Personal information protection device for vehicle and personal information protection mehtod thereof and vehicle including the same

A personal information protection method of a personal information protection device for vehicles including a communication unit connected to control devices of a vehicle for communication, and a controller configured to determine whether to approve data communication of a control device which intends to perform data communication with an outside device, the personal information protection method comprising:

• the controller checking whether a first control device which intends to perform data communication with the outside device is present among the control devices of the vehicle through the communication unit;
• the controller extracting first unique data stored when previous last data communication is performed from the first control device when the first control device which intends to perform data communication with the outside device is present;
• the controller extracting second unique data stored when previous last data communication is performed from a second control device other than the first control device;
• the controller checking whether the extracted first unique data is consistent with the extracted second unique data;
• the controller determining approval of data communication of the first control device if the extracted first unique data is consistent with the extracted second unique data;
• the controller acquiring second unique data corresponding to a data communication start time from the second control device upon determination of approval of data communication of the first control device;
• and
• the controller updating the first unique data of the first control device on the basis of the acquired second unique data.

A personal information protection method of a personal information protection device for vehicles including a controller configured to determine whether to approve data communication of a charging control device which intends to perform data communication with an external charger, the personal information protection method comprising:

• the controller checking whether the charging control device of a vehicle is connected to an external charger for data communication;
• the controller checking whether there is an authentication certificate related to a vehicle charging service when the charging control device of the vehicle is connected to an external charger for data communication;
• the controller extracting first unique data stored when previous last data communication is performed from the charging control device when the authentication certificate is present;
• the controller extracting second unique data stored when previous last data communication is performed from a control device other than the charging control device;
• the controller checking whether the extracted first unique data is consistent with the extracted second unique data;
• the controller determining that the current state is a normal condition and determining approval of data communication of the charging control device if the extracted first unique data is consistent with the extracted second unique data;
• the controller acquiring second unique data from the control device other than the charging control device upon determination of approval of data communication of the charging control device;
• the controller updating the first unique data of the charging control device on the basis of the acquired second unique data;
• and
• the controller controlling the charging control device to perform data communication with the external charger to start charging when the first unique data has been updated.
