Abstract: Various embodiments of the disclosure relate to an electronic device for determining a matching model used to authenticate biometric information, and an operating method thereof. An electronic device according to various embodiments of the disclosure may include a biometric sensor, and a processor operatively coupled with the biometric sensor. The processor may be configured to identify a security level of a service requested to be executed, determine a confidence level of user's biometric data received via the biometric sensor, determine a matching model to be used to authenticate the received user's biometric data based on the identified security level and the determined confidence level, and authenticate the received user's biometric data based on the determined matching model. Various other embodiments are also possible.

Abstract: Provided is a liveness verification method and device. A liveness verification device acquires a first image and a second image, and select one or more liveness models based on respective analyses of the first image and the second image, including analyses based on an object part being detected in the first image and/or the second image, and to verify, using the selected one or more liveness models, a liveness of the object based on the first image and/or the second image. The first image may be a color image and the second image may be an Infrared image.

Abstract: An electronic device for acquiring biometric information may include a display, and a fingerprint sensor configured to acquire fingerprint data through at least a partial display region of the display. A processor may execute a first application in which a graphical object is displayed, for controlling a designated function other than a fingerprint registration function. A user input on the graphical object may be used to collect fingerprint information, which is used as part of a fingerprint registration function.
