PrivacyFinder.org: Search, but with Privacy
The level of privacy offered by search engines is generally woeful. Last year, the three big players (Google, Yahoo! and MSN) made some improvements by limiting the duration for full retention of logs about who has searched and what they've searched for. That means that after a year or two, it would be harder — though probably not impossible — for the major search engines and their advertising partners to reconstruct a complete history of your searches.
Ask.com went further with their AskEraser feature, which allows users to have their logs deleted and to opt-out of being tracked (Ask.com could have done better by finding a way for opt-out to be available without a cookie).
Despite these improvements, the average Internet user still has very little privacy for their search history. We have documented the measures you can take to protect yourself, but they aren't all that simple.
PrivacyFinder seems to be making productive use of P3P, an old privacy standard that has, in many other respects, fallen short of expectations. If you run a search on the site, you can quickly see when one result matches your standards and others don't.
Privacyfinder's logging policy is amongst the best in the industry (Ixquick is also first-rate). Privacyfinder only keeps search records for a week, unless the user explicitly opts in to being tracked. Because the CMU Laboratory wants to do research on the use of search engines, it's offering prizes for people who are willing to be tracked for research purposes. That's the way we like to see it done.
Meanwhile, several other developments are in the works. New York State legislators have been talking about taking parts of the search privacy problem into their own hands. There are rumors of new startups planning to enter the "privacy search" market. And EFF is working on a scorecard for systematically evaluating the effectiveness of various privacy measures at search engines. Stay tuned to Deeplinks for future developments!
