The Face Compare API in JavaScript is typically part of broader facial recognition services, such as those provided by Microsoft Azure's Face API or AWS Rekognition. This API allows developers to compare two faces to determine if they belong to the same person. Below is a detailed description of its functionalities and a common use case.

Use Case: Employee Verification System

Scenario: An organization needs to verify employees as they enter the premises. The system compares the live capture of an employee's face with their stored profile picture to ensure identity verification.

Steps:

1. Capture Live Image: Use a camera to capture a live image of the employee as they approach the entrance.
2. Retrieve Profile Image: Retrieve the stored profile image of the employee from the database.
3. Compare Faces: Use the Face Compare API to compare the live image with the profile image.
4. Grant Access: If the faces match, grant access to the premises; otherwise, deny access and alert security.

Benefits:

• Enhanced Security: Ensures only authorized personnel enter the premises.
• Efficiency: Automates the verification process, reducing the need for manual checks.
• Real-time Processing: Provides instant feedback, making the entry process seamless and quick.
