[comp.org.eff.talk] Philosophic Grounds of Privacy

wayner@hermod.cs.cornell.edu (Peter Wayner) (11/30/90)

I was re-reading H.F Saint's book _The Adventures of An Invisible Man_
which I heartily recommend to everyone in this newsgroup. Not only is
it filled with anti-government sentiment, but the author has a fine
wit. It was on the Best Sellers list for a bit.

The hero of the story becomes invisible by accident and at one point
he is at home when his secretary comes to pick up and drop off papers.
He hides by not announcing his presence and is scandalized to discover
that she procedes to search his room, look through his drawers, scan
his pictures, read his checkbook register and thousands of naughty 
deeds. He then launches into a solilioquoy (sp) that was most 
insightful. I will try to bring in the book to post a quote or two
tomorrow.

He essentially notes that privacy is really a social convention, not
something that Knowledge Theorists from Distributed Computing could
debate about. It is something in the way that people hide what they
know and are considerate, not something that can be modeled with set
theory. Most people quickly learn many details about all of the people
around them in a small amount of time. People can't hide that much and
there is just too much redundant information. 

Here's a hypothetical, social question. Deaths are a public matter--
not just in the same way that drunk driving convictions are, but in
more public sense. Newspapers run obituaries. Even so, you would not
mention to the cute girl you're chatting with, "So I hear your
Grandfather died back in 1985." This is a private matter. You 
also wouldn't mention, "So have you dried out since the DWI conviction
in 85?" The data's certainly public, but it's not polite.

So privacy is not a matter of forbidden information-- it is set of
social rules of tact that govern when it is polite to mention a topic.
This is the danger of the proposed database laws. They propose to set
up a class of forbidden facts about the world (which is a very scary
thought) and in most cases these facts can all be infered from public
sources. 

Just my usual two cents...
