Abstract: Provided are a method of recognizing a fingerprint and a device including the same. The method of recognizing a fingerprint includes obtaining a fingerprint image from a fingerprint sensor, determining whether a pixel in the fingerprint image is defective based on a dispersion value of the pixel with respect to time, in response to determining that the pixel is defective, generating an interpolated pixel value of the pixel by performing interpolation on a first pixel value of the pixel based on a second pixel value of another pixel different from the pixel, and correcting the fingerprint image based on the interpolated pixel value.

Abstract: A fingerprint verification method and apparatus is disclosed. The fingerprint verification method may include obtaining an input fingerprint image, determining a matching region between the input fingerprint image and a registered fingerprint image, determining a similarity corresponding to the matching region, representing a determined indication of similarities between the input fingerprint image and the registered fingerprint image, relating the determined similarity to the matching region as represented in a matching region-based similarity, determining a result of a verification of the input fingerprint image based on the matching region-based similarity, and indicating the result of the verification.

Abstract: An electronic device is disclosed. The disclosed electronic device comprises: a touch screen display structure; a first wireless communication circuit; a second wireless communication circuit; a stylus pen including at least one button which can be pressed or touched; a processor operationally connected to the touch screen display structure and the first wireless communication circuit; and a memory operationally connected to the processor. A first application program including a first user interface, and a second application program including a second user interface are stored in the memory. The memory has instructions stored therein which are configured to cause, when executed, the processor to: execute the first application program and second application program when a user input is received; display at least one of the first user interface and second user interface by means of the touch screen display structure; receive a first signal, which is generated by the press or touch of the button for a first time period, from the stylus pen through the first wireless communication circuit; select one from the first application program and second application program on the basis of the first signal; change at least part of information displayed on the screen, at least partly on the basis of the selection; receive a second signal, which is generated by the press or touch of the button for a second time period different from the first time period, from the stylus pen through the first wireless communication circuit; and at least partly on the basis of the selection, perform a function of the first application program or a function of the second application program in response to the second signal. Various other embodiments are possible.

Abstract: A fingerprint verification method and a fingerprint verification apparatus performing the fingerprint verification method are disclosed. The fingerprint verification apparatus determines a first similarity between a query fingerprint image and each of registered fingerprint images, selects a target registered fingerprint image group from registered fingerprint image groups based on the first similarity, determines a second similarity between the query fingerprint image and each of registered fingerprint images in the target registered fingerprint image group based on matching relationship information between the registered fingerprint images in the target registered fingerprint image group, and determines whether fingerprint verification of the query fingerprint image is successful based on the second similarity.
