Navigation apparatus and processing method of the same

A navigation apparatus comprising:

• a receiving section of an electronic processor of the navigation apparatus for receiving program via a communication unit;
• a monitoring section of the electronic processor for monitoring whether or not there is any predetermined unauthorized device access during executing the program received by the receiving section;
• and
• an execution control section of the electronic processor for canceling executing the program if it is determined that there is any predetermined unauthorized device access by the monitoring section.

A navigation apparatus comprising:

• a receiving section of an electronic processor of the navigation apparatus for receiving program via a communication unit;
• a monitoring section of the electronic processor for monitoring whether or not there is any predetermined unauthorized device access during executing the program received by the receiving section;
• and
• an authorizing section of the electronic processor for authorizing the program if it is determined that there has been no predetermined unauthorized device access in a predetermined time period by the monitoring section.

A navigation apparatus comprising:

• a downloading section of an electronic processor of the navigation apparatus for downloading program via a communication unit;
• a driving determining section of the electronic processor for determining whether or not a vehicle equipped with the navigation apparatus is running if an execution request for the program is received;
• an electronic signature determining section of the electronic processor for determining whether or not the program is attached with an electronic signature if it is determined that the vehicle is running by the driving determining section;
• a program activating section of the electronic processor for activating the program if it is determined that the program is attached with the electronic signature by the electronic signature determining section;
• a device access determining section of the electronic processor for activating the program and determining whether or not there is any predetermined unauthorized device access during executing the program if it is determined that the program is attached with no electronic signature;
• a selection receiving section of the electronic processor for outputting warning and receiving a selection of whether execution of the program should be canceled or not if there is any predetermined unauthorized device access;
• and
• an execution selecting section of the electronic processor for canceling the execution of the program if it is selected that the execution of the program should be canceled and if it is determined that there is any predetermined unauthorized device access during execution of the program, or maintaining the execution of the program if it is selected that the execution of the program should not be canceled.

A processing method carried out in an electronic processor of a navigation apparatus comprising:

• a receiving step of receiving program via a communication unit of the electronic processor;
• a driving determining step of determining whether or not a vehicle equipped with the navigation apparatus is running if a start request for the program is received in the communication unit;
• an execution control step of activating the program if it is determined that the vehicle is running at the driving determining step and also if the program received at the receiving step is authorized in the electronic processor;
• and
• a monitoring step for monitoring whether or not there is any unauthorized device access during the executing of the program received at the receiving step,
• wherein the execution control step further cancels executing the program if it is determined that the vehicle is running at the driving determining step and also if the program received at the receiving step is not authorized in the electronic processor, and if it is determined that there is any unauthorized device access during execution of the program at the monitoring step.
