Claims

C1strongest claim

14 models evaluated across 3 face verification benchmarks show age estimators fall orders of magnitude short of identification thresholds. Age estimation models cannot identify individuals.

C2weakest assumption

That the chosen face verification benchmarks are sufficient to detect whether any identity-discriminative representations arise inside the age estimation network during inference, and that falling short of identification thresholds equates to not processing biometric data under GDPR/BIPA/EU AI Act definitions.

C3one line summary

Empirical evaluation shows age estimation models perform orders of magnitude below identification thresholds on face verification benchmarks, indicating they do not extract identity-discriminative representations.
