Sure, surfing the web in “incognito” or “private” mode might seem more secure than doing it with a totally unsecured browser—the phrases imply an air of security—but recent research and an overwhelming amount of anecdotal evidence from security experts indicates that so-called private browsing isn’t nearly as private as it’s cracked up to be. In fact, it’s not really private at all: routers, firewalls, proxy servers, RAM chips or the Domain Name System (DNS) cache all could have a record of your browsing history.
