Abstract
Background. Many criminal acts today are mediated by the creation and distribution of tipped texts, in connection with which law enforcement agencies are faced with the task of identifying their typists. However, to date, forensic science has not developed special methods for solving this problem. The study proposes to introduce keystroke dynamics studies into crime detection and investigation activities, for which it is first necessary to develop the issue of the possibility of using information about it from the standpoint of forensic science. This study focuses on the objective limitations that may arise when studying keystroke dynamics associated with its variability. The purpose of the study is to systematize the factors that can influence the stability of keystroke dynamics, to establish the direction of their influence and to determine how they should be taken into account during the examination. Materials and methods. The study is based on an interdisciplinary approach, integrating the achievements of the computer-technical sphere of knowledge into the legal subject field. The main method was systematization, due to which individual confounding factors were identified and their interrelation was established. The author also turned to the questionnaire method to assess the relevance of the study and identify the potential for enhancing the negative role of individual factors considered. Results. A system of factors influencing the stability of keystroke dynamics was built, dividing them into two groups: internal and external; characteristics of each element of the system are provided; their influence on the stability of the skill was assessed. Conclusions. Confounding factors have a predictable effect on keystroke dynamics, in connection with which they can be checked in the process of conducting an examination to adjust identification conclusions, and their direct consideration is an important component for conducting diagnostic studies. In addition, changes in keystroke dynamics under the influence of confusing factors do not exclude the possibility of identifying the typist.
