Abstract

"APARELHO, MéTODO E SISTEMA DE PROCESSAMENTO DE DADOS, MéTODOS DE COMUNICAçãO DE VALOR DE VERIFICAçãO DE DADOS, DE GERAçãO DE DADOS DE CONTEúDO E DE ATRIBUIçãO DE VALOR DE VERIFICAçãO DE DADOS DE CONTEúDO E MEIOS DE PROVISãO E DE SUPRIMENTO DE PROGRAMA". Um aparelho de processamento de dados e um método de processamento de dados averiguam que dados são válidos, impedem dados de chave de processamento de criptografia serem revelados, eliminam uso ilegal de dados de conteúdo, restringem a utilização de conteúdos, aplicam uma pluralidade de diferentes formatos de dados a conteúdos e executam eficientemente o processamento de reprodução de dados comprimidos. O processo de verificação de dados parciais é executada pelo cotejamento de dados parciais de integridade como valores de checagem para uma combinação de dados parciais de um conteúdo, e o processo de verificação da inteireza da combinação de dados parciais é executado pelo cotejamento de valores de checagem de integridade de verificação de valor de checagem de integridade parcial que verificam a combinação dos valores de checagem de integridade parciais. Chaves mestres para gerar chaves individuais necessárias para um processo como o de criptografia de dados são armazenadas na seção de armazenamento e chaves são geradas conforme necessário. Uma lista de dispositivos ilegais é armazenada na informação de cabeçalho de um conteúdo e sendo referida quando dados são usados. Chaves específicas a um aparelho de processamento de dados e chaves comuns são armazenadas, e as chaves são seletivamente usadas de acordo com a restrição de uso de conteúdo. Uma pluralidade de blocos de conteúdo são acopladas, e pelo menos uma parte dos blocos de conteúdo é aplicada a um processo de criptografia por uma chave de criptografia Kcon e, depois, dados de chave de criptografia que é a chave de criptografia Kcon criptografada por uma chave de criptografia Kdis, são armazenados na seção de cabeçalho. Dados de conteúdo são feitos de dados comprimidos e um programa de processamento de expansão, ou uma combinação de tipos programas de compressão, e o aparelho de reprodução podem determinar um programa de expansão aplicável a um conteúdo comprimido.
