We built a m ulti-biometric authentication of faces and voices by studying combinations of scores by simple methods are: the average, product, minimum, maximum, median and weighted sum. And the fuzzy measures: fuzzy integral Choquet and Sugeno. Another important issue addressed in this work is the normalization of scores is necessary before the combination of scores, for that we are trying to study at this stage three methods of normalization of scores are: Z-Score, quadratic-linear-quadratic (QLQ) and double sigmoid function.
