摘要：
Even if an authorized second-generation copy of a production is illegally recorded on a recording medium, the copy cannot be reproduced. When a copy of a production is recorded on a disk, medium identification information recorded in the BCA on the disk is embedded as a watermark. When the copy is reproduced, the medium identification information recorded in the BCA is collated with the medium identification information embedded in the copy as an electronic watermark. Only when the both agree with each other, reproduction is performed.
