The article is devoted to solving the problem of multidimensional biometric authentication on the base of combination of several biometric indicators -fingerprints, facial geometry and voice. The indicators applied in the proposed system are the most accessible source of biometric credentials as well as provides for the compliance to such requirements to identification and authentication systems as noninvasive data acquisition for the analysis, relative inexpensiveness and compactness / portability of the system under development. The proposed approach implemented in the hardware and software suite described in the work has an advantage over the existing unifactorial biometric authentication approaches by such indicators as FRR and FAR and is also easy in use. The result of the proposed individual multidimensional biometric authentication system is the increase in overall reliability compared to the separate use of the current methods as well as a relatively small increase in the system response delivery time (from data input in the system to namely identification).
