In-vehicle apparatus, authentication method, and computer readable medium
An authentication pattern generation unit, if a signal from a portable device is received, prompts a user who uses the portable device to perform a specific action. A checking unit determines whether or not the user has performed the specific action. If the checking unit determines that the user has performed the specific action, the checking unit authenticates that the portable device is an authorized device.
1. An in-vehicle apparatus mounted on a vehicle, the in-vehicle apparatus comprising:
processing circuitry to:
if a signal from a radio communication device is received, cause a lighting device to light up an area around feet of a person who is close to the vehicle, the lighting device being installed in the vehicle so as to light up the area, and prompt a user who uses the radio communication device to perform a specific action;
determine whether or not the user has performed the specific action; and
if it is determined that the user has performed the specific action, authenticate that the radio communication device is an authorized device,
wherein the processing circuitry selects as the specific action, an action associated with an identifier (ID) of the user from among a plurality of actions associated with IDs of a plurality of users, and prompts the user to perform the selected action as the specific action.
2. The in-vehicle apparatus according to claim 1 , wherein the processing circuitry causes the lighting device installed on a side of the vehicle to light up the area, and prompts the user to perform an action of stepping along the side of vehicle, as the specific action.
3. The in-vehicle apparatus according to claim 1 , wherein the processing circuitry prompts the user to perform the specific action via an alarming device installed in the vehicle on which the in-vehicle apparatus is mounted.
4. The in-vehicle apparatus according to claim 1 , wherein the processing circuitry prompts the user to perform the specific action by communicating with the radio communication device.
5. The in-vehicle apparatus according to claim 1 , wherein the processing circuitry senses movement of the user, and determines whether or not the user has performed the specific action.
6. The in-vehicle apparatus according to claim 1 , wherein the processing circuitry receives from the radio communication device, a result of measurement of a motion sensor installed in the radio communication device, and determines whether or not the user has performed the specific action using the received result of measurement.
7. The in-vehicle apparatus according to claim 1 , wherein the processing circuitry changes at least one action of the plurality of actions based on an instruction from the outside.
8. An authentication method comprising:
if a signal from a radio communication device is received, causing a lighting device to light up an area around feet of a person who is close to a vehicle, the lighting device being installed in the vehicle so as to light up the area, and prompting a user who uses the radio communication device to perform a specific action;
determining whether or not the user has performed the specific action; and
if it is determined that the user has performed the specific action, authenticating that the radio communication device is an authorized device,
wherein the processing circuitry selects as the specific action, an action associated with an identifier (ID) of the user from among a plurality of actions associated with IDs of a plurality of users, and prompts the user to perform the selected action as the specific action.
9. A non-transitory computer readable medium storing an authentication program that causes a computer to execute:
an action prompting process of causing a lighting device to light up an area around feet of a person who is close to a vehicle, the lighting device being installed in the vehicle so as to light up the area, and prompting a user who uses a radio communication device to perform a specific action if a signal from the radio communication device is received;
a determination process of determining whether or not the user has performed the specific action; and
an authentication process of authenticating that the radio communication device is an authorized device if it is determined by the determination process that the user has performed the specific action,
wherein the processing circuitry selects as the specific action, an action associated with an identifier (ID) of the user from among a plurality of actions associated with IDs of a plurality of users, and prompts the user to perform the selected action as the specific action.
