Declan McCullagh has compiled responses from AOL, Microsoft, Yahoo and Google on the following questions (two of which are nearly verbatim from my previous query, uncredited):
So we’ve been working on a survey of search engines, and what data they keep and don’t keep. We asked Google, MSN, AOL, and Yahoo the same questions:
- What information do you record about searches? Do you store IP addresses linked to search terms and types of searches (image vs. Web)?
- Given a list of search terms, can you produce a list of people who searched for that term, identified by IP address and/or cookie value?
- Have you ever been asked by an attorney in a civil suit to produce such a list of people? A prosecutor in a criminal case?
- Given an IP address or cookie value, can you produce a list of the terms searched by the user of that IP address or cookie value?
- Have you ever been asked by an attorney in a civil suit to produce such a list of search terms? A prosecutor in a criminal case?
- Do you ever purge these data, or set an expiration date of for instance 2 years or 5 years?
- Do you ever anticipate offering search engine users a way to delete that data?
