Original Abstract

Apart from the uniqueness of the DBS, another crucial aspect is its stability. Individuals providing signatures are often under stress, due i. a. to the importance of the situation in which they are signing. Stress is indeed one of the most common emotions in human life, and most frequently a negative one. Our paper describes experiments that addressed the influence of stress on the dynamic biometric signature. In the experiments are used extreme situations experienced by participants in so-called survival courses at the University of Defence of the Czech Republic. The participants performed a series of difficult tasks and gradually entered a state of physical and psychological exhaustion, hunger, sleep deprivation and hence stress. Further, they underwent the d2 Test of Attention and signed their names on a Signotec tablet that recorded the biometric characteristics of the signature. The results showed that the stability of their dynamic biometric signatures remained unchanged as the physical and psychological load on the participants increased. The variability of individuals’ signatures did not change significantly in the separate phases of the experiment. Has been demonstrated that a handwritten signature acquired through long-term practice and the consolidation of the dynamic stereotype composed of the physiological, psychological, anatomical and motor characteristics of each individual is so automated and stored so deep in the human brain that its inadvertent performance does not prevent the performance of other processes in the cortex. This sufficiently protects the DBS from external influences.
