Abstract

SISTEMA E MéTODO PARA O GERENCIAMENTO DE ACESSO A CONTEúDO PROTEGIDO POR APLICAçõES NãO-CONFIáVEIS é apresentado um dispositivo de comunicação e um método do mesmo para gerenciamento de acesso a conteúdo protegido. O dispositivo de comunicação compreende uma aplicação (302), um serviço de sistema de arquivos confiável (316), um agente confiável (318) e um renderizador de conteúdo confiável (320). A aplicação (302) solicita a execução de uma ação no conteúdo protegido (306). O serviço de sistema de arquivos confiável (316) identifica o conteúdo protegido (306) para a aplicação (302). O agente confiável (318) identifica os direitos associados ao conteúdo protegido (306) para a aplicação (302). O renderizador de conteúdo confiável (320) executa a ação em resposta à determinação de que a aplicação (302) é uma aplicação não-confiável com direitos suficientes para executar a ação.
