SYSTEM DEVELOPMENT FOR IDENTIFICATION AND CONFIRMATION OF ACCESS LEGITIMACY BASED ON BIOMETRIC AUTHENTICATION DYNAMIC METHODS
Biometric methods are based on determining a person's identity based on characteristics that are unique to them. The article considers the characteristics of the keyboard dash as a dynamic biometric characteristic of a person. The analysis and selection of characteristics necessary for identification is carried out. Algorithm for the process of forming a reference sample of keyboard handwriting based on fixing time parameters. Classical statistical approaches to identifying users by keyboard handwriting are considered. It was found that approaches for collecting and analyzing parameters are also suitable for forming keyboard handwriting on mobile devices. It is noted that the use of keyboard handwriting as the only authentication factor on a mobile device does not yet achieve sufficient accuracy, but it is quite acceptable as an additional authentication factor. To solve the identification problem, it is proposed to use a client-server application, its characteristics are given, test tests are carried out and the results of the results are analyzed.
