Method for automatic on-line updating of personal biometric data based on speech signal of the biometric system user

Abstract
The problem of “aging” of personal biometric data over time is considered. A method is proposed to overcome it by automatically updating the personal biometric data by using the speech signals of registered users obtained during latest requests for their identification and online service. The proposed method uses a scale-invariant indicator of the voice template quality. As a consequence, it is characterized by guaranteed reliability of the decisions made in the conditions of a wide speech signal dynamic range. It is shown that a guaranteed level of significance of decisions made by an observer is provided. The proposed method is implemented in a special software, which was used to experimentally estimate its effectiveness with real speech data. The obtained results are intended for use in the development of new and modernization of existing software and technologies for the personal biometric data automated quality control and updating.
