ENABLING RECORDING AND COPYING DATA |
摘要 |
A data encryption key may be generated for encrypting data content. The data encryption key includes multiple portions. For example, the data encryption key may be generated by combining a drive seed and a media seed where the drive seed includes a value that is unique to the drive reading data content or a group of drives sharing the same drive seed. The media seed may include a value unique to the media from which data content may be read. The data encryption key thus generated may be unique to a combination of a specific drive or group of drives and a media or group of media. |
