<p>The present invention provides a method for multi-touch authentication using a touch device. In a method of providing a value using a touch device performed through an operating server communicating with a wireless terminal having a capacitive touch input unit which supports multi-touch, a component value calculated through a program of the wireless terminal is received in order to authenticate whether a multi-touch characteristic including at least one geometric relationship among distances and angles of a plurality of touch points recognized by multi-touch through a capacitive touch input unit of the wireless terminal is matched with a touch characteristic of a specific touch device among touch devices manufactured by arranging a plurality of touch units including a material allowing capacitive touch according to a previously designed geometric relationship. An authentication procedure is performed to authenticate whether the multi-touch characteristic including the geometric relationship between the touch points detected based on the component value is matched with a multi-touch characteristic including a design geometric relationship among a plurality of touch units included in the specific touch device. An authentication result made through the authentication procedure is processed to be provided to a program of the wireless terminal.</p> |
