Artificial Intelligence and Machine Learning in Identity Systems

Before · SP 800-63-3

After · SP 800-63-4

Identity solutions use artificial intelligence (AI) and machine learning (ML) in various ways, such as improving the performance of biometric matching systems, automating evidence or attribute validation, detecting fraud, and even assisting users (e.g., chatbots). While the potential applications of AI and ML are extensive, these technologies may also introduce new risks or produce unintended negative outcomes.

The following requirements apply to all uses of AI and ML in the identity system, regardless of how they are used:

• All uses of AI/ML SHALL be documented and communicated to organizations that rely on these systems. The use of integrated technologies that leverage AI/ML by CSPs, IdPs, or verifiers SHALL be disclosed to all RPs that make access decisions based on information from these systems.

• All organizations that use AI/ML SHALL provide information to any entities that use their technology on the methods and techniques used for training their models, a description of the data sets used in training, information on the frequency of model updates, and the results of all testing completed on their algorithms.

• All organizations that use AI/ML systems or rely on services that use these systems SHOULD implement the NIST AI Risk Management Framework ( [NISTAIRMF] ) to evaluate the risks that may be introduced by such systems.
• All organizations that use AI/ML systems or rely on services that use these systems SHALL perform and document privacy risk assessments for personal information and data processed by such systems. References
