Abstract

Распространение цифровой информации, в частности аудиоданных, контролируется следующим образом. Осуществляется распространение носителя информации (11), подобного компакт-диску (КД), который имеет, по меньшей мере, часть цифровой информации, зашифрованной с использованием ключа шифрования. Ключ дешифрирования, соответствующий ключу шифрования, также предоставляется пользователю, например, в зарезервированной области КД. Пользователь (32) воспроизводит аудиоданные в устройстве воспроизведения (31), которое дешифрирует информацию с использованием ключа. Однако, по меньшей мере, часть информации воспроизводится только после получения в устройстве воспроизведения персонализированного кода доступа РАС (40). РАС формируется в удаленном центре доступа (33), например, на сайте сети Интернет. База данных (34) соединена с центром, и память устройства воспроизведения хранит идентификатор устройства воспроизведения и секретный идентификатор устройства воспроизведения. Пользователь передает идентификатор устройства воспроизведения и идентификатор информации, идентифицирующий КД, в центр доступа, и центр доступа вычисляет РАС с использованием идентификатора и секретного ключа устройства воспроизведения. РАС передается в устройство воспроизведения, которое проверяет РАС с использованием своего собственного секретного ключа устройства воспроизведения и разрешает воспроизведение частей информации, защищенных с помощью РАС.Международная заявка была опубликована вместе с отчетом о международном поиске.
