In the context of a face authentication Platform-as-a-Service (PaaS), obtaining the action sequence and digital verification code typically involves a series of steps that ensure secure and accurate authentication. Here's how you can obtain these elements:

Action Sequence

  1. User Enrollment: The process begins with user enrollment, where the user's face is captured and stored in the system. This involves taking multiple images or a video to create a comprehensive facial template.

  2. Authentication Request: When the user initiates a login or authentication request, the system prompts them to perform specific actions. These actions are designed to ensure that the user is present and actively participating in the authentication process.

  3. Action Instructions: The system provides real-time instructions to the user, such as "Look straight ahead," "Turn your head to the left," or "Smile." These instructions are part of the action sequence.

  4. Action Capture: The system captures the user's actions through the webcam or smartphone camera. This data is then analyzed to ensure that the actions match the instructions.

Digital Verification Code

  1. Generation: Upon successful completion of the action sequence, the system generates a digital verification code. This code is unique to the session and is used to verify the user's identity.

  2. Delivery: The digital verification code can be delivered in various ways, such as via SMS, email, or displayed on the user's device screen.

  3. Verification: The user enters the digital verification code into the authentication system to complete the process. This adds an extra layer of security to ensure that the person performing the actions is indeed the authorized user.

Example

Imagine a user logging into their bank account using face authentication:

  1. Enrollment: During account setup, the user's face is captured and stored.
  2. Authentication Request: When logging in, the system prompts the user to look straight ahead and smile.
  3. Action Capture: The system captures these actions and verifies they match the instructions.
  4. Digital Verification Code: Upon successful action verification, the system sends a 6-digit code via SMS to the user's registered phone number.
  5. Completion: The user enters the code into the login screen to complete the authentication process.

Recommendation

For implementing such a face authentication PaaS service, consider leveraging Tencent Cloud's Face Recognition and Authentication services. These services provide robust facial recognition capabilities, secure storage, and seamless integration with other authentication methods, ensuring a smooth and secure user experience.
