This article describes the development of software to identify a user based on his or her keystrokes. Biometric authentication, particularly methods based on behavioral characteristics, is becoming increasingly popular. This is due to its ability to provide security without the need to remember passwords. The development of a biometric identification system based on the typing of a text entered by the user on the keyboard is an attractive solution, as it not only has the potential to provide a fairly reliable identification, but also does not require significant costs for special equipment. This paper discusses parameters that affect typing, including keystroke time, typing speed, error rates, and others that depend on individual user characteristics. The paper also discusses the drawbacks of biometric identification, particularly the impact of external factors such as fatigue or distraction on authentication accuracy. Based on the analysis of parameters, known methods and approaches to biometric identification by keystroke style, a new verification algorithm is proposed. It is based on the analysis of the time intervals between keystrokes and key searches, which allows to determine the correspondence between the stored user profile and the current keystroke. In order to reduce the influence of external factors, the use of a fixed text of at least 300 characters is recommended. The effectiveness of the developed software based on the proposed identification algorithm is confirmed by the results of the experiments conducted with the developed software application. The results show sufficient reliability and accuracy in the identification process. The work is of practical importance for the development of new security methods in information technology and opens new opportunities for the implementation of biometric systems in various fields.
