Method for registering and authenticating biometric data and electronic device thereof

Abstract

The present invention is for registering and authenticating biometric data in an electronic device, the electronic device including: a display including a touch sensor; a fingerprint sensor for acquiring fingerprint data through at least a partial region of the display region of the display; and a processor. Here, the processor can be set to: acquire first touch information from a first user input using the touch sensor, in response to the first user input for registering a fingerprint of a user; acquire first fingerprint data using the fingerprint sensor; register the first fingerprint data as fingerprint information based on the first touch information, the registering operation including an operation for classifying the first fingerprint data based on the first touch information; acquire second touch information from a second user input using the touch sensor, in response to the second user input for authenticating the fingerprint of the user; acquire second fingerprint data using the fingerprint sensor; select a candidate group for comparison from among the fingerprint information based on the second touch information; and compare fingerprint data included in the candidate group with the second fingerprint data.
