Abstract

MéTODO E APARELHO DE PROTEGER DADOS COMPARTILHADOS, MéTODO E APARELHO DE REPRODUZIR MEIO DE GRAVAçãO UTILIZANDO UMA ARMAZENAGEM LOCAL. São descritos um método e aparelho para proteger dados compartilhados e método e aparelho para reproduzir dados a partir de um meio de gravação utilizando uma armazenagem local. A presente invenção inclui transferir os dados compartilhados associados a um meio de gravação para uma armazenagem local e permitir que uma aplicação tendo informação válida de acesso para os dados compartilhados, acesse os dados compartilhados. A presente invenção inclui transferir dados compartilhados criptografados associados ao meio de gravação para a armazenagem local, construir um pacote virtual incluindo os dados compartilhados pela ligação de dados na armazenagem local com dados no meio de gravação, decriptografar os dados compartilhados utilizando o pacote virtual, e reproduzir os dados compartilhados decriptografados. Por conseguinte, os conteúdos fornecidos por um provedor de conteúdo autêntico e os conteúdos não transmutados podem ser reproduzidos, pelo que os dados compartilhados podem ser protegidos. E os dados compartilhados podem ser protegidos contra uma função maliciosa causada por uma aplicação não autorizada.
