The approach realized in the developed mathematical model of the multimodal user authentication system, obtaining an estimate of the conditional probabilities of the Bayesian network of trust based on the use of non-numerical expert, inaccurate and incomplete information about the user's biometric parameters is considered. The averaged estimates of probabilistic parameters and the standard deviations corresponding to them are obtained, which make it possible to solve the problem of estimating the probability of legitimacy of the user working with the system.
