Abstract

"PORTADOR DE GRAVAçãO PARA ARMAZENAR UM TRABALHO DIGITAL, MéTODO PARA GRAVAR UM TRABALHO DIGITAL EM UM PORTADOR DE GRAVAçãO, E, DISPOSITIVOS PARA GRAVAR UM TRABALHO DIGITAL EM UM PORTADOR DE GRAVAçãO, E PARA LER O PORTADOR DE GRAVAçãO". A presente invenção relaciona-se a um portador de gravação para armazenar um trabalho digital (DW). O portador de gravação (10) inclui informação de acesso (KLT) para ganhar acesso ao trabalho digital e um canal secundário (HC), no qual informação de canal secundário (KLK) é armazenada que é usada para criptografar, descriptografar ou verificar a informação de acesso (KLT). Para prevenir, impedir ou desencorajar fraude com a informação de acesso (KLT), o canal secundário (HC) é armazenado, no portador de gravação substancialmente no mesmo local físico como a informação de acesso (KLT). Em uma concretização preferida, a informação de canal secundário KLK) é mudada quando a informação de acesso (KLT) mudou. Isto realiza um portador de gravação para o qual um ataque de reprodução é prevenido. A invenção ademais relaciona-se a um método para gravar um trabalho digital em um portador de gravação, um dispositivo para gravar e um dispositivo para ler.
