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 for performing multimodal biometric authentication, the electronic device comprising:
- a controller configured to:
- when performing new user registration, receive, from a first terminal, a personal identification number and biometric information sensed from a user;
- register and store the received biometric information as biometric authentication information corresponding to the personal identification number received in an authentication information database, wherein the authentication information database is a database in which biometric information of different registered users are grouped according to a string of numbers constituting a personal identification number input from each user such that biometric information corresponding to a same or similar personal identification number is stored into one group;
- when performing user authentication, receive, from a second terminal a personal identification number and biometric information sensed from a user;
- when performing the user authentication, receive, select pieces of biometric authentication information corresponding to the personal identification number that is input through a second terminal from among pieces of biometric authentication information stored in the authentication information database;
- and
- when performing the user authentication, form a comparison group for the user authentication based on the selected pieces of biometric authentication information;
- and
- a security module configured to compare the comparison group and the biometric information of the user that is input from the second terminal and to perform the user authentication, and
- when the personal identification number for user authentication is input from the second terminal, the controller is further configured to detect at least one group corresponding to the same or similar string of numbers to the input personal identification number and to set the detected at least one group as the comparison group,
- wherein the electronic device is connected to at least one terminal including multiple sensors for sensing the biometric information of the user and to an input for receiving the personal identification number from the user.

A method of controlling an electronic device that performs multimodal biometric authentication, the method comprising:
- when performing new user registration, receiving, from a first terminal, personal identification information and biometric information of a user;
- registering and storing the received biometric information as biometric authentication information corresponding to the personal identification information received in an authentication information database, wherein the authentication information database is a database in which biometric information of different registered users are grouped according to a string of numbers constituting a personal identification number input from each user such that biometric information corresponding to a same or similar personal identification number is stored into one group;
- when performing user authentication, acquiring, from a second terminal, personal identification information of the user and biometric information of the user;
- when performing user authentication, selecting pieces of biometric authentication information that correspond to the personal identification information input through the second terminal from among pieces of biometric authentication information stored in the authentication information database;
- setting the selected pieces of biometric authentication information as a comparison group for the user authentication by detecting at least one group corresponding to a same or similar number sequence to a personal identification number when the personal identification number for user authentication is input and setting the detected biometric information of at least one group as the comparison group;
- and
- comparing each of the pieces of biometric authentication information included in the comparison group and the biometric information of the user acquired through the second terminal for performing the user authentication.
