摘要：Five years ago, “Privacy-enhancing technologies for the Internet” [23]
examined the state of the then newly emerging privacy-enhancing technologies.
In this survey paper, we look back at the last five years to see what has changed,
what has stagnated, what has succeeded, what has failed, and why. We also look
at current trends with a view towards the future.
