Abstract
A method for authenticating capacitive touch, executed through a system interworking with a capacitive touch screen supporting multi-touch, comprises receiving touch point information for touch points recognized as multi-touch through the capacitive touch screen, reading the touch point information and identifying a specified touch point corresponding to any one specified touch portion fixed and arranged in a previously specified position in design among touch portions of a touch device in which capacitively touchable touch portions are arranged according to a previously designed unique geometric relationship, coordinate-rotating the touch points or a geometric relationship for the touch points to match a designed geometric relationship based on a reference point corresponding to the specified touch point, and authenticating whether the coordinate-rotated geometric relationship matches the designed geometric relationship within a tolerance range or identifying the designed geometric relationship matching the coordinate-rotated geometric relationship within a tolerance range among the designed geometric relationships.
