An apparatus and method for securing user input data in an electronic device including an input interface. A touch panel senses touch events in an input interface, a touch integrated circuit receives coordinate data associated with the touch events and encrypts the coordinate data using a secure key. The touch integrated circuit blocks a main processor of the electronic device from being aware that a touch event has been sensed and may directly transmit the coordinate data to a server without the intervention of the main processor. |
