Abstract

"MéTODO PARA GERENCIAMENTO DE INFORMAçãO DE PROTEçãO DE CóPIA DE MEIO DE GRAVAçãO". Um método para gerenciamento de informação de proteção de cópia de um meio de gravação é representado. A informação de proteção de cópia para decodificar dados A/V codificados e gravados em uma área de dados de um disco óptico, tal como um CD, um DVD ou um BD, é gravada em uma trava de senha no disco óptico. Um primeiro valor de senha para ler a informação de proteção de cópia é gravado em uma área específica do disco óptico, e um segundo valor de senha para ler a informação de proteção de cópia é gerenciado em uma unidade de disco óptico ou em uma aplicação. Para reproduzir os dados A/V no disco óptico, a informação de proteção de cópia gravada na trava de senha é lida e decodificada por uma combinação de um código escondido (tendo o primeiro valor de senha) gravado no disco óptico e uma senha de unidade ou de aplicação (tendo o segundo valor de senha) gerenciada na unidade de disco óptico ou aplicação. Isso significantemente aumenta a segurança da informação de proteção de cópia.
