Microsoft Bing to Forget Your IP After 6 Months
Microsoft is cutting the length of time it retains Bing user data to just six months.
Microsoft today announced that it is cutting the number of months it retains "the entire Internet Protocol address associated with search queries" to six months. This is down from the 18 months it takes under current policy.
The move follows Google's September '08 decision to reduce its 18-month data retention period to nine months and Yahoo!'s December '08 pledge to anonymize user data within 90 days.
"This change is the result of a number of factors including a continuing evaluation of our business needs, the current competitive landscape and our ongoing dialogue with privacy advocates, consumer groups, and regulators – including the Article 29 Working Party, the group of 27 European national data protection regulators charged with providing advice to the European Commission and other EU institutions on data protection, " Microsoft said in a statement.
Microsoft says the new time limit will come into effect over the next 12 to 18 months, adding that the core components of its policy will remain the same.
At present Microsoft's policy is as follows:
As soon as Microsoft receives a Bing search query we take steps to de-identify the data by separating it from account information that could identify the person who performed the search. Then, at 18 months, we take the additional step of deleting the IP address, the de-identified cookie ID and any other cross-session IDs associated with the query.

If you think that's creepy I hope you never find out how long Google keeps that information.

Not scared.
Maybe it is because they cannot get your Mac address?
Demographics and also tailoring searches just for you using the IP and cookies to keep track of what you like in a search.
Traffic engineers tracked YOUR data as you drove around. They tracked your USAGE data to optimize traffic intersections during busy hours for EVERYBODY. Tracking USAGE data is how ENGINEERS optimize their SERVICES to YOU.
If you have a problem with tracking USAGE data, start with traffic engineers. Have them remove their optimizations for intersections. That way, you can live in bliss at the red light or trying to make a right turn.
At least its better then Google. I am really beginning to dislike Google.
They have way too much information and after the breach at their China facility I am less inclined to embrace their cloud products.
This would be analogous to the search companies storing how many times you searched something. The difference is that they know what you search. It's not like the traffic engineers are listening in on your phone conversation when you pass the intersection.
in what other way can you optimize search queries if you don't know what people are searching for?
your argument about traffic engineers listening to phone conversations doesn't quite relate. listening to phone conversations isn't related to traffic engineering and would indeed be morally wrong if this type of thing was happening. knowing what people search for to optimize search queries is related to tracking usage data.
i understand the fear people have about data being tracked, especially if there is a chance it can be used against them or for the wrong purpose. I just don't understand why so much mistrust. Can't a company that's dedicated to providing a search engine track data so it can gain an edge or stay on top?
Side note.... Bing sucks as a search engine. If you disagree let me know why I'd be curious.
