fingerprinting deck

# Brad Hill (2 days ago)

We discussed in yesterday's call fingerprinting vs. stateful tracking and I made reference to a discussion deck on the topic I prepared for TPAC in 2012.

Here's the link I promised:

Among many other observations, I should thank Andy Steingruebl for the suggestion that preventing browser fingerprinting is actually an instance of confining covert channels as described by Lampson in "A note on the confinement problem" from 1973, which basically states that these channels cannot be eliminated, only limited in their bandwidth through very careful system construction. It's been a very useful lens through which to view the problem.

Here's a link I found to the paper text: www.cs.utexas.edu/~shmat/courses/cs380s_fall09/lampson73.pdf
