Abstract

An apparatus for generating copyright information for a secondarily processed content obtained by performing secondary processing on an original content, includes a secondary processed substance acquiring unit, a default license information generating unit, and a license information editing unit. The secondary processed substance acquiring unit acquires operation substances of the secondary processing performed on the original content. The default license information generating unit obtains rights expressions for the operation substances acquired by the secondary processed substance acquiring unit to generate default license information including the rights expressions as an initial value. The license information editing unit accepts selection of a desired rights expression by a user from the rights expressions of the default license information generated by the default license information generating unit to generate license information of the secondary processed content from the selected rights expression.

Claims

1. An apparatus for generating copyright information for a secondarily processed content obtained by performing secondary processing on an original content, comprising:

a secondary processed substance acquiring unit that acquires an adaptation right that determines a rights expression of a secondary processing operation for the original content, from license information of the original content, and that acquires operations designated by a user from the rights expression of secondary processing determined by the adaptation right acquired, the license information of the original content including a present-status use right that determines a rights expression of an operation for the original content, the adaptation right, a secondary processing present-status use right that determines a rights expression of an operation for the secondarily processed content, and a secondary processing adaptation right that determines a rights expression of a secondary processing operation for the secondarily processed content;

a default license information generating unit that obtains the secondary processing present-status use right and the secondary processing adaptation right for the operation acquired by the secondary processed substance acquiring unit, and generates default license information of the secondarily processed content that includes the present-status use right including a condition equal to a condition included in the obtained secondary processing present-status use right, the adaptation right including a condition equal to a condition included in the obtained secondary processing adaptation right, the secondary processing present-status use right including a condition equal to a condition included in the obtained secondary processing present-status use right, and the secondary processing adaptation right including a condition equal to a condition included in the obtained secondary processing adaptation right; and

a license information editing unit that accepts selection of a desired rights expression by a user from the rights expressions of the default license information generated by the default license information generating unit to generate license information of the secondarily processed content from the selected rights expression.

2. The apparatus according to claim 1, further comprising:

a content processing unit that performs secondary processing on the original content; and

an operation substance deciding unit that decides an operation of secondary processing performed on the original content based on operation information representing a series of operations of the secondary processing for the original content, wherein

the secondary processed substance acquiring unit acquires an operation designated by a user from the operation decided by the operation substance deciding unit.

3. The apparatus according to claim 1, further comprising:

a dictionary storage unit that stores a license information dictionary that has operations for a content that is designated as the rights expression in a hierarchical structure, wherein

the secondary processing substance acquiring unit displays the rights expression of a secondary processing determined by the adaptation right acquired in the hierarchical structure in the license information dictionary, and acquires the operation of the secondary processing designated by a user from the displayed rights expression.

4. The apparatus according to claim 1, further comprising:

a license information deciding unit that decides whether a condition included in the present-status use right and a condition included in the adaptation right of the license information of the secondarily processed content generated by the license information editing unit include a condition included in the secondary processing present-status use right and a condition included in the secondary processing adaptation right of the license information of the secondarily processed content generated by the license information editing unit, wherein

the license information editing unit, when determined by the license information deciding unit that the condition included in the present-status use right and the condition included in the adaptation right of the license information of the secondarily processed content do not include the condition included in the secondary processing present-status use right and the condition included in the secondary processing adaptation right of the license information of the secondarily processed content generated by the license information editing unit, accepts a selection of a desired rights expression from the permission contents of the default license information again to generate the license information of the secondarily processed content from the selected rights expression.

5. The apparatus according to claim 4, further comprising:

a permission verification rule storing unit that stores permission verification rule information in which a mismatched combination between the rights expressions is determined, wherein

the license information deciding unit further decides whether combinations between the rights expressions of the present-status use right, the adaptation right, the secondary processing present-status use right, and the secondary processing adaptation right in the license information of the secondarily processed content generated by the license information editing unit include a mismatched combination determined by the permission verification rule information, and

the license information editing unit, when the license information deciding unit decides that the combinations include the mismatched combination determined by the permission verification rule information, further accepts selection of a desired rights expression from the rights expressions of the default license information again to generate the license information of the secondarily processed content from the selected rights expression.
