Leitor biométrico criptografado

Abstract

In the biometric market, several technologies have been presented to guarantee the identity of users when accessing sensitive information. With a significant increase in identity fraud attempts, resulting in substantial financial losses. Companies and institutions face the challenge of ensuring the authenticity of users. Aiming at the search for alternatives for the Brazilian market, this work aims to develop a prototype of an encrypted biometric device capable of collecting, storing and processing fingerprints in an encrypted form with protection of the type tamper-proof in its housing, using a plate development and a commercially available biometric collection device. For the development of the project, a review is carried out on biometric storage technologies and international standards, communication standards between electronic components, symmetric key cryptography and the Linux operating system. As a result, a functional device was obtained with an average processing time of a fingerprint in a base of 100 fingerprints of 4.29s and a false positive rate of 4%.
