Wired:

I just Googled “alarm dust,” “alibi sweatshirt,” and “sleuth intelligence.” Then I shopped for industrial dehydrators, scanned a Pinterest page for concrete decks, and read something about nuclear war.

The thing is, I’m not in the market for a new dehydrator. Concrete decks aren’t really my style, and I still have no idea what “alarm dust” is. I didn’t visit any of these web sites of my own volition—a website called Internet Noise did, all to obscure my real browsing habits in a fog of fake search history.

This won’t actually “protect your privacy” but the idea is interesting – make your search history useless to advertisers. And, if you’re bored, watching the site do its searches is weirdly fun.
