Abstract

"sensor com assinatura digital de dados relacionados ao sensor". um sensor tem códigos úteis para um monitor que pode ser autenticado como preciso. o sensor produz um sinal que corresponde a uma característica fisiológica mensurada e fornece códigos que podem ser assegurados de estarem precisos e autênticos quando utilizados por um monitor. uma memória associada ao sensor armazena tanto os dados relacionados ao sensor como uma assinatura digital. a assinatura digital autentica a qualidade do código ao assegurar que ele foi gerado por uma entidade que tem predeterminados controles de qualidade, e assegura que o código é preciso.
