Abstract: Provided is a technology that allows use of a trend rating acquired more objectively. A POI information providing device includes: a storage unit which stores POI data including a POI name; a posted data acquisition unit which acquires posted data through a network; a trend rating acquisition unit which obtains a matching degree between a word included in the posted data and the POI name for each piece of the posted data, and uses a predetermined calculation expression for the matching degree to calculate and acquire a trend rating indicating an attention degree of a POI; a trend rating identification unit which identifies, when a request for the trend rating is received from another device connected through the network, the trend rating corresponding to the request; and a transmission unit which transmits the trend rating identified by the trend rating identification unit to the another device.

Abstract: Inherent terminal identification information and a terminal unique key are stored in an on-board terminal, and server-side terminal identification information and a server-side terminal unique key, which are same information as the above terminal identification information and terminal unique key are stored in a server. And, the on-board terminal transmits the terminal identification information to the server via a communication terminal, and the server performs terminal authentication according to the server-side terminal identification information, and if the authentication is success, transmits encrypted software for the on-board terminal of which authentication was success to the communication terminal.

Abstract: A vehicle-onboard apparatus system, comprises a portable terminal and a vehicle-onboard machine that are configured to be coupled to each other for communication. The portable terminal and the vehicle-onboard machine each store operation logs including operation contents thereof. When an operation of the vehicle-onboard machine and an operation of the portable terminal relate to each other, an operation log resulting from the operation of the vehicle-onboard machine and an operation log resulting from the operation of the portable terminal are associated with each other by first identification information. The vehicle-onboard machine makes a user to recognize the first identification information corresponding to an operation causing detected predetermined state. When the portable terminal receives an input of the first identification information presented by the vehicle-onboard machine, the portable terminal acquires the operation log associated with the input first identification information.

Abstract: A program manager operating on a smartphone transmits information of an onboard apparatus and a program ID list of the smartphone to the server. The server determines the possibility of an expansion of one or more programs, and the difference between charge/free provisioning of the program. If a function expansion condition of the program is met, the server transmits it to the smartphone. The program manager of the smartphone inquires as to possibility/impossibility of expansion, and a password (when there is a charge), and transmits the authentication information and the password (if there is a charge), which are produced from an onboard apparatus ID, a random number, secret data unique to the onboard apparatus, etc., to the server. The server transmits function expansion data to the smartphone, when succeeding the authentication, and the program management portion executes the function expansion of the program.
