Telling Google and others to
do less evil
By: Scott Bradner
The search engine companies Google, Yahoo and others are in
the data gathering business. The
fact that they offer you and me the service of locating things on the Internet
is a means to an end, and that end is data about what you & I do on
line. They are like the folks that
hoard string - the more string they gather the better they feel even if there
is little of no actual use for most of what they gather.
Left to their own devices the search engine companies would
keep the data they collect about you forever but they are slowly waking up to
the fact that the Orwellian aspects of their business was beginning to get to
people. (See Orwell did not guess the worse half of it -
http://www.networkworld.com/columnists/2006/022706bradner.html) Recently Google decided to reduce the
time it kept data about your searches to 18 months, an improvement but not a
cure for the problem. (See

Europe feels differently about privacy than the US
does. In the US there are almost
no controls on the information companies collect about you. There are a few
controls on what data government can collect but it looks like the government
can get around the restrictions by buying access to the same date from the
private sector. In Europe they
have the quaint idea that people have a right to some level of privacy and they
enforce it in law. The best that
the US government is willing to do is to establish voluntary guidelines.
The EU has now fired a warning shot across the bows of the
search engine companies. A draft
report (http://ec.europa.eu/justice_home/fsj/privacy/docs/wpdocs/2008/wp148_en.pdf)
on the relationship between search engine business models and European privacy
laws has found plenty to worry about.
The report concludes that search engine companies have not shown that
they actually need to retain info collected about us for more than 6
months. The search engine
companies put forth a number of reasons that they want to keep the data longer
than that but the report (in Section 5.2) effectively demolishes the
reasons. For what it's worth, I
find it very hard to imagine how data older than some small number of months (6
sounds fine) can contribute meaningfully to predicting what I'm interested in
so that I can be shown ads that might attract my attention (which, after all,
is the reason to collect the data in the first place).
Google posted a reaction to the EU draft report (http://googlepublicpolicy.blogspot.com/2008/04/european-commissions-data-protection.html)
in which they repeated some of the arguments that the draft report, in my opinion,
properly dismissed.
The draft report also concluded
that IP addresses are personal info because they can help identify a
person. The Google response
referred to a previous posting on the topic
(http://googlepublicpolicy.blogspot.com/2008/02/are-ip-addresses-personal.html). But this posting, given the best
possible spin, is deeply misleading.
It is patently absurd to ignore the vary large number of IP addresses
that are not dynamic and to ignore the fact that even dynamic addresses can be
stable for months at a time (as mine was when I had cable-based Internet
service. There is not question in
any reasonable person's mind that very many IP addresses do identify a person. It is just this kind of clever but
purposefully misleading "information posting" that has destroyed the
creditability of the search engine companies when it comes to privacy related
topics.
As a final note, the EU draft
report also requires that search engines include a link to their privacy
policies on their home page and the search results. Such links are also required under California law (http://info.sen.ca.gov/pub/03-04/bill/asm/ab_0051-0100/ab_68_bill_20031012_chaptered.html). Yahoo complies with this requirement -
Google does not. Google does have
a privacy policy (http://www.google.com/privacy) and it's clear and too long.
But maybe hiding the policy is just another indication on what Google actually
thinks about privacy.
disclaimer: Harvard is required by law to protect the
privacy of its students and has not offered an opinion that this is not a good
idea, in any case the above review is my own.
