Which federal agency's guidance warns against unsubstantiated claims about biometric tools?

The Federal Trade Commission (FTC) is the agency whose guidance emphasizes caution against making unsubstantiated claims about biometric tools. The FTC’s role involves protecting consumers by enforcing laws that prevent deceptive or unfair practices in the marketplace. This includes closely scrutinizing claims made about products, including biometric technologies, to ensure that companies do not mislead consumers about the effectiveness or accuracy of these tools.

The guidance from the FTC advises businesses to ensure that their marketing claims about biometric technologies, such as facial recognition and fingerprint scanning, are backed by adequate evidence. This is crucial given the concerns around privacy, security, and the potential for bias in biometric systems. Thus, the FTC's focus on evidence-based claims is intended to promote transparency and accountability in the use of biometric technologies, ensuring consumers are adequately informed about the products they are using.

Other agencies listed, like the FDA (which oversees medical devices), NIST (which develops standards and guidelines for technology), and FBI (which handles law enforcement and criminal justice issues), focus on different aspects of technology regulation and do not specifically address the marketing practices related to biometric tools in the same context as the FTC.
