Abstract: Provided is a control method of controlling locking or unlocking of storage using a blockchain. The control method includes: determining, when first request information indicating a lock/unlock request, that is a lock request or an unlock request, is received from a terminal, whether a keyholder identified by reading keyholder information stored in the blockchain matches an owner of the terminal that has transmitted the first request information, the keyholder information indicating a person having the authority to lock or unlock the storage; performing lock/unlock processing when the keyholder is determined to match the owner, the lock/unlock processing being processing for causing the storage to lock or unlock in accordance with the first request information; and performing first storage processing after the lock/unlock processing is performed, the first storage processing being processing of storing, in the blockchain, transaction data indicating that the lock/unlock processing has been performed.

Abstract: A control method of controlling, using a distributed ledger, locking or unlocking of one or more storage units, in each of which an item is storable, includes: operating a first smart contract and one or more second smart contracts by a code, stored in the distributed ledger, being executed by a computer, the first smart contract managing the one or more second smart contracts that are in one-to-one correspondence with the one or more storage units; controlling, by each of the one or more second smart contracts, locking or unlocking of a corresponding one of the one or more storage units, the controlling being performed under the management by the first smart contract; and controlling, by the first smart contract, whether to place each of the one or more second smart contracts under the management.

Abstract: A management system includes: a right holder information storage unit which stores right holder information about a right holder entitled to use a delivery locker device; an agreement formation unit which creates a block of a blockchain that includes a processing instruction, and stores the block into a block storage unit; a terminal device which transmits an assignment processing instruction; a process execution unit which, when obtaining the assignment processing instruction included in the block, updates the current right holder included in the right holder information; and a condition checking unit which, when determining that the condition for assignment fails to be met, creates a return processing instruction and transmits the return processing instruction to the agreement formation unit. When obtaining the return processing instruction included in the block, the process execution unit updates the right holder information.

Abstract: In information display apparatus 100 having voice call means 101, data on a sender database 104 is retrieved by data retrieval means 103 based on the sender number acquired via calling number acquisition means 102. Application selection means 109 uses terminal resource acquisition means 108 or network resource acquisition means 106 to acquired the resource described in the sender data based on the retrieved sender data and selects the application corresponding to the resource. Display means 111 displays the acquired resource via the application. This displays data related to the sender at call incoming, thus allowing the user to quickly recognize the information on the sender thus enhancing the convenience related to a call.
