Private Vulnerability Testing for User Oversharing
Researchers formalise how combinations of seemingly innocuous user attributes can enable re-identification, offering a privacy-testing framework relevant to GDPR data-minimisation obligations.

arXiv:2611.05779v1 Announce Type: new Abstract: Users can inadvertently increase their vulnerability to privacy attacks by oversharing personal information. In particular, the combination of individually innocuous attributes can place a user in a sufficiently small population to enable linkage or re-identification attacks. We present a privacy-preserving mechanism that allows users to determine whether the information they disclose places them below a predefined population threshold, without re
Editorial Analysis
Enterprises collecting multiple user attributes may unknowingly create re-identification risk; formal vulnerability testing can preempt GDPR enforcement actions.
