Abstract

A document management system includes a memory portion that stores an original document identifier and a first derived document identifier in association with a second apparatus identifier, the original document identifier being provided to an original document, the first derived document identifier being provided to a first derived document created when the original document is copied, printed, edited, or sent by a first apparatus, the second apparatus identifier being provided to a second apparatus that further copies, prints, edits, or sends the first derived document; and a search portion that searches for a distribution path of the original document with the use of the association of the original document identifier, the first derived document identifier, and the second apparatus identifier.

Claims

1. A distributed and decentralized document management system including a first copier, a second copier, and a third copier, the second copier comprising:

a creation portion that, in a case of copying an original document that includes an original document identifier and a first copier identifier that identifies the first copier that created the original document, creates a first derived document that includes a first derived document identifier and a second copier identifier that identifies the second copier, in the document management system, that creates the first derived document;

a transmission portion that transmits the original document identifier and the second copier identifier to the first copier that created the original document;

a receiving portion that receives the first derived document identifier and a third copier identifier that identifies the third copier, in the document management system, that further copies the first derived document;

a memory portion that stores the original document identifier, the first copier identifier, the first derived document identifier, and the third copier identifier in relation to each other;

a search portion that searches for a distribution path of the original document with the use of the association of the original document identifier, the first derived document identifier, and the third copier identifier; and

a notification portion that conveys at least one information in the memory portion to a search requester when a search is conducted by the search portion,

the copying, of the original document being performed by the second copier.

2. The distributed and decentralized document management system according to claim 1, wherein the at least one information is selected from the list including date and time when the original document is copied, an identifier of a person who copies the original document, and an operation type executed by the person who copies the original document, as an operation history.

3. The distributed and decentralized document management system according to claim 1, further comprising a display portion that displays a search result by the search portion.

4. A distributed and decentralized document management system comprising multiple copiers, each copier comprising:

a creation portion that, in a case of copying an original document that includes an original document identifier and a first copier identifier that identifies a first copier that created the original document, creates a first derived document that includes a first derived document identifier and a second copier identifier that identifies a second copier, in the document management system, that creates the first derived document;

a transmission portion that transmits the original document identifier and the second copier identifier to the first copier that created the original document;

a receiving portion that receives the first derived document identifier and a third copier identifier that identifies a third copier, in the document management system, that further copies the first derived document;

a memory portion that stores the original document identifier, the first copier identifier, the first derived document identifier, and the third copier identifier in relation to each other;

a search portion that searches for a distribution path of the original document with the use of the association of the original document identifier, the first derived document identifier, and the third copier identifier; and

a notification portion that conveys at least one information in the memory portion to a search requester when a search is conducted by the search portion,

the copying of the original document being performed by the second copier.

5. A distributed and decentralized document management method comprising:

creating, in a case of copying an original document that includes an original document identifier and a first copier identifier that identifies a first copier that created the original document, a first derived document that includes a first derived document identifier and a second copier identifier that identifies a second copier, in the document management system, that creates the first derived document;

transmitting the original document identifier and the second copier identifier to the first copier that created the original document;

receiving the first derived document identifier and a third copier identifier that identifies a third copier that further copies the first derived document;

storing the original document identifier, the first copier identifier, the first derived document identifier, and the third copier identifier in relation to each other;

searching for a distribution path of the original document with the use of the association of the original document identifier, the first derived document identifier, and the third copier identifier; and

conveying at least one information to a search requester when a search is conducted,

the copying of the original document being performed by the second copier.

6. A distributed and decentralized document management copier comprising:

a creation portion that, in a case of copying an original document that includes an original document identifier and a first copier identifier that identifies a first copier that created the original document, creates a first derived document that includes a first derived document identifier and a second copier identifier that identifies the document management copier that creates the first derived document;

a transmission portion that transmits the original document identifier and the second copier identifier to the first copier that created the original document;

a receiving portion that receives the first derived document identifier and a third copier identifier that identifies a third copier that further copies the first derived document;

a memory portion that stores the original document identifier, the first copier identifier, the first derived document identifier, and the third copier identifier in relation to each other;

a search portion that searches for a distribution path of the original document with the use of the association of the original document identifier, the first derived document identifier, and the third copier identifier; and

a notification portion that conveys at least one information in the memory portion to a search requester when a search is conducted by the search portion,

the copying, of the original document being performed by the second copier.
