1. An information distribution system including a communication terminal, an on-board terminal configured to connect to the communication terminal by wire or wireless, and a server, wherein:

  • the on-board terminal is provided with;

    an on-board terminal identification information datastore configured to store terminal identification information inherent to the on-board terminal,an authentication information generator configured to generate the on-board terminal authentication information including the terminal identification information stored in the on-board terminal identification datastore, andan inter-terminal equipment communicator configured to transmit the authentication information generated by the authentication information generator to the communication terminal,the communication terminal is provided with;

    an inter-equipment communicator configured to connect to the on-board terminal by wire or wireless,a communication terminal datastore configured to store the on-board terminal authentication information received by the inter-equipment communication section, anda server communicator configured to transmit the on-board terminal authentication information stored in the communication terminal datastore to the server,the server is provided with;

    a terminal communicator configured to receive the on-board terminal authentication information from the communication terminal,an authentication information verifier configured to authenticate the on-board terminal authentication information received by the terminal communication section,a last authentication timestamp datastore configured to store a timestamp when authentication is successfully verified by the authentication information verifier, andan authentication information manager configured to store the timestamp, when the authentication is successfully verified by the authentication information verifier, into the last authentication timestamp datastore, andwherein the server, when it receives the on-board terminal authentication information from the communication terminal, is configured to authenticate the on-board terminal authentication information using a timestamp when the on-board terminal authentication information is authenticated by the authentication information verifier, and a timestamp stored in the last authentication timestamp datastore, andwherein the authentication information verifier is further configured to manage an expiration date of the on-board terminal software using a last authentication timestamp inherent to the on-board terminal software stored in the software management database.
