Music-content using apparatus capable of managing copying of music content, and program therefor
First Claim
1. A music-content using apparatus comprising:
- a communication interface for acquiring music content including first additional information, the acquired music content based on replication from first replicated-from content, the first additional information including;
first information indicating that the music content is based on replication andfirst replication source information identifying a first replicated-from source at which the first replicated-from content is located; and
a processor that is configured to perform;
first searching, through a memory system accessible by the music-content using apparatus, to find the first replicated-from content on the basis of the first replication source information included in the first additional information included by the music content acquired via said communication interface, said first searching based on the first replication source information identifying the first replicated-from source at which the first replicated-from content is located,wherein the first replicated-from content is original music content or not original music content,wherein, when the first replicated-from content is not original music content, the first replicated-from content includes second additional information, the first replicated-from content based on replication from second replicated-from content, the second additional information including;
second information indicating that the first replicated-from content is based on replication andsecond replication source information identifying a second replicated-from source at which the second replicated-from content is located,wherein, when the second additional information including the second replication source information is included by the first replicated-from content that has been found by the first searching, the processor is configured to perform;
second searching, through the memory system, to find the second replicated-from content on the basis of the second replication source information included in the second additional information included by the first replicated-from content,wherein the second replicated-from content is original music content or not original music content,wherein, when the second replicated-from content that has been found by the second searching is not original music content, the processor is configured to perform;
sequentially repeating said second searching one or more times to sequentially find one or more previous replicated-from content based on respective replication source information included in respective additional information included by the second and previous replicated-from content;
determining a determination indicating that the original music content has been successfully found by said first or second searching or the subsequently-repeated second searching; and
permitting use of the acquired music content based on said determination indicating that the original music content has been successfully found by said first or second searching or the subsequently-repeated second searching.

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.

7. A non-transitory computer-readable medium encoded with a computer program having a group of instructions for causing a computer of a music-content using apparatus to perform a music-content using method, said music-content using method comprising:
-
acquiring music content including first additional information, the acquired music content based on replication from first replicated-from content, the first additional information including; first information indicating that the music content is based on replication and first replication source information identifying a first replicated-from source at which the first replicated-from content is located; first searching, through a memory system accessible by the music-content using apparatus, to find the first replicated-from content on the basis of the first replication source information included in the first additional information included by the music content acquired via said acquiring, said first searching based on the first replication source information identifying the first replicated-from source at which the first replicated-from content is located, wherein the first replicated-from content is original music content or not original music content; wherein, when the first replicated-from content is not original music content, the first replicated-from content includes second additional information, the first replicated-from content based on replication from second replicated-from content, the second additional information including; second information indicating that the first replicated-from content is based on replication from second replicated-from content and second replication source information identifying a second replicated-from source at which the second replicated-from content is located, wherein, when the second additional information including the second replication source information is included by the first replicated-from content that has been found by the first searching, the music-content using method comprises; second searching, through the memory system, to find the second replicated-from content on the basis of the second replication source information included in the second additional information included by the first replicated-from content, wherein the second replicated-from content is original music content or not original music content, wherein, when the second replicated-from content that has been found by the second searching is not original music content, the music-content using method comprises; sequentially repeating said second searching one or more times to sequentially find one or more previous replicated-from content based on respective replication source information included in respective additional information included by the second and previous replicated-from content; determining a determination indicating that the original music content has been successfully found by said first or second searching or the subsequently-repeated second searching; and permitting use of the acquired music content based on said determination indicating that the original music content has been successfully found by said first or second searching or the subsequently-repeated second searching.
