ISO 27566 Clause 8.2 - Age Estimation Methods
Implement age estimation methods with documented accuracy across demographics, bias monitoring, privacy-preserving processing, and transparent communication about estimation confidence
Where this comes from
Provision: Clause 8.2 - Age Estimation Methods
Instrument: ISO/IEC 27566-1:2025
Citation: ISO/IEC 27566-1:2025, Age assurance systems -- Framework, Clause 8.2: Age Estimation Methods
Text version: ISO/IEC 27566-1:2025
Who it applies to
It applies when all of these are true:
- Service is likely to be accessed by children under 18
…unless:
- Age verification method is not Third-party age estimation or Multiple methods
What engineering work it implies
Sample acceptance criteria Landfall generates for this obligation:
- Estimation communicates an approximate age range rather than an exact age
- Accuracy is documented across demographics (age, gender, ethnicity) with bias monitoring and mitigation
- Biometric/behavioural processing is privacy-preserving (on-device where feasible; minimal retention)
- Estimation confidence and the fallback for low-confidence results are defined
- System handles null/empty input gracefully (no 500 errors)
