Kopernica uses information reflected in people’s faces to understand emotional and behavioral data, but the faces are not recorded, recorded or stored. That is, with the so-called “faceless” technique, which does not take any images, it only takes exclusively numerical data derived from micro-expressions that it correlates with possible emotional reactions. These numerical data are aggregated with many other data from different subjects, losing any kind of individual reference. It also does not handle any personal information of the people interacting with the Kopernica system. Therefore the security of personal data is completely safeguarded.
