Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for licensing a digital work, a method thereof, and a program thereof for protecting the rights of a digital work. Specifically, a user who intends to use digital works scattered on the Internet can obtain permission to use the work without searching for the copyright holder of the work to be used by himself / herself. At the same time, the copyright holder of the copyrighted material can save the labor of the copyright holder himself / herself in the license processing by pre-registering the information necessary for the permission in the agency center. The present invention relates to a technology capable of performing a license processing for a large number of unspecified works on a personal computer via a network.

[0002]

2. Description of the Related Art With the recent development of the Internet, data such as images and music are often posted on homepages. The user can download such data with the browser of the terminal. Much of this data is copyrighted, the terms of use are posted on the same website, and the user who wishes to use the data may be permitted to use the website. Note that copyright related organizations may perform such procedures on their behalf. The user is
By requesting a copyright-related organization to research the copyright holder's information and obtain a license, the copyrighted material can be reused for exhibitions and publications.

[0003]

However, in the past, even if a request is made to a copyright-related organization for an investigation or a license, the procedure is complicated and takes a long time. There are many cases where copyrighted works are diverted without permission without making a request to a group. As a result, the copyright protection of copyrighted works is not sufficiently achieved.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to use digital copyrighted works capable of protecting the rights of digital copyrighted works scattered over networks such as the Internet. To provide a license system, its method, and its program.

[0005]

FIG. 14 and FIG. 15 are diagrams showing the flow of processing for permission to use a copyrighted work. Note that the process of licensing the copyrighted work is started by a request from the user terminal 4 used by a registered user, but it is immediately started by a request after the display of the registration result confirmation screen (413) described above. You can also

First, when the authentication process is completed between the user terminal 4 and the authentication center 1 (501 to 506), the authentication center 1 notifies the copyright management center 2 of the authentication process confirmation (507).

Upon receiving the authentication processing completion notice (508), the copyright management center 2 requests the user terminal 4 to send the copyrighted work selected on the website 6 (5).
09).

The user terminal 4 receives and displays the sending request (510, 511), and the copyrighted material selected on the website 6 is transferred to the copyright management center 2 via the communication network 7.
(512, 513).

The copyright management center 2 receives the copyrighted work (514), reads the electronic watermark of the copyrighted work using a watermark reading tool (program) (515), and extracts the copyright information identification ID (516). ).

On the other hand, the authentication center 1 sends the user ID to the usage permission processing proxy center 3 (517). The authorization processing agency center 3 receives the user ID from the authentication center 1.
The copyright information identification ID is received from the copyright management center 2 (518), and the license agreement information matching the copyright information identification ID is extracted from the copyright license agreement database 31 (519). The extracted license agreement is presented to the terminal 4 (520). The user terminal 4 is
The license agreement presentation for the corresponding work is received (52
1), accepting the license conditions (52)
2).

After concluding the license agreement contents (523), the license agreement processing center 3 stores the license agreement contents in the license agreement contents database 32 (524). Simultaneously with the conclusion of the license processing, the license certificate including the license ID as an electronic signature is issued to the user terminal 4 (525). In addition, the copyright holder terminal 5 is notified of the content of the license (527).

The user terminal 4 receives the license certificate (526), and the copyright holder terminal 5 receives the license content (528).

FIG. 16 is a diagram showing an output example of the usage license certificate. As shown in FIG. 16, the license certificate includes
License ID, certificate issuing authority ID, copyright information identification I
D, copyright holder ID, copyright holder name, user ID, user name, permission range, usage method, purpose of use, usage expiration date, modification permission range, copy permission, usage fee, payment method, etc. ing.

That is, by managing copyrighted works scattered on a network such as the Internet and systematizing the usage permission processing, the rights and the usage status are clarified, and the copyright holder and the user can feel secure about digital works. It becomes possible to create and use things.

By the way, in the present invention, the charging process to the user may be performed. That is, the charge amount is obtained by multiplying the number of times of issuance of the license certificate by a predetermined unit amount, and the user information database 1 is set as one of the user information.
It is stored in 1. Then, for example, the billing amounts may be summed up for each month and processed so as to be deducted from the user's financial institution account. Moreover, you may perform the process which transfers a part of the withdrawn money to the financial institution account of the copyright holder.

The present invention is one of the methods for a copyright user to clarify an ambiguous right relationship without paying attention to the conventional complicated license processing of a copyrighted work. It can be expected that the distribution of high-quality digital works will be promoted and that it will contribute to the development of the information society.

The program for executing the above-described processing is recorded on a computer-readable recording medium such as a semiconductor memory, a magnetic disk, an optical disk, a magneto-optical disk, a magnetic tape, or via a communication network such as the Internet. It can be transmitted and widely distributed.
