Veil has two modes. One is a image-based browsing. Another is focused on eliminated RAM artifacts and DNS caches on the operating systems side. I agree there are a lot of solutions, and we don't solve all the problems. The point is that we wanted to challenge the current notion that only browsers can provide incognito mode. We were thinking is there a way for developers to do this since they are the ones delivering the content in the first place.
The point of the paper was to create discussions like this! Thanks for your thoughts. I really appreciate it.
