Contents processing method, contents processing system, recording device, execution device, central device, and computer memory product

A contents processing system comprising:

• a recording device for recording contents on a medium;
• and
• an execution device for reproducing, displaying or executing the contents recorded on the medium,
• wherein the recording device includes a processor capable of performing the following operations:
• storing contents in advance in conjunction with first specifying information for specifying the contents;
• accepting first specifying information;
• extracting the stored contents, based on the accepted first specifying information;
• reading an identifier given uniquely to the medium;
• encrypting the extracted contents, based on the read identifier;
• recording the encrypted contents on the medium;
• accepting a limiting condition for reproducing, displaying or executing the contents;
• and
• recording the accepted limiting condition on the medium,
• wherein the execution device includes a processor capable of performing the following operations:
• reading the identifier of the medium;
• decrypting the contents recorded on the medium in an encrypted form, based on the read identifier;
• and
• reproducing, displaying or executing the decrypted contents under the limiting condition recorded on the medium.
