🤖 AI Summary
This study addresses the persistent challenge of effectively ensuring privacy in scientific data anonymization, which is often hindered by a lack of actionable guidance. It introduces, for the first time, a systematic red team–blue team adversarial framework to this domain: the red team simulates realistic re-identification attacks, while the blue team iteratively refines anonymization strategies. The approach is empirically validated on real-world datasets using mixed-methods research. The work demonstrates that red teaming efficiently uncovers vulnerabilities in anonymization protocols and further delivers a reusable, publicly released framework and toolset for researchers. This contribution substantially enhances both the practicality and security of data anonymization practices in scientific research.
📝 Abstract
Recently, the data protection practices of researchers in human-computer interaction and elsewhere have gained attention. Initial results suggest that researchers struggle with anonymization, partly due to a lack of clear, actionable guidance. In this work, we propose simulating re-identification attacks using the approach of red teaming versus blue teaming: a technique commonly employed in security testing, where one team tries to re-identify data, and the other team tries to prevent it. We discuss our experience applying this method to data collected in a mixed-methods study in human-centered privacy. We present usable materials for researchers to apply red teaming when anonymizing and publishing their studies'data.
