Abstract: An electronic device, including a touch recognition unit; a display unit receiving a signal from the touch recognition unit; a fingerprint recognition unit receiving a signal from the display unit. A processor is configured to transmit and receive a signal to/from the touch recognition unit, the display unit, and the fingerprint recognition unit. The processor may remain in an inactive state while the touch recognition unit, display unit, and fingerprint recognition unit are activated. The processor is activated when a preset user's fingerprint input is provided. A method operates the electronic device.
