraph. I'm not crazy about its use now either, but perhaps it seemed less severe/more relevant in 2003.



    b.) As far as I can tell, your proposal of having a MD5 hash is simply to show that the machine readable element is valid. That seems like a lot of work for something that doesn't achieve much.



    c.) I guess I did glance over migration period problems. (I would have sworn I mentioned something about it--for instance, once a person knows what a new $100 bill looks like, they might accept them, but they will not necessarily know what they should be looking for in order to know the document is good.)
