Even in this case, the contract processing function 52 invalidates the previous license, issues a license request as a substitute license, and the license server 10 issues a license with a different license ID from the previous license.
- the list of available licenses or the list of expired licenses is managed by the insurance service server, and licenses are regenerated.
- the previous license has been invalidated, making the use of the lost ( ⁇ ) content impossible.
- the insurance service server redistributes the alternative content if the same content as the lost content cannot be redistributed, and the service provider of the distribution source responds to the redistribution of the content due to business suspension, etc. If not, redistribute alternatives from another service provider to the user. Therefore, the user is guaranteed the redistribution of the content and the license by joining the insurance. Users' rights are guaranteed even if the service provider has failed or has been shut down.
- the distribution service provider can remove the anxiety that users have for services when the content is lost.

- the user makes an initial license request to the license server 10, and the license server 10 sends the license request to the contract processing function 52 of the insurance service server 50.
- a back-end configuration that requests the addition of insurance can be adopted. In the case of this back-end configuration, the redelivery process is performed in the same way as in the front-end configuration.
- the guarantee conditions of the insurance contract (Fig. 6B) it was explained that the insurance policy including the insurance policy is issued to the user terminal and is attached to the license and sent to the user terminal.
- the license use determination function of the user terminal can extract the security condition information from the electronic receipt and store it.
- the insurance contract DB manages security conditions for each user, and sets the maximum number of relicenses for the same content as the maximum number of relicenses specified in the security conditions, as well as relicensing for all content purchased by the user.
- An upper limit may be set. For example, redistribution is permitted up to 10 times for all content purchased by the user, but redistribution of the same content is limited to 3 times.
- the redelivery history information may be modularized and exchanged between a plurality of insurance services to check for unauthorized users.
- the insurance service server 50 is provided with a function to detect failures in each of the distribution services 1 and 2, and detects the number of service failures in each distribution service, the time until restoration, and the like. Based on this, the security conditions (insurance premium) for each service provider may be changed.
- physical media such as mailing can be used in addition to electronic media.
- Physical media delivery can be used to send one or more of content, licenses, and insurance policies.
- the user After purchasing the license, the user mails the content to the user or downloads the content to the user. Later, the license can be mailed to the user, or the insurance policy can be mailed to the user after the user has purchased insurance.
- the insurance service server is used as the front end (Fig. 3)
- the case where only the license is sent to the user terminal via the insurance service server has been described, but the content is transferred via the insurance service server. It can also be sent to user terminals.
- the insurance service server performs conversion (packaging) for adding security condition information to the license, but a similar conversion may be performed for the content. In this case, when the content is played back on the user terminal, the guarantee condition information is displayed. Also, this conversion for licenses and contents need not be performed.
- the function of the insurance service server may be modularized and incorporated in the distribution server.
- the insurance service server is operated independently of the distribution server.
- the same service provider may operate the insurance service server and the distribution server.
- a configuration may be adopted in which an insurance service server that guarantees a license and an insurance service server that guarantees content are combined.
- the insurance service server of this system it is possible to distribute the upgraded content license to user terminals. If the content is upgraded, the distribution service provider (or the insurance service provider notified by the distribution service provider) notifies the user to that effect and responds to the user's request. Based on this, the insurance service server redistributes the license for the upgraded content. At this time, the insurance service server 50 redistributes the version-updated license of the content by the same procedure as the license redistribution in FIG. 12 and responds to the user's request. The insurance service server 50 manages the license corresponding to each version of the content in the redistribution history DB 53 and the license list 56, and distributes the upgraded licenses in duplicate and the old version after the version upgrade. Content reproduction or the like. Therefore, the distribution service provider can entrust the user response to the purge up to the insurance service server. Further, the user can surely acquire the license of the upgraded content through the insurance service server 50.
- the specifications of the user terminal can be used for distribution services.
- the service does not support the content delivery and storage format standards (for example, one is CD (Compact Disc) audio, the other is DVD (Digital Video Disc) audio, one is MP3 and the other is AA C), and insurance services can mediate to ensure that content is stored on user terminals.
- CD Compact Disc
- DVD Digital Video Disc
- MP3 Digital Video Disc
- this system for the interchange of heterogeneous media content (for example, the exchange of mobile downloaded content with broadcast content).
- an insurance server that manages multiple insurance service servers for each media is prepared, and the servers are connected hierarchically.
- the insurance server that guarantees the redistribution of the electronically distributed permission data guarantees the redistribution of the license that permits the reproduction of the content as the permission data, and enrolls in the insurance.
- the license issued by the distribution service provider is redistributed to the user terminal of the user in response to the request of the user, and the redistribution of the permission data for electronic distribution Insurance system
- storage means for storing the insurance policy issued by the insurance server and the encrypted content, and the license acquired through the insurance server are stored, and when the content is reproduced, the validity of the license for the content is checked.
- Determining license use determining means when the license is valid, reproducing means for decrypting the content by using a decryption key included in the license, and when the license or the content is lost, the license
- reproducing means for decrypting the content by using a decryption key included in the license
