[转载]Protecting Browser State from Web Privacy Attacks

信息来源：http://crypto.stanford.edu/sameorigin/

Through a variety of means, including a range of browser cache methods and inspecting the color of a visited hyper- link, client-side browser state can be exploited to track users against their wishes. This tracking is possible because per- sistent, client-side browser state is not properly partitioned on per-site basis in current browsers. We address this prob- lem by reopening the general notion of a "same-origin" policy and implementing two browser extensions that enforce this policy on the browser cache and visited links.
