The article discusses the features of biometric voice identification under the condition of quiet pronunciation of password phrases. Biometric voice identification differs significantly from standard identification systems and access control systems using symbolic passwords and keys. Biometric voice identification is based on unique and individual characteristics of identity and virtually eliminates the possibility of unauthorized actions associated with loss, theft or transfer of the password to third parties. The widespread use of biometric voice identification systems entails increased interest on the part of malefactors. The most frequent are attacks using previously used biometric features, for example, audio recording of a passphrase. To minimize the attacks described above, a biometric voice identification method, based on the whitening filter method, adapted to the quiet pronunciation of passphrases has been proposed. Described is the software implementation of the proposed method - "Information system for identifying speakers by voice", which allows biometric identification by voice, provided that password phrases are quietly uttered to counteract the leakage of speech information through acoustic channels.
