Abstract

codificação de região de função física não clonável. um objeto de função física não clonável (put) pode ser usado para codificar a geografia ou região na qual o dispositivo ao qual o put está conectado pode operar. são divulgadas duas maneiras possíveis de regionalizar um dispositivo usando um disco put; colocar o sensor magnético em um raio diferente, dependendo da região ou geografia pretendida para venda; e alterar a estrutura magnética do disco para codificar magneticamente a região nos dados do sensor.
