Abstract

Claims (61)

1 . An information processing device controlling a target vehicle, the information processing device comprising:

a memory; and

a processor coupled to the memory, the processor being configured to:

measure a distance between the information processing device and the vehicle;

compare the measured distance to a predetermined distance;

when the measured distance is greater than or equal to the predetermined distance, implement biometric authentication processing of a user of the vehicle with audible range sound, and execute event display processing and user operation guidance processing to display guidance on a display section of the vehicle;

when the measured distance is less than the predetermined distance, implement biometric authentication processing of the user of the vehicle with inaudible range sound; and

control the vehicle based on a result of the biometric authentication processing,

wherein when the biometric authentication processing with audible range sound is not successful, the processor is configured to execute reattachment display processing to display a reattachment notice on the display section of the vehicle.

2 . The information processing device according to claim 1 , wherein the processor is configured to perform control such that an authorizer that is a separate body from the information processing device selectively implements the biometric authentication processing of the user with the audible range sound or the biometric authentication processing of the user with the inaudible range sound, the authorizer being attachable to an ear of the user and including a speaker and a microphone.

3 . The information processing device according to claim 2 , wherein the authorizer is configured such that the biometric authentication processing of the user implemented by the authorizer includes:

selectively outputting sound in an audible range or an inaudible range;

acquiring echo sound of the outputted sound;

extracting a feature from the echo sound; and

comparing the feature with a pre-registered feature of a legitimate user of the vehicle.

4 . The information processing device according to claim 2 , wherein the processor is configured to control the authorizer via the speaker and microphone to selectively implement the biometric authentication processing of the user with the audible range sound or the biometric authentication processing of the user with the inaudible range sound.

5 . The information processing device according to claim 4 , wherein the information processing device is attachable to the ear of the user, and the biometric authentication processing of the user implemented by the processor includes:

the speaker, selectively outputting sound in an audible range or an inaudible range;

via the microphone, acquiring echo sound of the outputted sound;

extracting a feature from the echo sound; and

comparing the feature with a pre-registered feature of a legitimate user of the vehicle.

6 . The information processing device according to claim 1 , wherein the processor is configured to:

recognize an operation by the user in response to the biometric authentication processing of the user being implemented with the audible range sound; and

control the vehicle based on the result of the biometric authentication processing and the recognized operation by the user.

7 . An information processing device controlling a vehicle, the information processing device comprising:

a memory and

a processor coupled to the memory, the processor being configured to:

acquire substance of an operation relating to the vehicle;

when the operation substance is a security unlocking operation of the vehicle, implement biometric authentication processing of a user of the vehicle with audible range sound, and execute event display processing and user operation guidance processing to display guidance on a display section of the vehicle;

when the operation substance is not the security unlocking operation of the vehicle, implement biometric authentication processing of the user of the vehicle with inaudible range sound; and

control the vehicle based on a result of the biometric authentication processing,

wherein when the biometric authentication processing with audible range sound is not successful, the processor is configured to execute reattachment display processing to display a reattachment notice on the display section of the vehicle.

8 . The information processing device according to claim 7 , wherein the processor is configured to perform control such that an authorizer that is a separate body from the information processing device selectively implements the biometric authentication processing of the user with the audible range sound or the biometric authentication processing of the user with the inaudible range sound, the authorizer being attachable to an ear of the user and including a speaker and a microphone.

9 . The information processing device according to claim 8 ,

wherein the authorizer is configured such that the biometric authentication processing of the user implemented by the authorizer includes:

via the speaker, selectively outputting sound in an audible range or an inaudible range;

via the microphone, acquiring echo sound of the outputted sound;

extracting a feature from the echo sound; and

comparing the feature with a pre-registered feature of a legitimate user of the vehicle.

10 . The information processing device according to claim 8 , further wherein the processor is configured to, via the speaker and the microphone, selectively implement the biometric authentication processing of the user with the audible range sound or the biometric authentication processing of the user with the inaudible range sound.

11 . The information processing device according to claim 10 , wherein the information processing device is attachable to the ear of the user, and the biometric authentication processing of the user implemented by the processor includes:

via the speaker, selectively outputting sound in an audible range or an inaudible range;

via the microphone, acquiring echo sound of the outputted sound;

extracting a feature from the echo sound; and

comparing the feature with a pre-registered feature of a legitimate user of the vehicle.

12 . The information processing device according to claim 7 , wherein the processor is configured to:

recognize an operation by the user in response to the biometric authentication processing of the user being implemented with the audible range sound; and

control the vehicle based on the result of the biometric authentication processing and the recognized operation by the user.

13 . An information processing method, comprising, by a processor:

measuring a distance between an information processing device and a vehicle;

comparing the measured distance to a predetermined distance;

when the measured distance is greater than or equal to the predetermined distance, implementing biometric authentication processing of a user of the target with audible range sound, and executing event display processing and user operation guidance processing to display guidance on a display section of the vehicle;

when the measured distance is less than the predetermined distance, implementing biometric authentication processing of the user of the vehicle with inaudible range sound; and

controlling the vehicle based on a result of the biometric authentication processing,

wherein when the biometric authentication processing with audible range sound is not successful, the method further comprises executing reattachment display processing to display a reattachment notice on the display section of the vehicle.

14 . An information processing method comprising, by a processor:

acquiring substance of an operation relating to a vehicle;

when the operation substance is a security unlocking operation of the vehicle, implementing biometric authentication processing of a user of the target with audible range sound, and executing event display processing and user operation guidance processing to display guidance on a display section of the vehicle;

when the operation substance is not the security unlocking operation of the vehicle, implementing biometric authentication processing of the user of the vehicle with inaudible range sound; and

controlling the vehicle based on a result of the biometric authentication processing,

wherein when the biometric authentication processing with audible range sound is not successful, the method further comprises executing reattachment display processing to display a reattachment notice on the display section of the vehicle.
