How can you prevent history sniffing by online ad companies?
jhotz 1 year ago
I wasn't even aware of history sniffing until I ran across an article on Salon this morning about an FCC action against an online advertiser over it. Basically, it uses the function that changes the color of URLs that you've visited to see where you have been. They would put up a page that had thousands of links that were invisible to visitors, then they could see if the visitor had been to any of those linked sites. Here is the article about it, if anyone is interested: http://www.salon.com/2012/12/05/an_online_privacy_invader_gets_caught/
Is there any way to prevent this type of thing? Nothing really comes to mind, but I certainly don't like the idea of advertisers circumventing all of my privacy settings and knowing what sites I've visited in the past.
