Abstract

When new music content is generated on the basis of replication of original music content, additional information including information indicating that the generated new music content is based on replication and replication source information identifying a replicated-from source of the replicated content is generated and added to the new music content based on the replication. When the new (i.e., replicated) music content is to be used, a search is made for original music content on the basis of information identifying a replicated-from source and use of the new (replicated) music content is permitted only when the c original music content has been successfully found. Such arrangements reliably allow the replicated content to be used by a given person only when the person possesses the original music content.

Claims

1. A music-content using apparatus comprising:

a communication interface that acquires music content including additional information added thereto, the additional information including information indicating that the music content is based on replication and replication source information identifying a replicated-from source at which the music content is located;

a programmed processor that is programmed to perform;

a search step of searching original music content on the basis of the source information included in the additional information added to the music content acquired via said communication interface; and

a use step of permitting the use of the acquired music content only when the original music content has been successfully found by said search step.

2. A music-content using apparatus as claimed in claim 1 wherein the music content acquired via said communication interface includes a management data region and substance data region, and the additional information is stored in the management data region.

3. A music-content using apparatus as claimed in claim 2 wherein, in the substance data region, there are included substance data of the acquired music content that comprise a replication of at least some of substance data of the original music content.

4. A music-content using apparatus as claimed in claim 2 wherein, in the substance data region, there are included substance data of the acquired music content obtained by changing at least some of substance data of the original music content.

5. A music-content using apparatus as claimed in claim 4 wherein said programmed processor is further programmed to perform the step of acquiring the at least some of substance data from the original music content found by said search step, if the use of the acquired music content is permitted and if the at least some of substance data of the original music content are not included in the substance data region of the acquired music content.

6. A music-content using apparatus as claimed in claim 1, further comprising:

a storage medium that stores music content;

wherein said programmed processor is further programmed to perform an encryption step of encrypting, with medium information specific to said storage medium, music content to be stored in said storage medium and then storing the encrypted music content in said storage medium.

7. A computer-readable medium encoded with a computer program having a group of instructions for causing a computer to perform a music-content using method, said music-content using method comprising:

an acquisition step of acquiring music content including additional information added thereto, the additional information including information indicating that the music content is based on replication and replication source information identifying a replicated-from source at which the music content is located;

a search step of searching for original music content of the acquired music content on the basis of the replication source information included in the additional information added to the music content acquired via said acquisition step; and

a use step of permitting use of the acquired music content only when the original music content has been successfully found by said search step.
