    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 processor fingerprint enrollment method and apparatus is disclosed. A processor implemented fingerprint enrollment method includes performing a matching between a received input fingerprint image of a user and one or more enrolled fingerprint images, and selectively, based on a result of the matching identifying a matched enrolled fingerprint image from the one or more enrolled fingerprint image and based on a calculated degree of diversity in the fingerprint corresponding to an overlapping region between the input fingerprint image and the matched enrolled fingerprint image, storing the input fingerprint as another enrolled fingerprint image.
