The regional information is distributed to the terminal device 20. At this time, the information distribution unit 76 controls the distribution of the area information based on the determination result of the area information by the reliability determination unit 72.

  For example, the information distribution unit 76 distributes the area information whose reliability is determined to be 50% or more by the reliability determination unit 72, and the area information whose reliability is determined to be less than 50%. Restrict delivery. In this way, it is possible to restrict distribution of information with low reliability (incorrect information or fake information) among regional information uploaded by the user, and to distribute only reliable regional information.

  In addition, the information distribution unit 76 distributes the reliability information (for example, reliability: 100%) indicating the reliability determined by the reliability determination unit 72 together with the area information received by the information reception unit 70. It may be. In this way, since the user who received the distribution of the regional information can grasp the reliability of the regional information, the possibility of erroneously recognizing incorrect information or false information as correct information is reduced. In addition, for delivery of regional information, for example, other delivery methods using a communication protocol such as mail transmission or HTTP (Hyper Text Transfer Protocol) can be used.
