FIELD: physics, computer engineering. ^ SUBSTANCE: invention relates to human biometric systems by individual characteristics of his voice for authorised access, for example, to an operating system, computer resources, bank account or physical access to rooms and in situations which require authorised access. The essence of the invention lies in the fact that the user verification method in systems of authorised access includes creation of a referral base of speaker data, creation of a user database, for user verification. The user enters their identifier and says the password from a random sequence of words from a vocabulary user database. After obtaining the sound signals of the pronounced password the probability of the pronounced password to the voice of the user is calculated and the decision to allow or deny access is taken. ^ EFFECT: reduction of the probability of mistaken admission of an impostor or rejection of a valid user using individual characteristics of the human voice in application to authorised access. ^ 9 dwg |
