Abstract: A method for protecting a biometric template, comprising the steps of: retrieving an original vector (V) representing said biometric template, said vector comprising a plurality of original elements (v1, v2, . . . vi, . . . , vn); mapping at least some elements from said original vector to a protected vector (P) comprising a plurality of protected elements (p1, p2, . . . pi, . . . , pn−m+1), the mapping being based on multivariate polynomials defined by m user-specific coefficients (C) and exponents (E).

Abstract: An apparatus and a method for constructing a multilingual acoustic model, and a computer readable recording medium are provided. The method for constructing a multilingual acoustic model includes dividing an input feature into a common language portion and a distinctive language portion, acquiring a tandem feature by training the divided common language portion and distinctive language portion using a neural network to estimate and remove correlation between phonemes, dividing parameters of an initial acoustic model constructed using the tandem feature into common language parameters and distinctive language parameters, adapting the common language parameters using data of a training language, adapting the distinctive language parameters using data of a target language, and constructing an acoustic model for the target language using the adapted common language parameters and the adapted distinctive language parameters.

Abstract: An internet-connected server comprising a first module for authorizing a user to access the server for: setting up, on the server, a given configuration for conducting a computer-executable experiment, wherein the given configuration comprises at least an executable instruction and a parameter or input data; executing, on the server, the computer-executable experiment with the given configuration so to produce a numerical result; certifying, on the server, the numerical result so to produce a certified result; and generating, on the server, a certification identifier of the certified result. The internet-connected server further comprises a second module for authorizing a reviewer for: providing the server with the certification identifier; and requesting and/or accessing, on the server, the certified numerical result on the basis of the provided certification identifier.
