A new biometric can be created with a different biometric engine, rendering the previous biometric useless, as each biometric model generates an entirely different map.<\/p><p>The image below illustrates the map that a different biometric engine would have learned. From the training &#8220;recipe&#8221; of one biometric engine, an infinite number of different biometric engines can be trained with the same level of accuracy.

Therefore, the TSNE algorithm will have to generate a representation that looks for similarities between different people.<\/p><p>The visualization below shows how all images are grouped into a single sphere. This behavior is ideal because it implies that the model has no relevant gender or race biases. If it did, instead of a single sphere, we would be looking at several: e.g. one sphere for men and another for women.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-b2f7576 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"b2f7576\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-72aa813\" data-id=\"72aa813\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-b9997af elementor-widget elementor-widget-image\" data-id=\"b9997af\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"456\" height=\"421\" src=\"https:\/\/veridas.com\/wp-content\/uploads\/2022\/06\/biometria-facial-veridas_6.gif\" class=\"attachment-large size-large wp-image-36003\" alt=\"\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-82be635 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"82be635\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-304a264\" data-id=\"304a264\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-c315c0e elementor-widget elementor-widget-text-editor\" data-id=\"c315c0e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Finally, if we look for the closest images we can see how they are people of different race or gender in many occasions, which corroborates the absence of significant biases of the biometric model.
