Question
Which of the following is the best example of an AI model that is trained to identify multiple points from input using a neural network to provide output for authentication?
- A. Facial recognition Correct
- B. Encryption key
- C. Open Authorization (OAuth)
- D. Bounding box
Explanation
Facial recognition uses a neural network trained to locate many landmark points on a face (eyes, nose, jawline) and compare them with an enrolled template to authenticate a person. An encryption key and OAuth are cryptographic and authorization mechanisms, not trained models. A bounding box only marks where an object sits in an image and does not authenticate anyone.
