## 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.

## Claims

### Claim 1

A control method of controlling locking or unlocking of storage using a blockchain, the control method comprising:
determining, when first request information indicating a lock/unlock request is received from a terminal, whether or not 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 lock/unlock request being a lock request or an unlock request, the keyholder information indicating a person having 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.

### Claim 2 (depends on 1)

The control method according to claim 1, further comprising:
performing second storage processing when second request information indicating a request to change the keyholder information is received from the terminal, the second storage processing being processing of storing the second request information in the blockchain;
determining, when the first request information is received, whether or not the second storage processing is currently being performed; and
controlling the lock/unlock processing in accordance with a result of the determining.

### Claim 3 (depends on 2)

The control method according to claim 2, wherein
the controlling of the lock/unlock processing includes
prohibiting the lock/unlock processing in accordance with the first request information.

### Claim 4 (depends on 2)

The control method according to claim 2, wherein
the controlling of the lock/unlock processing includes
standing by until the second storage processing finishes, and performing the lock/unlock processing after the second storage processing finishes.

### Claim 5 (depends on 4)

The control method according to claim 4, wherein
the controlling of the lock/unlock processing includes
displaying an image indicating standby until the second storage processing finishes.

### Claim 6 (depends on 1)

The control method according to claim 1, further comprising, when the storage has been caused to lock or unlock:
obtaining result information indicating whether or not the locking or unlocking has actually been performed; and
storing the transaction data in the blockchain only when the result information obtained indicates that the locking or unlocking has actually been performed.

### Claim 7 (depends on 1)

The control method according to claim 1, wherein
the storing of the transaction data in the blockchain includes
generating a block including the transaction data, and storing the transaction data in the blockchain when a consensus is reached on the block generated.

### Claim 8

An information processing device that is one of a plurality of information processing devices and controls locking or unlocking of storage using a blockchain, the information processing device comprising:
a processor;
memory; and
a storage device that stores a distributed ledger in a form of the blockchain, wherein
the blockchain stores keyholder information indicating a person having authority to lock or unlock the storage, and
the processor, using the memory:
determines, when first request information indicating a lock/unlock request is received from a terminal, whether or not a keyholder identified by reading the keyholder information stored in the blockchain matches an owner of the terminal that has transmitted the first request information, the lock/unlock request being a lock request or an unlock request;
performs 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
performs 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.

### Claim 9 (depends on 8)

A management system, comprising:
the plurality of information processing devices including the information processing device according to claim 8; and
the storage of which locking or unlocking is controlled by the plurality of information processing devices using the blockchain.

### Claim 10 (depends on 1)

A non-transitory computer-readable recording medium for use in a computer, the recording medium having a computer program recorded thereon for causing the computer to execute the control method according to claim 1.
