Medical anonymity
by Clay Olbon II 17 Dec '03

17 Dec '03

It probably should no longer surprise me when the popular press is ignorant of anonymity, but of course it still does. There were several otherwise excellent articles in the Detroit News today (http://www.detnews.com/) about DNA research and inherited diseases (specifically breast cancer). The gist of one of the stories is that there are several reasons that deter people from being tested for genetic predispositions to disease, but that one of the primary ones is the fear of losing one's health insurance. Nowhere in the article was the possibility of anonymous testing mentioned. This is a severe oversight in my opinion. Clearly, being tested for a genetic disorder would not require disclosure of one's true name, and the testing could be paid for in cash (of course providing genetic material could eventually be indexed into a database to discover that true name, but I doubt we are there yet, at least I hope not!) The implication of most articles regarding this subject are that "there ought to be a law" prohibiting disclosure by medical practioners. Of course, most of us would probably agree that the proper approach is allowing non-disclosure by those tested. I don't know whether this is currently "legal", is there a legal requirement that medical practioners have "true names" before testing? Medical testing provides a unique opportunity to acquaint the public with the benefits of anonymity. Most americans can clearly see the payoff - not having your health insurance cancelled. Other anonymous transactions have somewhat less tangible benefits for the majority of americans (sorry to be so america-centric, maybe I should change the phrasing to citizen-units ;-) That's my minor rant for a Sunday AM. Now back to my x-mas shopping!

Published reports as done in the computer magazines are anecdotal evidence. They neither print their error bands on their stats, the raw results of their tests, or their complete test proceedures.

Even then it would have been very difficult. Still, one prefers to be careful. Rivest is said to be a clever fellow. One or two people at the NSA must know what they are doing. We wouldn't want to bet they aren't smart enough to invent something surprising. Perhaps we should define MD5-Cypherpunks. All interested parties submit sealed random values for the chaining variables and the t_i constants. The new constants are determined by opening the envelopes and XORing all the values. This probably isn't worth the trouble given MD5's known weaknesses, but it might be cool for other algorithms. Does it seem reasonable that this would make cryptanalysis more challenging? One could imagine that brute force attacks exist which are less efficient when the same setup cannot be used for every message. Or, that it is expensive to determine weaknesses for particular sets of constants. It would cause interoperability problems, but one could imagine some organizations would prefer to use their own version of standard algorithms for internal communications if it really did raise the cost of attack. The changes in software would be minimal. Incidentally, when weaknesses were discovered in MD5, did they depend on a particular set of constants, or were the weaknesses general? (I assume the latter, but I would like to know for sure.) Peter Hendrickson ph(a)netcom.com

What a great meeting!
by Lucky Green 17 Dec '03

17 Dec '03

I just returned from the monthly CP meeting. This month's meeting was hosted by PGP, Inc. thanks to the efforts of Dave del Torto, who is now with PGP. I would like to publicly thank Dave for making this meeting possible. It was the best CP meeting in a long time. I very much enjoyed Eric Blossom's demo of his voice encryption product. The sound quality is the best I ever heard in such a product. And it uses 3DES. The encryption and sound quality are much better than what you get from AT&T's STU-III. But nothing could have prepared me for the generous gift that PGP, Inc. made to each attendee: a four volume bound set of the *full* pre-alpha source to PGP 3.0, totaling almost 2,000 pages! Way to go, Dave. -- Lucky Green <mailto:shamrock@netcom.com> PGP encrypted mail preferred Make your mark in the history of mathematics.

I caught only part of a LONG (by network news standards) piece on crypto with PRZ, Jimmy SuperFed Kellstrom and Scott Charney. If CBS news is yet to air in your area, it is well worth your time to see, and perhaps record.

I know because I've been > there and spent quite a bit of time trying to get a rating. I think there are two issues here, Firefly and PICS. Confusing one with the other is a bad thing. PICS is simply one way of applying labels to content. Its sole reason for being was to head off the CDA. Now that the judicial route has been taken I see little likelyhood that PICS can succeed since either the supreme court will uphold the CDA and we have the Singapore scenario or the CDA gets booted out and the matter is over. If the US congress had wanted to do any good instead of making itself look good then the voluntary approach of PICS with the multiple rating schemes was the one most likely to work. I don't think that it would stop 16 year olds from seeing pornography but since children of that age are in most jurdisdictions permitted by law to engage in sex on their own account it seems a bit bizare to prohibit them from seeing pictures of sexual acts. The problem with Firefly is that its a good(ish) idea baddly implemented. The much vaunted "agent" technology uses only a very primitive nearest neighbour type match. There is no attempt to draw structural inferences from the material, such as abstractions. For example if I enjoy Dire Straights and Peter Gabriel then a shop assistant would peg me as a late 70s rock fan and point me towards the Fleetwood Mac and such. Firefly has 50% of the structure needed to produce interesting matches but lacks the ability to make inferences. At least if it is the same technology as Ringo, the previous generation. This shortcomming of Ringo means that it is very slow work training it. To get a useful measure it needs hundreds of data points. When I visited I was faced with page after page of US 90s chart bands which I've not heard of and have no interest in. Phill
