Subject: Summer Doldrums

Greetings.  We've now entered the "summer doldrums" period for
Internet Digests, where submissions and volume tend to drop
to minimums for the year.  So, this is a good time to submit
your own privacy concerns, concepts, horror stories, or other
relevant materials.  Remember, privacy is *you*.

   First, I believe that the tapping capability of Clipper/Capstone
   will prevent its ever replacing STU-IIIs and other complex
   algoritms for dedicated point-point connections that require
   absolute privacy.

Undeniably.  The question is who will be able to using STU-IIIs
without causing themselves potential problems.  The answer is "the
government, and no one else."

   Legislation from the government banning "any
   other cryptography" would be impossible to enforce and akin to
   trying to stuff knowlege back into Pandora's box. It is just not
   going to be happen and the government is intelligent enough not to
   take on a losing battle that could just flood the legal system (and
   there would be pleanty of floodees).

Since when has a law being impossible to enfoce prevented the
government from enacting it?  Consider: speed limits, drug use,
Prohibition.  Each of these *is* (was) a losing battle, and each *is*
flooding (did flood) the legal system.  And yet the governemnt
continues to stand behind impossible laws.  Why?

The NSA is not stupid.  They *know* they will be unable to prevent
dedicated people from using strong cryptography.  So why bother
mandating Clipper?  Because then anyone using strong cryto will be
labelling themself as a criminal, giving law enforcement authority to
arrest them (or just seize their assets) should the desire ever arise.

False. There would not be a flood. What would happen, if the govt made
non-Capstone encryption illegal, is that it would be considered prima-facie
evidence of criminal conspiracy (since only a criminal would want his
comm secure against monitoring by law-enforcement agents, right? Sure).

What would then happen is: if the govt wants to monitor you, and you use
non-Capstone, then they nail you. Make the penalties heavy enough, and
they don't really need to prove any of the charges they wanted to
monitor you for. After a few well-publicized cases, not too many people
will use non-Capstone encryption.

Subject: Questions for the Privacy Forum

An organization is planning to use the last four digits of employees
Social Security Numbers as part of a scheme for assigning computer
passwords.  I am not asking about the security aspects of this, but am
wondering about the privacy implications.  Is there anything particular
that needs to be considered about the last four digits as apposed to
four other digits?  Is this an acceptable use of (part of) social
security numbers?  Would it matter if the last nine digits (all of) or
the last one digit were used?  What precedents exist for allowing or
prohibiting such use?  What precedent is set by this proposed use?

I look forward to reading how readers would react if they faced such a
proposal.

Subject: Re: USPS NCOA request results

I can personally attest to the popularity of the USPS change of
address database.

Having moved twice in the past two years (first from New Jersey to a
rented house in San Diego, and again a year later within San Diego
when I bought a house), I had a chance to try out a trick suggested by
a local friend. Whenever I gave my new mailing address to someone, I
added a unique, bogus "apartment number" to keep track of how far that
particular copy of my address propagated.

It was hardly worth the effort. The *vast* majority of junk mail I
began to receive at each new address came with "#P", the code I had
added to the USPS change-of-address form. It even appears on my
address in the ham radio ARRL Repeater Directory listing for members
of the ARRL Future Systems Committee, of which I am a member. The
information you put on those harmless-looking little cards goes
*everywhere*.

And since I bought a house last August, another major source of junk
mail without a code has appeared that clearly uses the public real
estate records at the county clerk's office. It seems to go in cycles.
First were all the solicitations from burglar alarm, carpet and
drapery companies. Then it was "let us help you file your homestead
exemption". Now it's mortgage insurance and mortgage refinancing.

The moral is clear: if you want to disappear, don't file a change of
address form with the USPS, and don't buy a house. :-)

Subject: USPS NCOA request results

I, like Steve Peterson, received a thick bundle of dead trees from the USPS
asserting that any and all of the companies listed (several thousand names)
might have received my change-of-address.

Interestingly, the USPS also claims that only those companies that "already
had my address" could have gotten the new one.  I don't see how they could
assert this unless they're denying that they ever sold the list of
people-who-changed-addresses.

Just another data point...
