Abstract
The present disclosure relates to an electronic device that is capable of multimodal biometric authentication and a method of controlling the electronic device.
Claims11
An electronic device that performs multimodal biometric authentication, the device comprising:
- a terminal unit that includes
- multiple sensors which are formed to detect biometric information, and
- at least one terminal which includes an input unit formed to receive a personal identification number as an input;
- a controller that receives the personal identification number and the biometric information sensed from a user, from the terminal unit, and registers the received biometric information, as biometric authentication information corresponding to the personal identification number received together, in an authentication information database, when performing new user registration, and that selects only pieces of biometric authentication information corresponding to the personal identification number that is input, from among pieces of biometric authentication information stored in the authentication information database, and forms a comparison group for the user authentication, if the user's personal identification number and biometric information are input from the terminal unit, when performing user authentication;
- and
- a security module that compares the comparison group and the biometric information that is input from the terminal unit and thus performs the user authentication.
3 more elements
A method of controlling an electronic device that performs multimodal biometric authentication, the method comprising:
- a first step of receiving personal identification information and biometric information through a first terminal included in the electronic device, when performing new user registration;
- a second step of storing the received biometric information, as biometric authentication information corresponding to the personal identification information received together, in an authentication information database;
- a third step of acquiring user's personal identification information and user's biometric information through a second terminal included in the electronic device, when performing user authentication;
- a fourth step of selecting pieces of biometric authentication information that correspond to the personal identification information which is input through the second terminal, from among pieces of biometric authentication information stored in the authentication information database;
- a fifth step of setting the pieces of biometric authentication information selected in the fourth step, as a comparison group for the user authentication;
- and
- a sixth step of comparing each of the pieces of biometric authentication information included in the comparison group and the biometric information acquired through the second terminal and thus performing the user authentication.
