PROBLEM TO BE SOLVED: To prevent distributed data, stored on a consumer's reproducing device by the on-line distribution of music content, etc., from illegally being copied. SOLUTION: When an OS is started, a copy command monitor part 14a resides in a data reproducing device 10 to monitor all events which possibly occur when the distributed data stored on the data reproducing device 10 are copied. Once the copy command monitor part 14a detects a command regarding copying, a management information check part 14b decides whether or not copying is inhibited according to the header part of object data of the copying of the command. When the copying in inhibited, an alarm part 14c requests the consumer to quit the copying. If the copying is not quit even a certain time later, a copying process quit part 14d accesses a command of the OS to quit the copying process. |
