Abstract

"MéTODO PARA PROVER CONFIANçA VERIFICáVEL AUTOMATICAMENTE EM UM PROCESSO DE RESOLUçãO DE CONTEúDO, E DISPOSITIVO (PDR)". Um método de prover confiança verificável automaticamente em um processo de resolução de conteúdo, no qual um PDR resolve um identificador de referência de conteúdo (CRID) identificando um item de conteúdo usando uma gravação de autoridade de resolução (RAR) para obter um localizador identificando uma localização onde o PDR pode obter o item de conteúdo. Preferivelmente, a medida compreende computar uma assinatura digital ao longo de pelo menos uma parte dos conteúdos do CRID, do localizador e/ou da RAR. O método pode também compreender criptografar pelo menos uma porção de dados do CRID, da RAR ou localizador. Direitos digitais necessários para acessar o item de conteúdo podem ser providos com o CRID, a RAR e o localizador.
