           London Transport Bombings



I was on vacation last weekend, and still haven't had a lot of time to read 
or write about the London Transport bombings. For now, I would just like to 
express my sympathy and condolences to those directly affected, and to the 
good people of London, England, Europe, and the world. Targeting innocents 
might be an effective tactic, but that doesn't make it any less craven and 
despicable.

I would also like to urge everyone not to get wrapped up in the particulars 
of the terrorist tactics. We need to resist the urge to react against the 
particulars of this particular terrorist plot, and to keep focused on the 
terrorists' goals. Spending billions to defend our trains and buses at the 
expense of other counterterrorist measures makes no sense. Terrorists are 
out to cause terror, and they don't care if they bomb trains, buses, 
shopping malls, theaters, stadiums, schools, markets, restaurants, discos, 
or any other collection of 100-plus people in a small space. There are 
simply too many targets to defend, and we need to think more intelligently 
than simply protecting the particular targets the terrorists attacked last 
week.

Smart counterterrorism focuses on the terrorists and their funding -- 
stopping plots regardless of their targets -- and emergency response that 
limits their damage.

I'll have more to say next month. But again, my sympathy goes out to those 
killed and injured, their family and friends, and everyone else in the 
world indirectly affected by these acts as they are endlessly replayed in 
the media.

  Terrorism Defense: A Failure of Imagination



The 9/11 Commission report talked about a "failure of imagination" before 
the 9/11 attacks:  "The most important failure was one of imagination. We 
do not believe leaders understood the gravity of the threat. The terrorist 
danger from Bin Ladin and al Qaeda was not a major topic for policy debate 
among the public, the media, or in the Congress. Indeed, it barely came up 
during the 2000 presidential campaign."

More generally, this term has been used to describe the U.S. government's 
response to the terrorist threat. We spend a lot of money defending against 
what they did last time, or against particular threats we imagine, but 
ignore the general threat or the root causes of terrorism.

With the London bombings, we're doing it again. I was going to write a long 
post about this, but Richard Forno already wrote a nice essay.

   CardSystems Exposes 40 Million Identities



The personal information of over 40 million people has been hacked. The 
hack occurred at CardSystems Solutions, a company that processes credit 
card transactions. The details are still unclear. The New York Times 
reports that "data from roughly 200,000 accounts from MasterCard, Visa and 
other card issuers are known to have been stolen in the breach," although 
40 million were vulnerable. The theft was an intentional malicious computer 
hacking activity: the first in all these recent personal-information 
breaches, I think. The rest were accidental -- backup tapes gone walkabout, 
for example -- or social engineering hacks. Someone was after this data, 
which implies that's more likely to result in fraud than those peripatetic 
backup tapes.

CardSystems says that they found the problem, while MasterCard maintains 
that they did; the New York Times agrees with MasterCard. Microsoft 
software may be to blame. And in a weird twist, CardSystems admitted they 
weren't supposed to keep the data in the first place.

 >From the New York Times:  "The official, John M. Perry, chief executive 
of CardSystems Solutions...said the data was in a file being stored for 
'research purposes' to determine why certain transactions had registered as 
unauthorized or uncompleted."

Yeah, right. Research = marketing, I'll bet.

This is exactly the sort of thing that Visa and MasterCard are trying very 
hard to prevent. They have imposed their own security requirements on 
companies -- merchants, processors, whoever -- that deal with credit card 
data. Visa has instituted a Cardholder Information Security Program (CISP). 
MasterCard calls its program Site Data Protection (SDP). These have been 
combined into a single joint security standard, PCI, which also involves 
Discover, American Express, JCB, and Diners Club to some degree.

PCI requirements encompass network security, password management, 
stored-data encryption, access control, monitoring, testing, policies, etc. 
And the credit-card companies are backing these requirements up with stiff 
penalties: cash fines of up to $100,000, increased transaction fees, and 
termination of the account. For a retailer that does most of its business 
via credit cards, this is an enormous incentive to comply.

These aren't laws, they're contractual business requirements. They're not 
imposed by government; the credit card companies are mandating them to 
protect their brands.

Every credit card company is terrified that people will reduce their credit 
card usage. They're worried that all of this press about stolen personal 
data, as well as actual identity theft and other types of credit card 
fraud, will scare shoppers off the Internet. They're worried about how 
their brands are perceived by the public. And they don't want some idiot 
company ruining their reputations by exposing 40 million cardholders to the 
risk of fraud. (Or, at least, by giving reporters the opportunity to write 
headlines like "CardSystems Solutions hands over 40M credit cards to hackers.")

So independent of any laws or government regulations, the credit card 
companies are forcing companies that process credit card data to increase 
their security. Companies have to comply with PCI or face serious consequences.

Was CardSystems in compliance? They should have been in compliance with 
Visa's CISP by 30 September 2004, and certainly they were in the highest 
service level. (PCI compliance wasn't required until 30 June 2005 -- about 
two weeks after the breach was announced.) The reality is more murky.

Also from the New York Times:

"After the disclosure of the security breach at CardSystems, varying 
accounts were offered about the company's compliance with card association 
standards.

"Jessica Antle, a MasterCard spokeswoman, said that CardSystems had never 
demonstrated compliance with MasterCard's standards. 'They were in 
violation of our rules,' she said.

"It is not clear whether or when MasterCard intervened with the company in 
the past to insure compliance, but MasterCard said Friday that it had now 
given CardSystems 'a limited amount of time' to do so.

"Asked about compliance with Visa's standards, a Visa spokeswoman, Rosetta 
Jones, said, 'This particular processor was not following Visa's security 
requirements when we found out there was a potential data compromise.'

"Earlier, Mr. Perry of CardSystems said his company had been audited in 
December 2003 by an unspecified independent assessor and had received a 
seal of approval from the Visa payment associations in June 2004."

All of this demonstrates some limitations of any certification system. One, 
companies can take advantage of interpersonal and intercompany politics to 
get themselves special treatment with respect to the policies. And two, all 
audits rely to a great extent on self-assessment and self-disclosure. If a 
company is willing to lie to an auditor, it's unlikely that it will get caught.

Unless they get really caught, like this incident.

Self-reporting only works if the punishment exceeds the crime. The reason 
people accurately declare what they bring into the country on their customs 
forms, for example, is because the penalties for lying are far more 
expensive than paying any duty owed.

If the credit card industry wants their PCI requirements taken seriously, 
they need to make an example out of CardSystems. They need to revoke 
whatever credit card processing license CardSystems has, to the maximum 
extent possible by whatever contracts they have in place. Only by making 
CardSystems a demonstration of what happens to someone who doesn't comply 
will everyone else realize that they had better comply.

(CardSystems should also face criminal prosecution, but that's unlikely in 
today's business-friendly political environment.)

I have great hopes for PCI. I like security solutions that involve 
contracts between companies more than I like government intervention. Often 
the latter is required, but the former is more effective. Here's PCI's 
chance to demonstrate their effectiveness.

               Noticing Data Misuse



Everyone seems to be looking at their databases for personal information 
leakages.  Here's one article:

"Tax liens, mortgage papers, deeds, and other real estate-related documents 
are publicly available in on-line databases run by registries of deeds 
across the state. The Globe found documents in free databases of all but 
three Massachusetts counties containing the names and Social Security 
numbers of Massachusetts residents....

"Although registers of deeds said that they are unaware of cases in which 
criminals used information from their databases maliciously, the 
information contained in the documents would be more than enough to steal 
an identity and open new lines of credit...."

Isn't that part of the problem, though? It's easy to say "we haven't seen 
any cases of fraud using our information," because there's rarely a way to 
tell where information comes from. The recent epidemic of public leaks 
comes from people noticing the leak process, not the effects of the leaks. 
So everyone thinks their data practices are good, because there have never 
been any documented abuses stemming from leaks of their data, and everyone 
is fooling themselves.

  Indian Call Center Sells Personal Information



There was yet another incident where a call center staffer was selling 
personal data. The data consisted of banking details of British customers, 
and was sold by people at an outsourced call center in India.

I predict a spate of essays warning us of the security risks of offshore 
outsourcing. That's stupid; this has almost nothing to do with offshoring. 
It's no different than the Lembo case, and that happened in the safe and 
secure United States.

There are security risks to outsourcing, and there are security risks to 
offshore outsourcing. But the risk illustrated in this story is the risk of 
malicious insiders, and that is mostly independent of outsourcing. Lousy 
wages, lack of ownership, a poor work environment, and so on can all 
increase the risk of malicious insiders, but that's true regardless of who 
owns the call center or in what currency the salary is paid in. Yes, it's 
harder to prosecute across national boundaries, but the deterrence here is 
more contractual than criminal.

(On the one hand, since the standard of living is lower in India, it's 
presumably cheaper to bribe employees.  But on the other hand, offshore 
employees, since they're well-paid by comparison to general salaries, have 
more incentive to keep their jobs.)

The problem here is people, not corporate or national boundaries.

            Write Down Your Password



Last month, Microsoft's Jesper Johansson made the news when he urged people 
to write down their passwords.  This is good advice, and I've been saying 
it for years.

Simply, people can no longer remember passwords good enough to reliably 
defend against dictionary attacks, and are much more secure if they choose 
a password too complicated to remember and then write it down.  We're all 
good at securing small pieces of paper.  I recommend that people write 
their valuable passwords down on a small piece of paper, and keep it with 
their other valuable small pieces of paper: in their wallet.  Obscure it 
somehow if you want added security: write "bank" instead of the URL of your 
bank, transpose some of the characters, leave off your userid.  This will 
give you a little bit of time if you lose your wallet and have to change 
your passwords.  But even if you don't do any of this, writing down your 
impossible-to-memorize password is more secure than making your password 
easy to memorize.

      The Adaptability of Iraqi Insurgents



This Newsweek article on the insurgents in Iraq includes an interesting 
paragraph on how they adapt to American military defenses.

"Counterinsurgency experts are alarmed by how fast the other side's tactics 
can evolve. A particularly worrisome case is the ongoing arms race over 
improvised explosive devices. The first IEDs were triggered by wires and 
batteries; insurgents waited on the roadside and detonated the primitive 
devices when Americans drove past. After a while, U.S. troops got good at 
spotting and killing the triggermen when bombs went off. That led the 
insurgents to replace their wires with radio signals. The Pentagon, at 
frantic speed and high cost, equipped its forces with jammers to block 
those signals, accomplishing the task this spring. The insurgents adapted 
swiftly by sending a continuous radio signal to the IED; when the signal 
stops or is jammed, the bomb explodes. The solution? Track the signal and 
make sure it continues. Problem: the signal is encrypted. Now the Americans 
are grappling with the task of cracking the encryption on the fly and 
mimicking it-so far, without success. Still, IED casualties have dropped, 
since U.S. troops can break the signal and trigger the device before a 
convoy passes. That's the good news. The bad news is what the new 
triggering system says about the insurgents' technical abilities."

The CIA is worried that Iraq is becoming a far more effective breeding 
ground for terrorists than Afghanistan ever was, because they get 
real-world experience with urban terrorist-style combat.

The Hymn Project exists to break the iTunes mp4 copy-protection scheme, so 
you can hear the music you bought on any machine you want.  Initially, the

figured out how to recover the keys cleanly. To get around this, they 
developed a program called FairKeys that impersonates iTunes and contacts 
the server. Since the iTunes client can still get your password, this 
works.  More security by inconvenience, and yet another illustration of the 
never-ending arms race between attacker and defender.

              Organized Retail Theft



There are two distinct shoplifting threats: petty shoplifting and Organized 
Retail Theft.  "ORT crime is separate and distinct from petty shoplifting 
in that it involves professional theft rings that move quickly from 
community to community and across state lines to steal large amounts of 
merchandise that is then repackaged and sold back into the marketplace. 
Petty shoplifting, as defined, is limited to items stolen for personal use 
or consumption."

Their list of 50 most shoplifted items consists of small, expensive things 
with long shelf life: over-the-counter drugs, mostly.

               SHA-1 Cryptanalysis



In February, I wrote about a group of Chinese researchers who broke the 
SHA-1 hash function. That posting was based on short notice from the 
researchers. Since then, many people have written me asking about the 
research and the actual paper, some questioning the validity of the 
research because of the lack of documentation.

The paper did exist; I saw a copy. They will present it at the Crypto 
conference in August. I believe they didn't post it because Crypto requires 
that submitted papers not be previously published, and they misunderstood 
that to mean that it couldn't be widely distributed in any way.

Now there's a copy of the paper on the Web. You can read "Finding

                  Security Skins



Much has been written about the insecurity of passwords. Aside from being 
guessable, people are regularly tricked into providing their passwords to 
rogue servers because they can't distinguish spoofed windows and webpages 
from legitimate ones.

There's a clever scheme by Rachna Dhamija and Doug Tygar at the University 
of California Berkeley that tries to deal with the problem. It's called 
"Dynamic Security Skins," and it's a pair of protocols that augment passwords.

First, the authors propose creating a trusted window in the browser 
dedicated to username and password entry. The user chooses a photographic 
image (or is assigned a random image), which is overlaid across the window 
and text entry boxes. If the window displays the user's personal image, it 
is safe for the user to enter his password.

Second, to prove its identity, the server generates a unique abstract image 
for each user and each transaction. This image is used to create a "skin" 
that automatically customizes the browser window or the user interface 
elements in the content of a webpage. The user's browser can independently 
reach the same image that it expects to receive from the server. To verify 
the server, the user only has to visually verify that the images match.

Not a perfect solution by any means -- much Internet fraud bypasses 
authentication altogether and this system is susceptible to 
man-in-the-middle attacks -- but two clever ideas that use visual cues to 
ensure security. You can also verify server authenticity by inspecting the 
SSL certificate, but no one does that. With this scheme, the user has to 
recognize only one image and remember one password, no matter how many 
servers he interacts with. In contrast, the recently announced Site Key 
(Bank of America's implementation of the Passmark scheme) requires users to 
save a different image with each server.

  Evaluating the Effectiveness of Security Countermeasures



Amidst all the emotional rhetoric about security, it's nice to see 
something well-reasoned. A New York Times op-ed by Nicholas 
Kristof  earlier this month looks at security as a trade-off, and makes a 
distinction between security countermeasures that reduce the threat and 
those that simply shift it.

I wrote about this in Beyond Fear:  "A burglar who sees evidence of an 
alarm system is more likely to go rob the house next door. As far as the 
local police station is concerned, this doesn't mitigate the risk at all. 
But for the homeowner, it mitigates the risk just fine."

The difference is the perspective of the defender.

Problems with perspectives show up in counterterrorism defenses all the 
time. Also from Beyond Fear:  "It's important not to lose sight of the 
forest for the trees. Countermeasures often focus on preventing particular 
terrorist acts against specific targets, but the scope of the assets that 
need to be protected encompasses all potential targets, and they all must 
be considered together. A terrorist's real target is morale, and he really 
doesn't care about one physical target versus another. We want to prevent 
terrorist acts everywhere, so countermeasures that simply move the threat 
around are of limited value. If, for example, we spend a lot of money 
defending our shopping malls, and bombings subsequently occur in crowded 
sports stadiums or movie theaters, we haven't really received any value 
from our countermeasures."

               Redefining Spyware



The problem with spyware is that it can be in the eye of the 
beholder.  There are companies that decry the general problem, but have 
their own software report back to a central server.

This kind of thing can result in a conflict of interest: "Spyware is 
spyware only if I don't have a corporate interest in it."  Here's the most 
recent example:  "Microsoft's Windows AntiSpyware application is no longer 
flagging adware products from Claria Corp. as a threat to PC users.  Less 
than a week after published reports of acquisition talks between Microsoft 
Corp. and the Redwood City, Calif.-based distributor of the controversial 
Gator ad-serving software, security researchers have discovered that 
Microsoft has quietly downgraded its Claria detections. "

If you're a user of AntiSpyware, you can fix this.  Claria's spyware is now 
flagged as "Ignore" by default, but you can still change the action to 
"Quarantine" or "Remove."  I recommend "Remove."  Actually, I recommend 
using another product.

               Talking to Strangers



In Beyond Fear I wrote: "Many children are taught never to talk to 
strangers, an extreme precaution with minimal security benefit."

In talks, I'm even more direct. I think "don't talk to strangers" is just 
about the worst possible advice you can give a child. Most people are 
friendly and helpful, and if a child is in distress, asking the help of a 
stranger is probably the best possible thing he can do.

This advice would have helped Brennan Hawkins, the 11-year-old boy who was 
lost in the Utah wilderness for four days last month.  He avoided people 
searching for him because he had been taught not to talk to strangers.

In a world where good guys are common and bad guys are rare, assuming a 
random person is a good guy is a smart security strategy. We need to help 
children develop their natural intuition about risk, and not give them 
overbroad rules.

Also in Beyond Fear, I wrote:

"As both individuals and a society, we can make choices about our security. 
We can choose more security or less security. We can choose greater 
impositions on our lives and freedoms, or fewer impositions. We can choose 
the types of risks and security solutions we're willing to tolerate and 
decide that others are unacceptable.

"As individuals, we can decide to buy a home alarm system to make ourselves 
more secure, or we can save the money because we don't consider the added 
security to be worth it. We can decide not to travel because we fear 
terrorism, or we can decide to see the world because the world is 
wonderful. We can fear strangers because they might be attackers, or we can 
talk to strangers because they might become friends."

Subject: Stupid People Buy Fake Concert Tickets

Your analysis includes the assumption that the system is actually used as 
you profess. In practice I have purchased and printed TicketMaster online 
tickets for a number of shows and NEVER has the venue actually scanned the 
tickets. Knowing that, people may expect that even a scalped ticket would 
get them in...all depends on the shows and the venue. Admittedly, the shows 
I am referencing are not necessarily big-name shows or at big-name venues, 
but the point remains.

Along the same lines, I keep wondering how hard it would be for somebody to 
write a virus that checked mailboxes on POP servers for e-mails including 
"ticketmaster" in the FROM address with attached PDFs and sending the PDFs 
to a central location.

The above is especially useful if a scalper takes the tickets, sells one 
copy and just tells the individuals to get there early (i.e., before the 
valid ticket holders). Then the VALID ticket holders get denied access...or 
come to find innocent scam-victims sitting in their seats.

Subject: Forget X-ray strip-searches

Using soft X-rays to examine people for weapons is just the foot in the 
door. What happens when police cars are equipped with it, scanning people 
on the street for proscribed items? Will aluminized clothing become vogue, 
just for the privacy, or will that become proscribed as well?

Worse is terahertz imaging radar. Like soft X-ray backscatter, it can see 
through clothing. Unlike it, it can also see through walls. I can imagine 
police vans cruising residential streets, performing searches of homes 
without having to enter the home. They could claim no search warrant is 
needed because they do not even enter the property, let alone the 
home.  Combined with image recognition computers, a scan-search of a home 
could be done very quickly.

The questions become:

1. will the police be permitted to immediately break in and arrest people 
found this way possessing contraband, much like police observing a crime 
through an open window?

2. Will soft X-ray and terahertz imaging radar be allowed to be used to 
perform scan-searches of people on the street, especially without their 
knowledge or permission?

3. Will the courts allow such evidence in court, or as grounds for a legal 
search warrant?

4. Will passive countermeasures to soft X-ray backscatter and terahertz 
imaging radar be proscribed for public use, much like bullet-proof vests 
are in many areas? (Aluminized clothing and drapes on windows, aluminum 
sheathing on walls and ceiling, metalized or virtual windows).

With the anti-privacy policies of the current administration, I can see an 
era where our fourth amendment rights may become meaningless.

Back in the 1960s and 1970s, there was a public outcry about governmental 
computer data bases on individuals, and Congress virtually outlawed 
them.  Today, they are as common as cockroaches in a slum. This technology 
will have the same creep into our daily lives.

 > The healthcare industry has been opposed to HIPAA from the

Many physicians such as myself are opposed to the protected information 
portions of HIPAA (which is fairly comprehensive legislation dealing with a 
number of topics), not because it puts constraints on business, but because 
it simply is not the federal government's business to regulate the flow of 
medical information.

The practice of medicine and the protection of patients has always been 
strictly in the domain of the states and the privacy regulations of HIPAA 
are no more than an attempt by Washington to continue to creep and expand 
its authority and influence to cover every aspect of government of our nation.

Beyond the fact that the federal government has no business regulating the 
practice of medicine, HIPAA is simply... stupid. The regulations are 
ridiculously stringent and absurd for no justifiable reason. For example, 
HIPAA purports (I believe HIPAA to be unconstitutional and hence invalid -- 
thus the use of the word "purports") to proscribe a physician giving 
information regarding a patient to third parties except with the patient's 
express consent or in certain circumstances.

This means that a physician receiving a phone call, for example from a 
patient's relative asking for information about the patient, cannot provide 
that information unless the patient has previously given their express consent.

This is (1) simply stupid. The physician should use their judgment about 
the medical situation and its character/seriousness, and whatever knowledge 
they have of the patient and their family, and make a determination 
regarding whether or not it is appropriate to talk to that family member. 
And (2) even if not stupid, simply not the federal government's business. 
This kind of stuff is regulated on the state level.

Subject: Re: Risks of Pointy Knives

As a woodworker, engineer, and connoisseur of good knives and sharp things 
in general, I can identify some of the reasons for the continued existence 
of pointy ends on longer blades, in the order of what I believe to be 
greatest to least effect.

1. Consumer expectations:  Same reason most vacuum cleaners are 
intentionally much louder than necessary. People subconsciously equate the 
effectiveness of the vacuum with its noise level, and if you give the 
buying public a pencil and ask them to draw a knife, they will give it a 
pointy end. Whether this is a bow to knives' potential use as a weapon, or 
a demonstration of the inertia of public perception is a matter for a 
different letter.

2. Mechanics of balance:  Most users are comfortable with a blade that has 
a balance point (more accurately, the center of the moment of inertia, for 
fellow nerds) close to the transition from handle to blade. If a blade is 
longer than the handle it is attached to, the simplest means of maintaining 
the proper balance it to taper the blade. If a blade tapers in thickness, 
intuitive design dictates that it should also taper in width, maintaining a 
relatively constant aspect ratio in cross section. This results in a point.

3. Mechanics of curved cuts:  The minimum radius of a concave curved cut 
that a knife can make is limited by the width of the blade. In order to 
maximize utility, some portion of a blade should be very narrow if curved 
cuts are intended. Mechanics of materials dictates that the narrow portion 
should be at the end of a tapering blade; in other words, it should come to 
a point.

4. Mechanics of cutting in swung blades:  Blades that are intended to be 
used dynamically, or swung, such as a machete, can actually require a point 
for best effect. As you know, a slicing cut is most often more effective 
than simply forcing a blade into a material perpendicular to the edge. 
There are two reasons for this which I won't go into here; suffice to say 
that in order to achieve this slicing motion in a swung blade, the cutting 
edge is set at an angle to the direction of travel. This can result in a 
curved blade, as in the scimitar, or more commonly, a long blade that 
tapers to a point. This doesn't apply to kitchen knives, as most aren't 
swung, and cleavers are intended to cut by wedging, as slicing is 
ineffective on rigid materials such as bone.

I have always carried knives when I'm out and about. I also usually carry 
some form of pliers, a flashlight, a pen; in one word, tools. My primary 
knife is a tanto-blade 3.95" lockblade clipped into my pocket, and 
sometimes it is visible. From time to time I am questioned on why I'm 
carrying a weapon, and have to explain the following:

I have never, and hopefully never will use a knife in self-defense and 
certainly not in anger for the simple fact that a knife is only an 
effective weapon in a very few situations where you have an element of 
surprise and intend to permanently disable or more likely kill your 
opponent outright. I don't put myself in those type of situations.

The situation I am more likely to encounter is a belligerent attack borne 
out of anger or intent of robbery. In this situation, I don't want to kill, 
but only temporarily disable or merely slow down my opponent enough to get 
away, a very poor task for a knife. Deep puncture wounds from stabbing or 
lacerations from slicing do not disable unless very carefully placed, 
leaving you with an enraged attacker, a slippery sharp blade in your hand, 
and very likely legal charges of assault with a deadly weapon.

I do not think that availability of pointy knives should be placed in the 
same security category as handguns for two reasons.  One, long pointy 
knives have more legitimate uses than defense or attack.  And two, pointy 
knives, or any knife, derives its effectiveness from the skill and strength 
of the user. Handguns derive their effectiveness from stored chemical 
energy and require almost no skill to create deadly force.

At the end of the day, security risk lies not in the tools a person uses to 
attack others; it lies in the intent of the mind wielding the tools. 
Deprived of one tool, a person with intent will choose another. 
Mathematically, you can consider this unbounded, iteration without end; 
therefore, we would be better from an efficiency standpoint to attempt to 
limit the causes of intent and vulnerability to attack rather than the 
tools of attack.

Subject: Re: Risks of Pointy Knives

Why are long knives pointy?  Mechanical engineering, cost efficiency, and 
tradition.

European long knives are traditionally made by a stock removal method -- 
the cutting edge is created by grinding away metal to reach the shape of 
the blade.  Knives are pointy at the end because it's easier to reach that 
shape when you're grinding the edge into a curve.

There's also a cost implication, because although the point of a long knife 
is rarely used to stab anything in a cooking context, the cutting surface 
is used all the way to the end of the knife, which naturally leads to a 
point.  If you want to make a knife that's missing the last half inch or so 
of cutting edge, then you really need to make the whole knife a half inch 
longer to achieve the same utility.  The stock removal approach means you 
have to start with a bigger piece of steel.

The tradition aspect is simple.  Knives of any kind are evolved from 
designs that are thousands of years old, and people's impressions of what a 
knife should look like and how it should be used are hard to 
change.  There's no universally agreed point at which a knife becomes too 
long to be used for stabbing things as well as cutting them.  When most of 
the well-known, high quality mass-produced chefs knives in the world are 
made in the same handful of German towns they've been made in for the past 
three hundred years, and people are still buying them, there's little 
incentive to mess with the formula.

Subject: Re: Public Disclosure of Personal Data Loss

Bruce, your comments on Data Loss were spot on. Yes, it has been going on 
for years and yes, the sensitivity of the public to such losses will decline.

You closed with, "Public disclosure is good. But it's not enough." The 
answer to your implied question about how we solve this mess currently lies 
in regulatory oversight. Most of the companies that have suffered public 
disclosures of personal data loss are financial service organizations 
governed by regulators. Behind the scenes, the regulators are making it 
very clear that they are dissatisfied with the current levels of controls 
over personally identifiable information and expect significant changes to 
be made. The regulated companies are responding, because they have to.

Those companies that have suffered losses, but which are not regulated 
(e.g., ChoicePoint), clearly do not want such incidents to provide a reason 
for Congress to add them to the list of regulated entities. This provides a 
clear incentive for the non-regulated companies to make changes.

The other driving force is outsourcing. No country supports the outsourcing 
of jobs to another country and will use any excuse to prevent or limit the 
loss of jobs. One argument that is receiving a great deal of attention in 
Congress is that the offshore outsourcing companies have poor security and 
present an increased risk of data loss. Whether the argument is based in 
fact or not, it attracts significant public support. Any company that is 
heavily dependent on offshore outsourcing of personal information 
processing understands the potential risk that the government may place 
significant limitations on moving data offshore and realizes that it must 
take steps to ensure the public that their data is protected. In most 
cases, if the company devises ways to protect data as it moves offshore, it 
will be able to use the same processes domestically.

I'm not worried about whether U.S. companies get the message. I'm more 
worried about whether they will be able to devise solutions quickly enough 
that effectively and efficiently address the issue. Because if they are 
unsuccessful, we should we all go out and buy stock in Brinks.

Subject: Re: REAL ID

In response to Petri Aukia on IDs: There is a subtle difference you have 
not alluded to with regards to the European and American driver's licenses 
and their privacy implications.

The Finnish and French (most likely all other EU driver's licenses as well) 
do not have the home address of the driver.  They serve to document your 
existence, name, photo, signature, Social Security number, and the types of 
vehicles you are allowed to drive. Pictograms and standardized numbers and 
locations of datum are used so that a patrol officer can read a license 
from any EU country.

Each country has a mechanism to map from the Social Security number or the 
local equivalent to the current home address of the driver, but this is 
available only to the government and the companies you have given the right 
to know of your address (magazines, newspapers, and the like).

UK driving licenses show the holder's home address -- this is item 8 in the 
EU model license. This item is optional but appears on many photo licenses: 
e.g., this document about Spain.

Subject: Re: REAL ID

In the "Comments from Readers" section, Julien Maisonneuve said:  "In 
addition to your mention of European legal frameworks protecting data 
(which are not as complete and as prevalent across the union as one may 
wish), the very notion of identity theft is almost unknown in Europe. There 
are many causes, many linked to the limited benefits you can draw from 
'identity' by itself. This is including the absence of credit rating as it 
exists in the U.S., and different procedures to open bank accounts and get 
access to their resources."

There are other side-effects to this issue.  For one, knowing someone's 
bank account number is enough to be able to send them money, but not 
withdraw it.  Many businesses will print their bank account numbers on 
their letterhead, and some people will put their bank account numbers on 
their business cards.  There's no risk of having this information "stolen," 
because the banks don't allow you to withdraw money by knowing only the 
bank account number, and this makes it much easier to transfer money to 
someone electronically. This is a large part of the reason why no one uses 
checks anymore in Europe -- it's faster and easier to transfer the money 
electronically.

On the other hand, trying to set up electronic payment to U.S. accounts is 
a pain-in-the-ass.  I've tried to do it through my bank.  If they already 
have a record of the organization in question, it may only take two or 
three months to set up electronic billing and payment. It's not nearly so 
painful to do that in Europe.

Many European banks will create their own customized software to do all 
electronic banking, and this software will not only run on Windows but also 
on Macintosh and Linux.  Just about everything you can do by going to an 
ATM or visiting a branch in person can be done with this software, either 
in offline mode or in the online module.

There's another side-effect -- European banks and money lending 
institutions don't validate credit cards online.  They have to go through a 
manual process which takes hours to days to process, frequently involving 
manual intervention and the use of fax machines. This makes it very painful 
to do online shopping when the merchant requires online validation.  This 
makes it impossible to use any online storefront where online validation is 
the only choice available.

Even though they're Visa cards, and they have the Visa logo and hologram on 
them, they're not recognized as Visa cards because the first few digits of 
the card indicate that they are not issued to a U.S. banking 
institution.  If you rent cars from Avis, just tell them that the renter's 
address is overseas, and you can rent a vehicle on a check card, which is 
something that they don't normally allow.
