Development of the System of Information Security with Use of a Biometric Authentication System on a Voice

In the modern world, there is an acute problem of information protection against unauthorized access to material and virtual resources. The aim of this work is the creation of software that implements the automated biometric user authentication by voice for further use in the system of information protection. In work present the overview of the commonly used techniques of the analysis of voice samples and signs that can be used as a sufficient voice features. The practical part of the work will be carried out using the method of analysis of a mixture of Gaussian distributions. As the features for creating a voice template will be used MFCC-coefficients. As the basis for a final decision will be used by the EM-algorithm. The result will be a prototype of automatic biometric user authentication by voice. The study used 14 illustrations, 11 source. Total size is 44 pages.
