Abstract

UM DISPOSITIVO DE VARA PORTÁTIL E MÉTODO PARA VERIFICAR OS DADOS DE ASSINATURA FÍSICA DE UMA FUNÇÃO FÍSICA NÃO CLONÁVEL AO LONGO DE UM PERCURSO ARBITRÁRIO. Objetos de função física não clonável única são criados pela moldagem de partículas pré magnetizadas ou pós-magnetizadas em uma resina. As partículas formam uma "impressão digital" física única com base no tamanho de partícula aleatório, posição, rotação polar, nível de magnetização, densidade de partícula, etc. Esta invenção aborda dispositivos para medir com precisão a impressão digital física de uma PUF, especificamente incluindo os componentes X, Y, & Z do campo magnético em pontos discretos suficientes na PUF para permitir um reconhecimento confiável da identificação. Uma vara portátil é descrita para medir o campo magnético ao longo de um percurso arbitrário.
