In recent years, the digitization of information is increasing. Since digitized information (hereinafter referred to as digital content) is relatively easy to use and does not deteriorate over time, information such as audio and image data is becoming more and more digitized.

But when digital content is copied, the copy becomes exactly the same as the original. This causes unauthorized activities such as illegal copying and alteration of copyright information.

In order to discourage the unauthorized use of digital content, a method has been devised in which digital content is accompanied by management information indicating a condition for the use of digital content and the use of digital content is prohibited if any one of these conditions is not satisfied.

There is also a way to prevent two devices from authenticating with each other (i.e. mutual authentication) before any use of the digital content and to prevent any unauthorized device from using the digital content to prevent the invalid device from using the digital content.

In addition, there is a method in which a storage medium such as a memory card is given a unique number (hereinafter referred to as a "card ID") so that each storage medium stores only digital content encrypted using its own card ID. Even if digital content encrypted in this way is copied to another memory card, the copy of the encrypted digital content cannot be decrypted by the card ID of the latter memory card, and the unauthorized copying will end in failure.
