Abstract
An apparatus and a method for managing security of a terminal which increases reliability of an electronic signature. The apparatus includes a controller for detecting coordinate values of input positions of an electronic pen as interruption information when the interruption is received, and a memory for storing the detected input positions as additional electronic signature information.
Claims20
An apparatus for managing security of a terminal, the apparatus comprising:
- a touch screen configured to receive inputs from an electronic pen;
- a memory;
- and
- a controller configured to:
- receive and display an electronic signature generated by the electronic pen through the touch screen,
- after the electronic signature is displayed, detect coordinate values generated by a trace of the electronic pen over at least a portion of the displayed electronic signature while an interruption is received by activation of a button of the electronic pen,
- store, in the memory, the electronic signature and the coordinate values as interruption information, the interruption information utilized as additional electronic signature information for authentication, and confirm the electronic signature as authenticated when the detected coordinate values match a prestored sub-portion of the electronic signature, a starting point (a1) of the prestored sub-portion being different than a starting point of the electronic signature, and the starting point (a1) being different than an ending point (b1) of the prestored sub-portion,
- wherein the interruption is transmitted by the electronic pen when the button is pressed, and
- wherein a starting point of the displayed electronic signature is different than a starting point of the prestored sub-portion (a1), and an ending point of the displayed electronic signature is different than an ending point of the prestored sub-portion (b1), and the starting point of the prestored sub-portion (a1) is different than the ending point of the prestored sub-portion (b1).

A method of managing security of a terminal, the method comprising:
- detecting and displaying, via a touch screen, an electronic signature generated by an electronic pen;
- after the electronic signature is displayed, detecting coordinate values generated by a trace of the electronic pen over at least a portion of the displayed electronic signature while an interruption is received by activation of a button of the electronic pen;
- and
- storing, in a memory, the electronic signature and the coordinate values as interruption information, the interruption information utilized as additional electronic signature information for authentication, confirming the electronic signature as authenticated when the detected coordinate values match a prestored sub-portion of the electronic signature, a starting point (a1) of the prestored sub-portion being different than a starting point of the electronic signature, and the starting point (a1) being different than an ending point (b1) of the prestored sub-portion,
- wherein the interruption is transmitted by the electronic pen when the button is pressed, and
- wherein a starting point of the displayed electronic signature is different than a starting point of the prestored sub-portion (a1), and an ending point of the displayed electronic signature is different than an ending point of the prestored sub:
- portion (b1), and the starting point of the prestored sub-portion (a1) is different than the ending point of the prestored sub-portion (b1).
