METHOD FOR AUTHORIZING A USER USING A ELECTRONIC SIGNATURE IN A MOBILE TERMINAL

摘要

PURPOSE: A user authentication method using electronic signature in a portable terminal is provided to improve actual usage and a security level by identifying oneself through the comparison of two event time elements. CONSTITUTION: A controller receives the registration of an electronic signature of a user(201). The controller outputs a screen controlling a display unit and requests the input of a password(202). The controller compares the inputted password with the password saved in a storage unit(203). The user is requested of the selection of a sensor sensing a sign-up event(204). The controller stores selected sensor information in the storage unit(205). The controller controls the display unit and outputs a time bar(206). The controller confirms the input of a count start event(207). The controller receives the sign-up event from the selected sensors(208). The controller measures time to receive the sign-up event(209). The controller determines the termination of the measured time(210). The sign-up event and time of start-point and end-point are stored in the storage unit(211).
