Анализ задач, связанных с голосовой аутентификацией пользователей в вычислительных сетях

Abstract

The relevance of biometric authentication systems in computer networks is stated. The object of the study is voice authentication procedures. The research methods are analysis, synthesis, simulation, analysis of results and development of practical recommendations. The problems of temporal signal sampling in the voice channel, as well as noise suppression, allowing more efficient problem solving are considered. The requirements for sampling signal frequency within channel frequency are obtained during model experiment. The results of interfering signal suppression for voice message logging area are given. The main directions of continued researches connected with improvement of voice signal logging systems including compact devices (mobile gadgets) are determined.
