Abstract

MéTODO PARA AUTORIZAR ACESSO A CONTEúDO POR UM DISPOSITIVO COLETOR, DISPOSITIVO FONTE ARRANJADO PARA AUTORIZAR ACESSO A CONTEúDO POR UM DISPOSITIVO COLETOR, E, PRODUTO DE PROGRAMA DE COMPUTADOR Um método de um dispositivo fonte (410) para autorizar acesso a conteúdo (425) por um dispositivo coletor (400) de acordo com direitos de uso, o conteúdo sendo armazenado em um meio de armazenagem (420) controlado pelo dispositivo fonte. O estado de revogação do dispositivo coletor é verificado usando a informação de revogação emitida mais recentemente que está disponível se os direitos de uso necessitam ser modificados como parte da autorização de acesso ao conteúdo, e usando informação de revogação associada ao conteúdo armazenado no meio de armazenagem, preferivelmente, diferentemente a informação de revogação armazenada no meio de armazenagem. A informação de revogação no meio de armazenagem, ou somente a parte relativa ao dispositivo coletor, é opcionalmente atualizada para a informação de revogação emitida mais recentemente, se os direitos de uso precisam ser modificados. Preferivelmente, isto é feito somente se o resultado da verificação é que o dispositivo coletor tenha sido revogado.
