Abstract

Various devices, methods, and media are provided. According to one of the devices, an unlocking request for unlocking a lock is received. The lock is provided in a container and contains a physical object. Information of a first owner, that has a right of ownership of the physical object, is acquired from a first ledger when the unlocking request is received. The first ledger is one of a plurality of distributed ledgers which each have a same content. The device determines whether the first requester matches the first owner, and causes the lock to be unlocked when the first requester matches the first owner.
