In-vehicle device, information processing method and computer-readable medium

An information processing method comprising causing an in-vehicle device configured to perform transmission processing for transmitting at least a part of a plurality of information pieces stored in a storage to a predetermined transmission destination to:

• transmit a list including information that identifies the plurality of information pieces, respectively, to a first in-vehicle device of other in-vehicle devices;
• receive a first list including information that identifies information pieces each held by any of the other in-vehicle devices including the first in-vehicle device from the first in-vehicle device, through a first communicator used for transmission with the other in-vehicle devices;
• and
• when a first information piece is present in the storage, determine whether or not to transmit the first information piece in the transmission processing depending on whether or not a predetermined condition is met, wherein information that identifies the first information piece is included in both the first list and the list.

A non-transitory computer-readable medium recorded with an information processing program for causing a computer to:

• perform transmission processing for transmitting at least a part of a plurality of information pieces stored in a storage to a predetermined transmission destination;
• transmit a list including information that identifies the plurality of information pieces, respectively, to a first in-vehicle device of other in-vehicle devices;
• receive a first list including information that identifies information pieces each held by any of the other in-vehicle devices including the first in-vehicle device from the first in-vehicle device, through a first communicator used for transmission with the other in-vehicle devices;
• and
• when a first information piece is present in the storage, determine whether or not to transmit the first information piece in the transmission processing depending on whether or not a predetermined condition is met, wherein information that identifies the first information piece is included in both the first list and the list.
