There is provided a forged fingerprint identification method. The method comprises obtaining a first fingerprint image for a fingerprint for an input finger of a target user at a first position; obtaining a second fingerprint image for the fingerprint for the input finger of the target user at a second position; and determining whether the fingerprint of the target user is a forgery based on a result of comparison of a result of fingerprint comparison between the first fingerprint image and the second fingerprint image with predetermined threshold conditions.

Forged fingerprint identification method and forged fingerprint identification apparatus, and storage medium storing instructions to perform forged fingerprint identification method

A method for registering a fingerprint of a user through an electronic device, comprising: sensing a fingerprint input into a fingerprint recognition area formed on a display module of the electronic device to capture at least one image of the fingerprint input; determining characteristics of the fingerprint input based on the at least one image of the fingerprint input when the fingerprint input is a rolled fingerprint; and storing the at least one image of the fingerprint input and the characteristics of the fingerprint input as personalized information of the user.

Electronic device and method for registering and authenticating fingerprint

A method of determining a counterfeit fingerprint by a system for determining a counterfeit fingerprint that includes an internal light source and an external light source, comprising: extracting a first fingerprint area of a first fingerprint image obtained from a light signal of the internal light source when a target object's fingerprint comes in contact with a fingerprint contact surface of the system for determining a counterfeit fingerprint; extracting a second fingerprint area of a second fingerprint image obtained from a light signal of the external light source based on the first fingerprint area; and inputting the first fingerprint area and the second fingerprint area into a pre-trained neural network of the system for determining a counterfeit fingerprint to output a result of determining whether the fingerprint is counterfeit.
