Abstract

Ряд элементов данных выбирают для включения в набор данных, чтобы препятствовать передаче полного набора по линии связи с ограниченной пропускной способностью, такой как Интернет. Каждая часть набора данных связана с целостностью набора данных так, чтобы можно было различить части наборов данных, которые распространяются независимо. В случае аудиозаписи, например, набор данных включает в себя целый альбом, отдельные песни в альбоме составляют части этого набора данных. Связывая каждую песню с альбомом, соответствующее устройство воспроизведения может быть настроено так, что отказывает в воспроизведении элементов в отсутствие полного набора данных. Таким образом, незаконное использование песни потребовало бы незаконного использования полного альбома. Несжатая цифровая запись полного объема занимает сотни мегабайт данных, и неосуществимость или непрактичность загрузки сотен мегабайт данных, как ожидается, обеспечат достаточное препятствие для воровства несжатого содержательного материала. В предпочтительном варианте осуществления "водяной знак" создается для каждого раздела посылаемых данных, который содержит "параметр целостности", связанный с набором данных. Параметр целостности представляет собой значение хеш-функции, которое основано на случайном числе, сохраненном в "водяных знаках" каждого раздела. При воспроизведении параметр целостности считывается и "водяные знаки" случайного набора разделов в пределах набора данных сравниваются с этим параметром целостности, чтобы гарантировать со статистической уверенностью, что целостность набора данных присутствует.A number of data elements are selected for inclusion in the data set in order to prevent the transfer of the complete set over a communication link with limited bandwidth, such as the Internet. Each part of the data set is related to the integrity of the data set so that parts of the data sets that are distributed independently can be distinguished. In the case of audio recording, for example, the data set includes an entire album; individual songs in the album form parts of this data set. By associating each song with an album, the corresponding playback device can be configured to refuse to play items in the absence of a complete set of data. Thus, illegal use of a song would require illegal use of a full album. Uncompressed digital recording of the full volume takes hundreds of megabytes of data, and the impossibility or impracticality of downloading hundreds of megabytes of data is expected to provide a sufficient obstacle to the theft of uncompressed content. In a preferred embodiment, a "watermark" is created for each section of the data being sent, which contains an "integrity parameter" associated with the data set. The integrity parameter is a hash value that is based on a random number stored in the watermarks of each section. During playback, the integrity parameter is read and the watermarks of a random collection of sections within the data set are compared with this integrity parameter to ensure with statistical certainty that the integrity of the data set is present.
