Special Knowledge in Review of Keystroke Dynamics

Widespread use of digital technologies has led to the emergence of a problem in criminal proceedings related to the defi nition of the boundary where the area of general professional competence of an investigator ends and the area of special knowledge begins. This is also characteristic for the detection, fi xation and investigation of keystroke dynamics. The article describes the competence of a specialist to detect this digital trace; the investigator’s authority to obtain keystroke dynamics samples for comparative study and his duty to evaluate the results of such study; the algorithm of expert’s actions in the production of computer-technical expertise of keystroke dynamics. As a result, the conclusion is formulated about the necessity of coordinated actions of the mentioned participants of criminal proceedings, as well as further study of issues in this area to reveal the depth of the forensic value of keystroke dynamics.
