Abstract

uma matriz de sensor para leitura de uma puf magnética. um dispositivo de matriz de sensor magnético é descrito que é construído com múltiplo único sensor matriz, cortado fora de um wafer como um grupo e empacotado em um pacote de nível de wafer (wlp). o dispositivo compreende uma matriz de sensores magnéticos de múltiplos eixos que pode medir o campo magnético multidimensional de uma região bidimensional de tamanho arbitrário com alta resolução espacial, distância de detecção reduzida, maior rendimento de medição, tolerância ao movimento, medição de temperatura aprimorada, e rendimento aprimorado quando colocado em um cartão de circuito compreende parte de um sistema de autenticação incluindo uma função física não clonável (puf), um substrato, uma pluralidade de partículas magnetizadas dispersas aleatoriamente no substrato, e um leitor de puf construído usando um ou mais dos dispositivos de matrizes de sensores magnéticos em que o leitor de puf mede o campo magnético em vários locais próximos às partículas magnetizadas. os dados do campo magnético medidos podem ser comparados a dados previamente registrados para avaliar a autenticidade.
