Rethinking Data Minimization from a User-Centered Approach: A Paradigm Shift

Tuesday, September 12, 2023 - 8:45 am9:00 am

Tanusree Sharma, University of Illinois at Urbana Champaign


Data minimization is a legal and privacy-by-design principle mandating that online services collect only data that is necessary for pre-specified purposes. In traditional system-based approaches that attribute the sole responsibility for data minimization to service providers, it becomes vital to involve users in shaping the appropriate data compliance practices.

In this talk, I will talk about (a) current misunderstandings regarding data minimization among users, (b) surfaces how users reason about the necessity of data in relation to search result quality, and (c) impact of factors on user decision-making with regards to data minimization. The goal is to design actionable mechanisms that provide users with greater agency over their data through user-controlled data minimization.
