NIST AI and ISO 42001, and EU AI Act

1. NIST AI Risk Management Framework (NIST AI RMF)

The National Institute of Standards and Technology (NIST) provides the AI Risk Management Framework (RMF) to help organizations manage AI risks. NIST's RMF is designed to foster trustworthiness and reduce risks in AI applications.

Key Steps:

1. Map AI Risks:

   • Identify the context, objectives, and potential impacts of AI implementation.
   • Determine potential risks based on factors like fairness, transparency, and bias.

2. Measure AI Risks:

   • Quantify and assess the AI system's risks, especially related to accuracy, reliability, and explainability.
   • Use metrics and models to evaluate how AI models perform under different conditions.

3. Manage AI Risks:

   • Develop and implement controls to mitigate identified risks.
   • Adapt AI policies, frameworks, and operational processes to minimize adverse effects and respond to changes.

4. Govern AI Risks:

   • Create policies, roles, and responsibilities around AI usage.
   • Regularly update risk management protocols to ensure continuous improvement.

Examples:

• A healthcare organization using AI for diagnostics maps risks (such as incorrect diagnosis), measures risks with reliability testing, manages risks with controls (e.g., adding human oversight), and governs by setting policies for AI use.

2. ISO/IEC 42001 – AI Management System Standard

ISO/IEC 42001, expected to be released soon, aims to establish a framework for managing AI and integrating trustworthy principles. It offers guidelines to develop, deploy, and manage AI systems consistently.

Key Steps:

3. Evaluation and Continuous Improvement:

   • Regularly evaluate AI performance, monitor for risks, and compare actual results against expected outcomes.
   • Gather feedback and continuously improve AI model accuracy, compliance, and ethics.

4. Documentation and Transparency:

   • Keep records for AI decisions and operations, ensuring auditability and transparency.
   • Make AI system information accessible to relevant stakeholders for accountability.

Examples:

• A company deploying facial recognition AI documents policies to prevent bias, continuously monitors model accuracy, and keeps detailed records of system decisions for transparency.

3. European Union (EU) AI Act

The EU AI Act establishes regulations to ensure the safe and ethical use of AI within Europe. It categorizes AI systems based on risk levels and imposes requirements accordingly.

Key Steps:

1. Risk Categorization:

   • Classify AI applications as Unacceptable, High-Risk, Limited-Risk, or Minimal-Risk based on potential societal impact.
   • Apply stricter controls to high-risk AI applications, such as in healthcare, law enforcement, and finance.

2. Compliance Requirements for High-Risk AI:

   • High-risk AI systems must undergo risk assessments, testing, and validation.
   • Specific requirements include ensuring data quality, transparency, and accountability through external audits and certifications.

3. Transparency and Information Requirements:

   • Ensure AI transparency by clearly labeling AI-generated content and disclosing interactions with AI systems.
   • For high-risk applications, inform users about how AI impacts their data and provide channels for user feedback.

4. Ongoing Monitoring and Auditing:

   • Regularly assess the AI system for compliance, bias, and fairness.
   • Organizations must report severe incidents or malfunctions within high-risk AI systems to regulators.

Examples:

• An AI-powered recruiting tool in the EU is classified as high-risk, undergoes regular bias testing, and discloses to applicants that an AI system is involved in decision-making.

Comparison Table: NIST AI RMF vs. ISO 42001 vs. EU AI Act

Implementing the EU AI Act involves adhering to a set of requirements focused on minimizing risks associated with high-risk AI systems while promoting transparency, accountability, and user rights. The EU AI Act establishes a risk-based framework with specific obligations for developers and users, depending on the risk level of the AI applications they deploy.

The Act has categorized AI systems into different risk levels:

1. Unacceptable Risk: Banned AI applications, such as social scoring and certain forms of biometric surveillance.
2. High-Risk: Critical applications, like facial recognition and employment decision-making, which must comply with stringent requirements.
3. Limited Risk: Applications with transparency requirements, such as chatbots.
4. Minimal Risk: Low-risk applications, with no specific regulatory requirements.

For this guide, we’ll focus on implementing high-risk AI applications under the EU AI Act, as they involve the most rigorous compliance requirements.

Steps to Implement High-Risk AI Applications in Compliance with the EU AI Act
