Policy Briefing — UK ICO Consults on Biometric Classification Guidance
The UK Information Commissioner’s Office opened consultation on 10 June 2024 for new biometric classification and identification guidance, flagging heightened DPIA, accuracy, and governance controls for AI deployments.
Executive briefing: The UK Information Commissioner’s Office (ICO) published draft Chapters 3 and 4 of its biometrics guidance for consultation on 10 June 2024. The documents clarify how data protection law applies to biometric classification and identification systems, stressing fairness, proportionality, and accountability obligations before organisations deploy AI for recognition, categorisation, or risk scoring.
Key obligations
- Lawful basis and necessity. Controllers must evidence a lawful basis and demonstrate biometric processing is necessary and proportionate to the stated purpose.
- Accuracy and testing. Draft guidance requires rigorous pre-deployment and ongoing accuracy testing, including demographic performance analysis to prevent bias.
- Data Protection Impact Assessments. Organisations must complete DPIAs covering model purpose, data sources, evaluation metrics, and mitigation controls before implementation.
- Human oversight and intervention. The ICO expects clear escalation paths, override mechanisms, and documented human review for high-risk use cases.
- Vendor accountability. Contracts must allocate responsibilities for dataset provenance, model updates, incident response, and subject access handling.
Consultation timeline
- Feedback deadline. Stakeholders can submit comments until 12 August 2024.
- Final guidance. The ICO plans to issue final biometrics guidance later in 2024, completing its AI and data protection update series.
Program actions
- Inventory biometric use. Catalogue facial recognition, voice analytics, gait analysis, and behavioural biometrics across the enterprise.
- Refresh DPIAs. Align impact assessments with the ICO’s detailed risk questions, covering bias testing, human review, and data minimisation.
- Bias evaluation. Commission independent testing for demographic differentials and document remediation plans.
- Vendor audits. Update procurement due diligence to ensure suppliers provide training data documentation, performance evidence, and incident reporting commitments.
