Abstract
SISTEMA DE LEITOR DE ÁREA DE CAMPO MAGNÉTICO MULTIDIRECIONAL COM RECURSOS. Trata-se de um sistema para uso em processos de autenticação compreendendo uma função não clonável física (PUF), um substrato, uma pluralidade de partículas magnetizadas aleatoriamente dispersadas no substrato, um leitor de PUF construído usando múltiplos chips de magnetômetro discretos que têm sensores de campo magnético. Os dados de campo magnético medido podem ser comparados a dados anteriormente registrados para avaliar autenticidade.FEATURED MULTIDIRECTIONAL MAGNETIC FIELD AREA READER SYSTEM. It is a system for use in authentication processes comprising a physical non-clonable function (PUF), a substrate, a plurality of randomly dispersed magnetized particles on the substrate, a PUF reader constructed using multiple discrete magnetometer chips that have magnetic field. The measured magnetic field data can be compared to previously recorded data to assess authenticity.
