Question
Which of the following is NOT a use case for Azure AI Face service?
A. Granting access to buildings based on facial recognition
B. Blurring faces in videos to protect privacy
C. Verifying user identity through face comparison with a trusted image
D. Analyzing emotions from facial expressions
Answer
D. Analyzing emotions from facial expressions
Explanation
Analyzing emotions from facial expressions is not a use case for Azure AI Face service. While the Face service can detect faces and extract various attributes such as age and gender, Microsoft has retired the functionality for predicting emotions due to concerns about potential misuse and limitations in accuracy. Azure AI Face service offers AI algorithms for detecting, recognizing, and analyzing human faces in images. It has various use cases, including:
- Verification: Confirming user identity by comparing a face to a trusted image (e.g., ID card).
- Liveness detection: Verifying user presence in front of the camera (anti-spoofing).
- Touchless access control: Granting access based on facial recognition.
- Face redaction: Blurring faces in videos for privacy protection.
In line with Microsoft’s commitment to responsible AI, access to the Azure Face service is controlled to ensure its ethical and fair use. This means the service is currently limited to qualified Microsoft managed customers and partners.
Granting access to buildings based on facial recognition, blurring faces in videos to protect privacy, and verifying user identity through face comparison with a trusted image are all valid use cases for the Face service.
