Abstract

The present disclosure comprises a method for obtaining a model for a spectrometer or a spectroscope, wherein a model comprises a relationship between a spectrum of a gas mixture or gas and parameters of the gas mixture or gas, in particular the composition and/or concentrations of individual components of the gas mixture, including: - acquiring a reference spectrum of a predetermined gas or gas mixture by means of the spectrometer or spectroscope and parameters of the predetermined gas or gas mixture, in particular the composition and/or concentrations of concentrations of the individual components of the predetermined gas mixture; encrypting the spectrum and/or the parameters by means of a homomorphic encryption method; and analyzing the spectrum and parameters without decoding the spectrum, or parameters.
