(Step S302) For each user general information (user general information ID) provided to a business partner, the privilege determination unit 13 specifies users (privilege grantees) whose user information is used in the user general information. The user general information (user general information ID) provided to the business partner is the user general information (user general information ID) in which the history data of the user general information is stored in the user general information management information 202 . The privilege-granting target user is a user having a user ID associated with the user general information ID of the user general information in the user management information 201 (see FIG. 3), and a user ID list (user specific information) related to the user general information. is a user identified by

(Step S303) Based on the history data of the user general information stored in the user general information management information 202, the privilege determination unit 13 determines the user whose user information is used in the user general information (privilege grant target user) Determine the benefits granted.

The privilege determining unit 13 grants a privilege to each user general information (user general information ID) based on the number of times the user general information is provided, the consideration for the provision, the number of times of use at the business partner, etc. included in the history data of the user general information. Determining the benefits to be granted to the target user. For example, the privilege determining unit 13 may determine the privilege to be granted to the privilege-granting target user based on at least one of the number of times the user general information is provided, the consideration for the provision, and the number of times of use at the business partner. For example, when the number of times the user general information is provided is equal to or greater than a predetermined number of times, a predetermined privilege may be given to the privilege-granting target user. For example, a predetermined privilege may be given to the privilege-granting target user when the consideration for providing the user general information is equal to or greater than a predetermined amount. For example, when the number of times of use at a business partner is equal to or greater than a predetermined number of times, a predetermined privilege may be given to the privilege-granting target user. Further, a plurality of conditions among the number of times of provision of the user general information, the consideration for provision, and the number of times of use by business partners may be combined. A benefit may be, for example, a distribution of the consideration provided.

The privilege determination unit 13 stores privilege grant information indicating the determined privilege for each privilege grant target user in the user management information 201 (see FIG. 3) in association with the user ID and the corresponding user general information ID.

(Step S304) Based on the privilege granting information stored in the user management information 201, the privilege determining unit 13 transmits a privilege granting notification that notifies a privilege granted to the privilege granting user to the user terminal 2 of the privilege granting user. Send to

Note that the user general information may be composed of a plurality of pieces of partial information. For example, the user general information may be composed of a plurality of pieces of statistical information (partial information) such as information obtained by averaging movement histories of a plurality of users and a frequency distribution. Further, the information providing unit 12 may provide information to business partners in units of partial information.

In addition, the information provision management server 1 sends a partial user ID list (partial user identification information) that identifies users corresponding to user information used in each of a plurality of pieces of partial information included in the user general information to the user information management server 7. may be received from One partial user ID list is a list of user IDs of all users whose user information is used for one partial information.

Further, the privilege determining unit 13 may determine a privilege to be given to the user specified in the partial user ID list related to the partial information in response to the provision of the partial information to the trading partner. . The privilege determination unit 13 may record the history of the partial information provided to the business partner and determine the privilege based on the history. The privilege determining unit 13 may determine the privilege based on at least one of the number of times the partial information is provided, the consideration for the provision, and the number of times the partial information is used by the business partner.

According to the above-described embodiment, in response to the provision of the user general information recorded using the blockchain 5 or the user general information associated with related information related to the user general information to the business partner, the user general information A privilege granted to a user identified in a user ID list (user identification information) on information can be determined. As a result, it is possible to obtain the effect of increasing the user's motivation to provide information by giving the privilege.

In addition, the user can recognize that his/her own information has been used for general user information whose uniqueness and owner can be verified by the block chain by granting the privilege. This allows the user to understand how his or her information is being used, thereby reducing the user's anxiety about information provision and improving the user's motivation to provide information. can contribute.

Note that location information of each user (for example, mobile terminal movement history) may also be recorded using the blockchain 5 . Thereby, each user's location information can be managed on the blockchain 5 . Further, when the user's location information managed on the blockchain 5 matches a predetermined privilege granting condition, the user may be granted a predetermined privilege. For example, one or a plurality of stamp granting bases are determined in advance as privilege granting conditions, and when the user's location information managed on the blockchain 5 matches the stamp granting base, the user is given a predetermined privilege. Give. As a result, for example, in a stamp rally involving a plurality of stamp granting bases, location information of participating users can be managed using the blockchain 5 .

As a result, it is possible to improve the overall service quality in systems that provide information services, for example. It will be possible to contribute to the promotion of sustainable industrialization and the expansion of innovation.
