Abstract

Wrongful authentication process is prevented. A passive entry authenticating section compares an identification signal sent from a portable unit with an identification signal previously stored in a storage section. A biometrics authenticating section compares the biometrics information of a user inputted through a sensor section with the biometrics information registered in a biometrics database. A control section authenticates an authorized user when there is agreement in both the identification-signal comparison result and the biometrics-information comparison result, and controls a lock system to unlock the door lock of the automobile.

Claims

1. An authenticating apparatus comprising:

a receiving section for receiving an identification signal of a portable unit transmitted from the portable unit through radio communication;

an identification signal storing section for storing one or more of previously registered identification signals of portable units;

a sensor section for requesting biometrics information or a identification signal, wherein the sensor section requests biometric information if a person has registered biometrics information and requests an identification signal if a person has not registered biometrics information;

portable-unit authenticating section for comparing a received identification signal with a stored identification signal to confirm whether the both identification signals are in agreement or not;

an information input section for inputting biometrics information;

an information storing section for storing biometrics information on one or more of previously registered persons;

a person authenticating section for comparing input biometrics information with stored biometrics information to confirm whether the both pieces of biometrics information are in agreement or not;

a determining section for determining whether authentication results of the portable-unit authenticating section and the person authenticating section are respectively authentication results in agreement or not;

wherein the information storing section stores the biometrics information of the previously registered person and a unique person identification number corresponding to the biometrics information, the portable unit storing the unique person identification number together with the identification signal, the receiving section receiving the unique person identification number together with the identification signal through radio communication from the portable unit, the person authenticating section invoking, from the information storing section, biometrics information corresponding to the unique person identification number received by the receiving section to compare invoked biometrics information with the inputted biometrics information thereby carrying out personal authentication; and

wherein the personal identification number is classified with a first-kind personal identification number representing an owner of the authenticating apparatus or an appliance incorporating the authenticating apparatus and a second personal identification number representing a user other than the owner, further comprising a registration control section for controlling the information input section and the information storing section in order to register the biometrics information and the personal identification number, the registration control section confirming a previous registration of the first-kind personal identification number and the biometrics information with correspondence and a previous input of the biometrics information corresponding to the first-kind personal identification number from the information input section, to thereafter carry out control for registering the second-kind personal identification number and the biometrics information with correspondence.

2. An authenticating apparatus according to claim 1, wherein the registration control section, when the first-kind personal identification number and the biometrics information have been registered with correspondence, carries out control to delete all of the already stored second-kind personal identification numbers and the biometrics information corresponding thereto from the information storing section.

3. A method of registering a person to an authenticating apparatus or an appliance using an authenticating method comprising the steps of:

receiving an identification signal of a portable unit transmitted from the portable unit through radio communication;

comparing a received identification signal with a previously registered identification signal to confirm whether both identification signals are in agreement or not thereby carrying out authentication of the portable unit;

accepting an input of biometrics information if a person has registered biometrics information or accepting an input of a portable unit ID if a person has not registered biometrics information;

if a portable unit ID is accepted, comparing the inputted portable unit ID with a previously registered portable unit ID and determining whether the inputted portable unit ID is the previously registered ID;

if biometrics information is accepted, comparing inputted biometrics information with previously registered biometrics information to confirm whether the both pieces of biometrics information are in agreement or not thereby carrying out authentication of a person; and

determining whether an authentication result of the portable unit and an authentication result of the person are, both, in agreement or not;

wherein the previously registered biometrics information is stored together with a unique personal identification number corresponding to the biometrics information, the identification signal and unique personal identification number stored within the portable unit being received through radio communication from the portable unit on the other hand, biometric information corresponding to the unique personal identification number obtained by the reception being invoked in the personal authentication and compared with the inputted biometrics information thereby carrying out personal authentication; and

wherein the personal identification number is classified with a first-kind personal identification number representing an owner of the authenticating apparatus or appliance and a second-kind personal identification number representing a user other than the owner, a previous registration of the first-kind personal identification number and the biometrics information with correspondence and a previous input of the biometrics information corresponding to the first-kind personal identification number being confirmed to thereafter register the second-kind personal identification number and the biometrics information with correspondence.

4. A method of registering a person according to claim 3, wherein, when the first-kind personal identification number and the biometrics information are registered with correspondence, the already stored second-kind personal identification numbers and the biometrics information corresponding thereto are all deleted.

5. An authenticating apparatus comprising:

a receiving section for receiving an identification signal of a portable unit transmitted from the portable unit through radio communication;

an identification signal storing section for storing one or more of previously registered identification signals of portable units;

portable-unit authenticating section for comparing a received identification signal with a stored identification signal to confirm whether the both identification signals are in agreement or not;

an information input section for inputting biometrics information;

an information storing section for storing biometrics information on one or more of previously registered persons and a unique person identification number corresponding to the biometrics information;

a communicating section for transmitting the unique person identification number from the information storing section;

a person authenticating section for comparing input biometrics information with stored biometrics information to confirm whether the both pieces of biometrics information are in agreement or not; and

a determining section for determining whether authentication results of the portable-unit authenticating section and the person authenticating section are respectively authentication results in agreement or not;

wherein the information storing section stores the biometrics information of the previously registered person and the unique person identification number corresponding to the biometrics information, the portable unit storing the unique person identification number which is transmitted by the communicating section together with the identification signal, the receiving section receiving the unique person identification number together with the identification signal through radio communication from the portable unit, the person authenticating section invoking, from the information storing section, biometrics information corresponding to the unique person identification number received by the receiving section to compare invoked biometrics information with the inputted biometrics information thereby carrying out personal authentication.
