Fingerprint data reset system and fingerprint data reset method

A fingerprint data reset system, comprising:

• a vehicle comprising a first controller configured to authenticate input fingerprint data based on comparison between the input fingerprint data and registered fingerprint data;
• and
• an on-board diagnostics configured to communicate with a plurality of controllers of the vehicle through an in-vehicle communication network of the vehicle,
• wherein the on-board diagnostics is configured to display a first element for inputting a personal identification number (PIN) and a vehicle identification number (VIN), a second element for determining a location of a digital key, and a third element for a biometric authentication, and transmit a fingerprint reset request signal to the first controller among the plurality of controllers based on receiving a user input for resetting the registered fingerprint data, and
• the first controller is configured to determine whether the user input is received from a user of the vehicle based on the fingerprint reset request signal, and reset the registered fingerprint data based on a determination that the user input is received from the user of the vehicle,
• wherein the fingerprint reset request signal includes a command to request authentication of the PIN and the VIN input by the user, a command to request authentication of a digital key, or a command to request a biometric authentication other than fingerprint authentication,
• wherein the first controller is configured to:
• (i) generate an encryption value corresponding to the PIN and the VIN input by the user, and determine a first positive signal based on the generated encryption value matching a pre-stored encryption value which is set by encrypting a unique PIN and a unique VIN of the vehicle, and wherein the unique PIN and the unique VIN of the vehicle are invariable according to a setting of the user, or
• (ii) transmit a search request signal for requesting identification of the location of the digital key, to a second controller among the plurality of controllers, based on receiving the command to request authentication of the digital key,
• the second controller is configured to identify the location of the digital key, based on the search request signal received from the first controller, and transmit a second positive signal to the first controller based on the location of the digital key being identified to be located in the vehicle, or
• (iii) transmit a result request signal for requesting a result of the biometric authentication, to a third controller among the plurality of controllers, based on receiving the command to request the biometric authentication, the third controller is configured to perform the biometric authentication, based on the result request signal received from the first controller, and transmit a third positive signal to the first controller based on the biometric authentication being successful, and
• based on whether the first positive signal, the second positive signal, or the third positive signal is received, the first controller is configured to reset the registered fingerprint data based on at least one of the first positive signal, the second positive signal, or the third positive signal was received.
