Abstract
A data management method performed by a first authentication server included in a plurality of authentication servers each having a distributed ledger in a data management system including a device and the plurality of authentication servers includes: obtaining first transaction data generated by the device and including device data obtained or generated by the device; and generating a block including the first transaction data and recording the generated block in the distributed ledger, when the device data included in the first transaction data is first data indicated in an information type list which is a data list indicating data that is subject to recording in the distributed ledger and related to a predetermined contract.
Claims13
A data management method performed by a first authentication server included in a plurality of authentication servers in a data management system including the plurality of authentication servers and a device, each of the plurality of authentication servers having a distributed ledger, the data management method comprising:
- obtaining first transaction data generated by the device, the first transaction data including device data obtained or generated by the device;
- and
- generating a block including the first transaction data and recording, in the distributed ledger, the block generated, when the device data included in the first transaction data is first data indicated in an information type list which is a data list indicating data that is subject to recording in the distributed ledger and related to a predetermined contract, wherein
- the predetermined contract is a contract related to electric power or a contract related to linkage between IoT devices, and
- the device data is data related to electric power or data related to linkage between IoT devices.
A data management system, comprising:
- a plurality of authentication servers each having a distributed ledger;
- and
- a device, wherein
- a first authentication server included in the plurality of authentication servers includes:
- an obtainer that obtains first transaction data generated by the device, the first transaction data including device data obtained or generated by the device;
- a transaction data verifier that verifies the first transaction data when the device data included in the first transaction data is first data indicated in an information type list which is a data list indicating data that is subject to recording in the distributed ledger and related to a predetermined contract;
- and
- a synchronizer that generates a block including the first transaction data and records, in the distributed ledger, the block generated;
- the predetermined contract is a contract related to electric power or a contract related to linkage between IoT devices;
- and
- the device data is data related to electric power or data related to linkage between IoT devices.
A non-transitory computer-readable recording medium having a program causing a computer to execute a data management method that is performed by a first authentication server included in a plurality of authentication servers in a data management system including the plurality of authentication servers and a device, each of the plurality of authentication servers having a distributed ledger, the program causing the computer to execute:
- obtaining first transaction data generated by the device, the first transaction data including device data obtained or generated by the device;
- and
- generating a block including the first transaction data and recording, in the distributed ledger, the block generated, when the device data included in the first transaction data is first data indicated in an information type list which is a data list indicating data that is subject to recording in the distributed ledger and related to a predetermined contract, wherein
- the predetermined contract is a contract related to electric power or a contract related to linkage between IoT devices, and
- the device data is data related to electric power or data related to linkage between IoT devices.
