Private Communication Using Untrusted Service Providers

Our digital lives have become increasingly interdependent and interconnected. Such interconnections rely on a vast network of actors whose trustworthiness is not always guaranteed. Over the past three decades, rapid advances in computing and communication technologies have enabled billions of users with access to information and connectivity at their fingertips. Unfortunately, this rapid digitization of our personal lives is also now vulnerable to invasions of privacy. In particular, we need to worry about the malicious intent of individual actors in the network as well as large and powerful organizations such as service providers and nation states. Given such an untrusted world, we illustrate some of the privacy challenges by focusing on the following research questions: can we design a scalable infrastructure for voice communication that will hide meta-information regarding who is communicating with whom? The solution to this challenge has significant ramification on diverse data management problems such as designing scalable systems for oblivious search for documents from public repositories as well as private query processing over public databases. These are some of the iconic problems that must be solved before we can embark on building trusted platforms and services over untrusted infrastructures.
