facial recognition (FR)
What It Means
Facial recognition technology doesn't actually 'recognize' specific people like humans do. Instead, it converts facial features from photos into mathematical patterns (like digital fingerprints) that can be compared to determine if two images show the same person.
Why Chief AI Officers Care
This distinction is crucial for AI governance because it affects privacy compliance, bias testing requirements, and liability - the technology creates permanent digital profiles that can be misused, requires careful accuracy monitoring across demographics, and may violate regulations if deployed without proper safeguards.
Real-World Example
A retail store's security system doesn't know 'John Smith' - it creates a mathematical pattern from John's face that gets flagged if the same pattern appears again, which could incorrectly match someone who looks similar or fail to match John if lighting conditions change.
Common Confusion
Executives often think facial recognition 'knows' who people are like a human would, when it actually just matches mathematical patterns - meaning it can make mistakes, create false matches, and doesn't inherently understand identity or context.

Technical Definitions
NISTNational Institute of Standards and Technology
"Face recognition algorithms, however, have no built-in notion of a particular person. They are not built to identify particular people; instead they include a face detector followed by a feature extraction algorithm that converts one or more images of a person into a vector of values that relate to the identity of the person. The extractor typically consists of a neural network that has been trained on ID-labeled images available to the developer. In operations, they act as generic extractors of identity-related information from photos of persons they have usually never seen before. Recognition proceeds as a differential operator: Algorithms compare two feature vectors and emit a similarity score. This is a vendor-defined numeric value expressing how similar the parent faces are. It is compared to a threshold value to decide whether two samples are from, or represent, the same person or not. Thus, recognition is mediated by persistent identity information stored in a feature vector (or “template”)."Source: NISTIR_8280
