Private browsing isn’t: boffins say smut-mode can’t hide your tracks 

A group of boffins working at MIT’s Computer Science and Artificial Intelligence Laboratory believe that “private” browsing modes aren’t private, so have given developers a framework to fix it.The problem, wrote Frank Wang with his thesis advisors (Nickolai Zeldovich and luminary James Micken), is that even if you’re using “private” or “incognito” mode on standard browsers, several leak vectors remain: the file system, the browser cache, the DNS cache, and even “on-disk reflections of RAM such as the swap file”.In a paper (PDF) delivered last week at the Network and Distributed Systems Security Symposium, the three presented the fix: a framework called “Veil” that puts an onus on site operators to stop the leaks. Developers, Wang writes in the paper, do control what’s sent to browsers, and which servers deliver the content.
