When notification information about a company code is received from a center device, a control unit of an in-vehicle device refers to uplink information which is generated for each qualified delivery company and stored in a storage unit and cross-checks the company code included in the uplink information with the received company code (step S8). Only when those are identical, the uplink information corresponding to the company code to which it is judged that those are identical is read out from the storage unit and written in an uplink information storage area of the storage unit of a DSRC unit (step S9). Security on content information delivery is improved. |
