The adversary is interested in tracking the user by any means necessary. However, mechanisms that are already being addressed by other projects will not be discussed in this document. | The adversary is interested in tracking the user by any means necessary. However, mechanisms that are already being addressed by other projects will not be discussed in this document. Private Browsing Mode, in particular, is primarily concerned with preventing the storage of browsing data. | ||
This document will focus on network-based tracking mechanisms. In particular, the adversary is interested in correlation of regular mode browsing to anonymous mode browsing, in obtaining location information, and in fingerprinting the user's browser characteristics. | |||
The adversary may have many motivations for doing this, but to keep scope simple, it may be best to assume that their primary motivation is to correlate user web activity for purposes of tracking users against their will for purposes of serving ads. A large class of adversaries (the ad networks) are interested in deploying semi-intrusive mechanisms to do so, in light of increasing number of users choosing to clear their cookies regularly, and in light of potential future [[Thirdparty Third Party Cookie]] protection mechanisms implemented by the major browsers. | |||
