Feasibility study of a multimodal biometric authentication solution based on pointer dynamics and skin conductivity

Autor: Sá, Vítor J., Magalhães, Sérgio T., Santos, Henrique Dinis dos

Due to the constant need to improve authentication systems, since they are constantly emerging new forms of intrusion, based on the current state of knowledge, we intend to study the acceptance of a recognition system based on the combination of two
