Abstract

"SISTEMA DE ADMINISTRAçãO DE DIREITOS DIGITAIS". Se descreve uma infra-estrutura de licenciamento público (PLI) para um sistema de administração de direitos digitais (DRM). Em uma implementação, um método inclui a geração de uma licença formal para conteúdo. A licença formal inclui uma chave de descodificação para descodificação de conteúdo e regras de acesso para acesso de conteúdo. Uma pluralidade de autoridades de licença se configura para prover uma pluralidade de licenças parciais. A pluralidade de licenças parciais pode ser combinada para constituir a licença formal. Cada autoridade de licença provê uma licença parcial respectiva.
