livenessMode

Widget liveness check mode.

Details

Attribute: liveness-mode

Type: LivenessMode

Default value: LivenessMode.None

LivenessMode

Member	Value	Description
None	0	Without liveness check by movement.
Move	2	Enables the liveness check by movement (liveness move).
Passive	3	Compatibility; it has no effect (see below).

Morphology

import { LivenessMode } from '@facephi/selphi-web-component';

selphi.livenessMode = LivenessMode.Move;

Description

Select the liveness check mode for facephi-selphi-widget. The recommended way to enable liveness move is to define livenessMode = LivenessMode.Move together with the steps (livenessMoveSteps, or its recommended name moveSuccessfulAttempts).

Defining only the steps (without Move) still activates the move for compatibility, but it is deprecated: livenessMode = LivenessMode.Move will be mandatory in the next major version. The value Passive has no effect and will also be removed in the next major version.

Behavior

The result for incomplete or contradictory combinations depends on settingsStrictness:

Scenario	Tolerant (default)	Strict
Move + steps > 0	Move with those steps	Move with those steps
Move + steps = 0	Move with 3 steps + warning	Blocking error
Steps > 0 without Move	Move + deprecation warning	Move + deprecation warning
None (or not specified)	Without liveness check	Without liveness check
Passive	Discarded (no effect)	Discarded (no effect)
