Liveness Detection
3 min
Overview
Liveness Detection's purpose is to ensure that agents are not simply putting a photograph of themselves in front of their camera. The detection model verifies that the camera is looking at a living person.
In most cases, we recommend only modifying the settings under "Feature Settings - Common". Modification of settings under "Feature Settings - Advanced" should only be done with support from Secure WFM SMEs and guidance from IT.
Feature Settings - Common
- TRS_LIVENESS_DETECTION_ENABLED
- Enable liveness detection
- Default: True (enable it)
- TRS_LIVENESS_FAILURE_LIMIT
- Controls how often a liveness failure event will be raised. The number specifies the concurrent number of times liveness can fail before an event is raised. Increase this number to generate fewer liveness failure events.
- Default: 3
- TRS_LIVENESS_REPEAT_INTERVAL
- This setting controls how long the system should wait (in seconds) after a liveness failure event to re-enable liveness detection. Increase this number to generate fewer liveness failure events.
- Default: 5
- TRS_LIVENESS_VIOLATION_TIMEOUT
- Timeout for Liveness Detection.
- Default=10
Feature Settings - Advanced
- TRS_LIVENESS_CHECK_FREQUENCY
- Specifies the number of times a face should be found before checking for liveness (i.e. don't check for liveness if there is no face visible in the camera). Increase this number to generate fewer liveness failure events.
- Default: 50
- LIVENESS_DETECTOR_MODEL_THRESHOLD
- Lower confidence limit for liveness detection below which "fake" is the result
- Default: -0.3
- LIVENESS_DETECTOR_MODEL_CONFIDENCE
- Higher confident limit for liveness detection above which "fake" is the results
- Default: 0.5
