How it happens

A biometric system, built for an ostensibly different purpose like age estimation or access control, is used or extended to infer one of the specifically prohibited sensitive categories from a person's biometric data.

Why it matters

These categories map directly onto UK GDPR's special category data; inferring them from biometrics compounds a data protection breach with a standalone AI Act prohibition.
