Abstract

Изобретение относится к способу сохранения данных на записываемом носителе данных, к соответствующему носителю данных, к соответствующему записывающему устройству и к соответствующему воспроизводящему устройству. Меры защиты от копирования требуют, чтобы на носителе данных с возможностью перезаписи хранились некоторые данные, которые невозможно видоизменить или стереть с помощью конечной потребительской продукции. Практическая проблема заключается в хранении больших количеств этих данных в участке фиксированных данных. Обычно ёмкость ограничивается несколькими битами. При этом объём данных для защиты от копирования, который необходимо хранить, может намного превышать ёмкость памяти, имеющейся в участке фиксированных данных с доступом только по чтению. Изобретение предлагает записывать данные защиты от копирования как системные данные в участке (4) записываемых данных, например как часть форматирования носителя (1). Криптографическую итоговую информацию вычисляют и также хранят в участке (32) записываемых данных или в участке (2) фиксированных данных, в результате чего обеспечивают криптографическую взаимосвязь между участком (2) фиксированных данных и участком (3) системных данных. Воспроизводящее устройство будет принимать только носитель данных с действительной комбинацией данных защиты от копирования и фиксированных данных.Отчет о международном поиске был опубликован 2002.03.21.
