Transparency Note: Azure Cognitive Services Face API

Facial recognition is an important and useful technology that can improve efficiency, security, and customer experiences. Face API is a building block for creating a facial recognition system. A facial recognition system includes the technology as well as the people who will use it, the people who will be subject to it, and the environment in which it is deployed. Creating a system that is fit for purpose requires an understanding of how the technology works, its capabilities and limitations, and how to achieve the most accurate results. This Transparency Note is intended to help you understand how Face API works, the choices you can make as a system owner that influence accuracy, and the importance of thinking about the whole system, including the technology, the people, and the environment.
