DEVELOPMENT OF A USER AUTHENTICATION METHOD BASED ON KEYBOARD HANDWRITING

Abstract

"In this research paper, a study of user authentication by keyboard handwriting when entering a passphrase is performed. Based on the analysis and development of a mathematical function for the distribution of ""own"" and ""foreign"" areas, a module for filtering the author's input was created. To authenticate a user by keyboard handwriting when entering a passphrase, it is necessary to recognize the speed and dynamics of input (gaps between keystrokes and their retention). The time intervals between keystrokes and the period of keystroke hold allow us to characterize the user's handwriting on the keyboard quite unambiguously, which is confirmed by a number of experiments conducted during the study of user authentication features. In addition, the authentication method based on keyboard handwriting can be used to protect against fraudsters trying to gain unauthorized access to the system and for remote authentication when users are at a distance from the server. The results of the study and the developed software module can be used to create a hybrid access control system that combines two authentication methods - password and biometric. Thus, the final control system will provide an enhanced authentication procedure compared to classical password authentication. The keyboard handwriting authentication method has great potential for use in the field of cybersecurity and can be used as an effective tool to ensure system security. "
