Face Authentication

This page explains the features of the Face Authentication setting section in MonitorDog Admin.

MonitorDog provides a powerful identity verification method by analyzing facial data through custom AI models. Through this page, you can configure whether to enable authentication features, set the security level for Biometric (Liveness) detection, and define response policies for authentication failures.

The rules configured on this page are applied as the default detection rules for new users. If you wish to apply specific rules to a particular user, you can change individual settings on the User Management Page.

⚠️ Only Manager level administrators or higher can access this page.

Face Authentication Item Settings​

Configure the timing and detailed options for Face Authentication.

Face Authentication Setting Page

Face Login​

Adds a face authentication step in addition to ID/PW at login to prevent account hijacking.

Face Authentication Login Setting Section

Biometric Security Level​

This option verifies actual human biological responses (Liveness Detection) to block spoofing attempts using photos, videos, or masks. Choose the appropriate strength based on your organization's security policy.

  • Standard - Fast Match : Instantly authenticates without liveness checks, providing fast usability optimized for daily work environments.
  • High - Active Liveness : Authenticates after liveness checks to prevent spoofing with photos or videos, making it suitable for high-security environments

Failure Response Policy​

The user is logged out automatically after 10 consecutive failed attempts, and ID and password entry is required to log in.

Face Authentication on No Person Unlock​

Sets the requirement for face authentication to unlock the screen when a user returns to work from a 'No Person' state.

Face Authentication No Person Setting Section

Biometric Security Strength​

Similar to the login settings, you can choose between Standard (Fast Auth) and High (Active Liveness). Since 'No Person' unlocking occurs frequently, consider the balance between security and convenience.

Failure Response Policy​

If face authentication attempts continue to fail, step-by-step security measures are applied.

  • Step 1 (5 Consecutive Failures): The screen is temporarily locked for 10 seconds, and retries are restricted. (Fixed System Policy)

  • Step 2 (10 Consecutive Failures): The screen is completely locked, and can only be unlocked using one of the methods below.
    • Auto Lock - User Manual Unlock: The user unlocks the screen by manually entering their account password.
    • Auto Lock - Admin Approval Unlock: The lock is only released after an administrator approves the user's unlock request on the dashboard.

Q. What happens if I disable Face Authentication for 'No Person'?

A. To prevent security gaps, the 'No Person' policy is automatically switched to 'Password Entry'. If you wish to change this to another policy, you can adjust it in the Detection Rule - No Person Settings.

Q. I don't want my face images to be stored on the server!

A. MonitorDog prioritizes user privacy and strictly separates authentication data from security logs.

  • Face Authentication Data: During authentication, only numerical Feature Vectors are extracted from the transmitted data. The original images are immediately destroyed after analysis and are never stored anywhere. They are managed as encrypted data that cannot be reconstructed, so you can use the service with peace of mind.
  • Event Logs: However, when a security event occurs (such as success/failure of face authentication or violation of detection rules), webcam and monitor screen captures are recorded for monitoring purposes, just as before. These are used as legitimate records for security auditing.
