Abstract
método para autenticar uma marca magneticamente induzida com um dispositivo portátil. começar aqui a invenção se refere a um método de autenticação de uma marca magneticamente induzida aplicada em um substrato incluindo partículas de pigmento magnético ou magnetizável em formato de plaqueta parcialmente reflexivas magneticamente orientadas, com um dispositivo portátil equipado com uma fonte de luz operável para entregar luz visível, um imageador, um processador e uma memória, em que o método compreende calcular, com o processador, uma intensidade média correspondente i da luz refletida pelas partículas de pigmento magnético ou magnetizável em formato de plaqueta parcialmente reflexivas e coletadas pelo imageador em ângulo de visualização correspondente ¿, armazenar as intensidades médias calculadas da luz refletida e ângulos de visualização correspondentes para obter uma curva de intensidade de luz refletida i(¿), comparar a curva de intensidade de luz refletida armazenada i(¿) com uma curva de intensidade de luz refletida de referência armazenada iref(¿) para a dita marca magneticamente induzida e determinar se a marca magneticamente induzida é verdadeira com base em um resultado da comparação.
