The paper concerns the influence of memory, forgetting and timing issues on the security of mobile applications. The designed framework system was used to further elaboration of the automatic measure, which estimates the quality (strength) of unlock gesture patterns. The data analysis described in detail presents the relations between human subjective ratings of patterns’ complexity and memorizability levels in regards to computed values of quality measure and real-life time spans needed to enter and re-enter the pattern.
