摘要：
Embedded proprietary data, which is configured by embedding decoding key data for decoding encoded contents into proprietary data that is a subject of ownership, is recorded on a recording medium. Since the decoding key data is embedded into the proprietary data, it is difficult to separate and take out the decoding key data from the proprietary data. When copying or the like including the proprietary data is performed, it becomes possible to legally pursue a copy or the like of the proprietary data.
