Abstract
A mechanism for allowing a user to prove their identity on touch-based devices employing the use of a touch surface in firmware-controlled environments is discussed. The user may prove his or her identity by entering a series of strokes on the touch-based device to form a word or image. Characteristics of the entered strokes such as stroke order and stroke direction are compared to stored stroke characteristics that were gathered from a drawing of the same word or image during a user enrollment process. If the stroke characteristics comparison is acceptable, the user identity is verified.
