DATA CIRCULATION SUPPORT APPARATUS, DATA CIRCULATION SUPPORT METHOD AND PROGRAM

1 . A data circulation support apparatus comprising:

a memory; and

a processor configured to execute

calculating a score indicating reliability of a contract condition related to circulation of data based on information indicating a sense of value related to contract compliance of each of a user of a circulation source of the data and a user of a circulation destination of the data, and identifying a contract condition whose score is greater than or equal to a threshold; and

recording the contract condition in a ledger upon receiving information indicating approval to the contract condition by the user of the circulation source or the circulation destination.

2 . The data circulation support apparatus according to claim 1 , wherein the contract condition includes a type of a ledger that is a recording destination of the contract condition, and

wherein the processor records the contract condition in a ledger related to the type included in the contract condition.

3 . The data circulation support apparatus according to claim 1 , wherein the threshold value varies depending on information related to the data.

4 . The data circulation support apparatus according to claim 1 , the processor is further configured to execute

calculating information indicating the sense of value of a user based on action characteristic data of the user,

wherein the processor identifies the contract condition based on the information indicating the sense of value calculated for each user of the circulation source or the circulation destination.

5 . A data circulation support method, executed by a computer including a memory and a processor, the method comprising:

calculating a score indicating reliability to a contract condition related to circulation of data based on information indicating a sense of value related to contract compliance of each of a user of a circulation source of the data and a user of a circulation destination of the data, and identifying a contract condition whose score is greater than or equal to a threshold; and

recording the contract condition in a ledger upon receiving information indicating approval to the contract condition by the user of the circulation source or the circulation destination.

6 . A non-transitory computer-readable recording medium having computer-readable instructions stored thereon, which, when executed, cause a computer to function as the data circulation support apparatus according to claim 1 .
