Identity by Design, Demographics by Accident: Demographic Leakage and Suppression in Behavioral Biometric Embeddings
Research reveals that behavioural biometric embeddings designed for authentication inadvertently encode demographic data, raising discrimination and privacy risks under GDPR and the EU AI Act.

arXiv:2608.28921v1 Announce Type: new Abstract: Behavioral biometric authentication (BBA) systems use deep learning models to transform biometric signals, such as eye movements, voice, keystroke/touchstroke dynamics, and gait, into identity embeddings for user authentication. While designed to encode identity, these embeddings may inadvertently reveal sensitive demographic attributes, including gender, age, and height. Consequently, an adversary with access to the authentication model can infer
Editorial Analysis
Enterprises using behavioural biometrics may face regulatory exposure if authentication embeddings encode protected demographic attributes without appropriate safeguards.
Commission a privacy impact assessment for behavioural biometric systems to test for demographic attribute leakage and document mitigation measures.
Behavioural biometric systems may inadvertently process demographic data, creating EU AI Act and GDPR compliance risk requiring proactive assessment.
