    Abstract: A verification terminal includes a storage unit that stores partial block data. The partial block data is the latest data that a part of block data for update and addition in chronological order. The verification terminal selects a plurality of approval terminals to approve the partial block data stored in the storage unit. When a transaction included in the partial block data stored in the storage unit is updated by the verification terminal, the verification terminal transmits an approval request that requests the selected approval terminals to approve the updated partial block data to which the updated transaction and a hash value of the partial block data before updating are added. The verification terminal executes an update process of the partial block data based on approval results returned from the approval terminals in response to the approval request transmitted by the approval requesting unit.

    Abstract: A wakefulness maintenance apparatus includes a presentation recording unit and a presentation execution unit. The presentation recording unit records in-vehicle presentation contents each including a corresponding one of scenes, an auditory stimulus action associated with the scene, and at least one stimulus action selected from a group of a visual stimulus action, a tactile stimulus action, and an olfactory stimulus action which are associated with the scene. The presentation execution unit executes, based on the in-vehicle presentation contents recorded in the presentation recording unit, an in-vehicle presentation including provision of: the auditory stimulus action associated with the scene, and the at least one stimulus action selected from the group of the visual stimulus action, tactile stimulus action, and olfactory stimulus action which are associated with the scene.

    Abstract: In a verification terminal for verifying properness of an information item composed of a data string, a storage unit stores an own-terminal information item comprised of a data string, and a verification value generation unit generates a hash value of the own-terminal information item stored in the storage unit as an own-terminal hash value. A verification value acquisition unit communicates with at least one other verification terminal that should store an other-terminal information item t to thereby acquire a hash value of the other-terminal information item from the at least one other verification terminal as an other-terminal hash value. The other-terminal information item is conditioned to be identical to the own-terminal information item. A verification execution unit verifies properness of the own-terminal information item in accordance with whether the own-terminal hash value is consistent with the other-terminal hash value.
