AN INPUT, RECEIVING DEVICE FOR MESSAGE INPUT USING MOBILE DEVICE, AND INPUT METHOD FOR PASSCODE USING THE SAME

摘要

PURPOSE: Message input, a receiving apparatus for the message input using a mobile device, and a password input method using the same are provided to greatly improve security by separately performing password input to the mobile device and the exposure of a password to the outside. CONSTITUTION: An input unit(100) receives messages such as a password and a command. A calculation unit(110) codes inputted message to a magnetic field on-off pattern according to defined regulation. A control unit(120) controls generation of a magnetic field according to the coded magnetic field on-off pattern. A magnetic field generation unit(130) is controlled by the control unit. The magnetic field generation unit generates the magnetic field.
