Default configurations - Recognition

In Default configurations, the Recognition section controls facial authentication and security detection settings. These settings enhance session security by verifying user identity and detecting unauthorized activity.

This section includes:

  • Facial Recognition and Authentication – Verifies user identity through face recognition.

  • Shoulder Surfing Detection – Detects unauthorized individuals viewing the screen..

  • Mobile Phone Detection – Identifies and blocks attempts to capture the screen with a mobile device.

Note

If you enable any recognition features, the user’s device must have an integrated or external USB webcam accessible to the SessionGuardian client. Refer to Preparation of Work Environment for hardware requirements and setup guidelines.

Refer to the following table for configurable settings in the Recognition section and their descriptions.

Run Once 

Performs a single facial recognition and authentication check at the start of a user’s session. The system does not require additional face verification during the session.

Continuous Face Recognition 

Enables ongoing facial recognition throughout the session instead of a single authentication at login.

The system requires a high-quality profile photo stored in the SessionGuardian console. If a profile picture is missing, users are prompted to take one during authentication.

Enabling this setting also unlocks additional configuration options:

  • Processing Snapshot Frequency (ms) – Defines how often the system performs recognition and authentication checks. Recommended: 300 ms

  • Face ID Confidence (%) – Sets the minimum confidence level required for successful facial recognition. Recommended: 98%

  • Face Detection Delay (ms) – Determines how long the system waits before taking action if the authorized user is not detected. Recommended: 45000 ms (in SG version 2.2 or 20000 ms (in SG version 2.3)

  • Protection Screen Timeout (sec) – Specifies how long the system waits for the user to reappear before locking access. Recommended: 600 sec

    • Mobile Device Protection Screen Timeout (sec) – Determines how long a lock screen appears when a mobile device is detected. Default: 5 sec

    • Mobile Device Match Confidence (%) – Sets the minimum confidence level required for mobile device detection. Default: 90% (in SG version 2.2) or 98% (in SG version 2.3)

  • Camera Device Detection

    • Camera Device Detection Frequency (ms) – Defines how often the system analyzes the user's machine for a webcam. Default: 500 ms

    • Camera Device Protection Screen Timeout (sec) – Determines how long a lock screen appears when a webcam not detected. Default: 5 sec
