       | getting built into more and more consumer products.

       | A quick summary of The Decoupling Principle: _Separate WHO you
       | are from WHAT you do_
       | 
       | An example is Apple's iCloud relay. When you browse a URL, it is
       | encrypted and sent to the first server, owned by Apple. This
       | knows WHO you are, but not what you are browsing. The Apple
       | server then sends your request to the second server, operated by
       | a third party such as Fastly. This server gets to see your URL,
       | but it only has Apple's IP address, so it knows WHAT is being
       | browsed, but not WHO you are.

       | Nice to see this here; happy to discuss our paper with folks.
       | 
       | The TLDR is that there's a classic idea (dating back at least to
       | Chaum's early work if not earlier) that we can get privacy in
       | networks by splitting knowledge across multiple parties and/or
       | multiple architectural elements.
       | 
       | We explore that idea and give examples of where we and others
       | have applied it recently (in some of our services at Invisv and
       | things our colleagues elsewhere have built).
