cze	Stanovení hranice míry nepodobnosti v biometrické autentizaci	Článek se zabývá stanovením vhodné hranice míry nepodobnostiv biometrické autentizaci. Pro tento účel jsou analyzovány zejména možností nebayesovských úloh statistického rozhodování, protože bayesovský přístup v tomto případě použít nelze.

eng	Determination of Suitable Boundary in Biometric Authentication	This article is focused on a problem of setting suitable boundary in the biometric authentication. The biometric authentication is somewhat different from the other kinds of authentication. While password matches relevant template which are saved in database or password does not match, biometric characteristics are somewhat stochastic. It means biometric characteristics (e.g. voice) can never absolutely match to their relevant templates. For this reason the system analyst has to set the strictness of similarity between submitted biometric characteristics and relevant templates. In this case the subject is considered as a valid user, not as an impostor. Non-Bayes tasks of a statistical decision seem to be a quite suitable tool for solving this problem.
