Mobile Device Iris Authentication Illuminance Adaptation

The patent implements dynamic adaptation of the authentication process based on external illuminance conditions. The controller adjusts the authentication method in real-time by detecting ambient light levels and selecting appropriate algorithms (first algorithm for low illuminance, second algorithm for high illuminance). This dynamic adjustment maintains high detection accuracy across varying lighting conditions while managing system complexity through conditional logic rather than multiple fixed systems.

The patent changes operational parameters based on external conditions by switching between different authentication algorithms according to illuminance levels. The first algorithm is applied when external illuminance is below a threshold, and the second algorithm is applied when illuminance exceeds the threshold. This parameter-based adaptation optimizes detection accuracy for forged irises while keeping the system manageable through conditional parameter selection.

The system dynamically selects between multiple authentication algorithms based on real-time illuminance detection, rather than executing all methods sequentially. This dynamic selection reduces processing time by choosing the most appropriate algorithm for current lighting conditions while maintaining high detection accuracy. The controller efficiently switches between the first algorithm (for low illuminance) and second algorithm (for high illuminance) based on ambient light thresholds.

The patent applies only the necessary level of authentication complexity required for current conditions. By using conditional logic to select between algorithms based on illuminance thresholds, the system performs partial action - applying the sufficient level of verification needed without always executing the most complex methods. This reduces unnecessary processing time while maintaining security effectiveness.
