Enhancing Protections through the Collective Auditing of Algorithmic Personalization

Introduction

The structure of the current data ecosystem carries grave threats to individuals' privacy and autonomy, facilitates discrimination, promotes social fragmentation, and threatens our ability to govern ourselves. Many of these concerns stem specifically from algorithmic personalization—the practice of providing individuals with personalized opportunities, information, or experiences, on the basis of their personal data and on patterns learned from others' data.

Problem Statement

Despite the urgency of the algorithmic personalization problem, the mathematical toolkit for studying and auditing problematic algorithmic personalization remains extremely limited—particularly if we wish to do so in a manner that provides formal privacy guarantees.

Project Goal

The goal of this proposal is to tackle this important problem head-on by establishing the mathematical foundations needed to study algorithmic personalization and to collectively audit personalization systems while guaranteeing privacy to participants. Such tools could transform our collective ability to make the best possible use of our data while ensuring autonomy, privacy, and overall positive social impact.

Vision and Objectives

My vision focuses on three core objectives:

1. Building new mathematical concepts and definitions allowing us to articulate, prioritize, and study personalization-based problems.
2. Addressing the key algorithmic challenges of privacy-preserving auditing of personalization systems.
3. Integrating a deep understanding of the broader legal and ethical context into our approach.

Research Strategy

For each of these components, the proposal maps out a concrete research strategy, including preliminary steps that indicate the feasibility of this groundbreaking project.
