Abstract

Patente de Invenção: <B>"MODELO DE SEGURANçA PARA APLICAçõES DE TELEVISãO INTERATIVA"<D>. Um sistema e um método implementados em um sistema de televisão interativa para restringir ou controlar os direitos de acesso de aplicações de televisão interativa e de carrosséis. O sistema transmite módulos de uma estação de transmissão para uma pluralidade de estações de recepção, as quais executam as aplicações que contêm os módulos. Em uma modalidade a aplicação utilizada uma credencial que consiste em um número de identificação do produtor (ID) e uma ID de aplicação para cada uma das aplicações do concedente e do concedido, uma data vencimento, um conjunto de dados de permissão, um certificado do produtor e uma assinatura. Uma aplicação que solicita acesso e um carrossel que concede o acesso podem ser identificados pelas respectivas IDs do produtor e da aplicação. A credencial utiliza uma cifragem de chave pública para garantir a integridade de credencial. As IDs do produtor e da aplicação podem ser substituídas por cartas aleatórias de modo que os direitos possam ser concedidos para um grupo de produtores ou de aplicações.
