Abstract: The present disclosure provides an electronic device and system that include an electrode interface that can be brought in contact with the body of a user, a memory, and a processor operably coupled to the electrode interface and the memory, in which the processor is set to obtain user information through user authentication, generate a user authentication signal on the basis of the user information, and transmit the user authentication signal or a signal including at least a portion of the user authentication signal through the body of a user being in contact with the electrode interface.

Abstract: An electronic device and a method are provided. The electronic device includes a communication module, a touch screen display, a processor electrically connected with the communication module and the touch screen display, and a memory electrically connected with the processor. The memory is configured to stores an application program configured to transmit and receive data to/from an external electronic device using the communication module, and instructions to enable the processor to display a user interface of the application program in the touch screen display when the application program is executed. The user interface includes a first area that displays at least one of an image and text that is associated with a user who is related to the external electronic device, and a second area that displays data that is shared with the external electronic device, and the first area overlaps at least a part of the second area.
