Abstract

trata-se de um dispositivo que recebe um padrão de privacidade de um nó de rede. o dispositivo forma uma máscara de privacidade temporária com o uso de um valor variável no tempo e do padrão de privacidade e criptografa um valor de código com o uso da máscara de privacidade temporária. o dispositivo transmite o valor de código criptografado. um dispositivo de recepção recebe um valor de código criptografado e forma uma máscara de privacidade temporária com o uso de um valor variável no tempo e de um padrão de privacidade que o mesmo também recebeu de um nó de rede. em seguida, o dispositivo de recepção pode decriptografar o valor de código com o uso da máscara de privacidade temporária. o código pode identificar um indivíduo ou um grupo e pode ser protegido com o uso de um padrão de privacidade que é específico ao indivíduo ou ao grupo.
