> (Browser history is also stored online for most browsers these days, and especially if you use Chrome then Google already have your history anyway).

Chrome Sync supports optional client-side encryption, and Firefox Sync always uses client-side encryption.

If they care about your browser history specifically, then in a battle between one individual and a government-level adversary, I'd bet on the latter; it's unlikely they'd try to break the encryption when they could use keyloggers, cameras, or any number of other methods that work fine on targeted individuals. (Or,

But if they care about doing blanket capture and analysis of everyone's history, then yes, I think the encryption used by Chrome and Firefox should work. Security bugs are always possible, of course, and browsers are quite notorious for them, but the more widely a security bug is exploited, the more rapidly it'll be detected and fixed.

Being accused of a precrime is one thing to be concerned about. It's happened to quite a few people. People who planned an event similar to "Improv Everywhere" in London were captured and detained before they could do something which was not even illegal... An Irish guy got questioned for a solid 12 hours and sent home for an innocuous tweet. Another person was detained and had his home trashed for quoting a movie on Facebook. This happens all the time. Imagine if you are a writer for a mystery novel, you want to do some research, and then someone close to you dies. Now your research queries are going to be used to make you look guilty. Yeah, an 'innocent' man has nothing to fear from the law, except they do, as you can clearly see if you ever have heard of http://www.innocenceproject.org/.

This is certainly a concern. However, I believe that if the NSA or local law enforcement have a way to mine your search history internal to Google, they will not be stopped in this endeavor just because you told Google not to save your search history. They can just gather the data in real time and maintain their own history for you.

The solution to this is not to turn off Google's search history, but to use a search engine (like DDG) who purportedly have security and anonymity built in.

Yes, I do. But I also believe that they would more easily access my computer after I inserted the master password, or detain me with false accuses until I give up, and maybe more. We're talking about organizations that do not abide by the law. But one thing is to worry for the NSA coming after you, another is to keep your history hidden from Google.

Can you explain to me why you don't want Google seeing your search history? Remember: you are voluntarily submitting these searches to Google. Why would you search using an engine you don't trust? Or is it that you don't want them to have the historical data?

I submit that if you don't want Google to know about your searches, you should not use Google (or at the very least, not use Google with a browser logged in to a Google service).

Hi Nathan, I just wanted to point out that is different to try to hide something from the NSA and from Google, I didn't mean to say that is good or bad to hide things from Google when using their services.

That said, I can imagine someone who wants to use a search engine that he doesn't trust (because the results are better but wants to keep his privacy): for example a girl may want to search for pregnancy tests but she may dislike to be later targeted by ads about that.

You are right that one could simply avoid the service or at least avoid to be logged in, but most people are oblivious of these things.

Yeah, I can understand going in and deleting specific things in your history if Google keeps serving you ads about them. But turning off the entire history seems like overkill.

(And your point about hiding from the NSA vs. Google is what I was trying to get at in my comment above, which for some reason got downvoted quite heavily).

Even if you are logged out, they have 56 touch points (plugins, bookmarks, etc) to determine who you are.

I find it quite useful for the auto-completition feature, esp. when I switch between different machines.

But still, I deactivated it. The potential disagreement surpasses the benefits. Whenever someone is looking at my screen, I'm always concerned that an embarrassing previous query pop up.
