<p>This invention discloses an eye-positioning method for unlocking a pattern lock by a user, comprising: showing to the user a pattern diagram on a display, the pattern diagram being pre-stored in a storage device at a back-end server, and is transmitted to the display via a network; capturing a facial image of the user by a video-taking equipment coupled to the display; an on-screen marker real-time tracking an eye of the payer, enabling the marker to move on the pattern diagram to form a marker-movement path according to movement of the eye relative to the video-taking equipment, the eye being either a left eye or a right eye as pre-agreed; and determining if the marker-movement path includes an entirety of a pre-set action path. This invention also provides an electronic-payment authentication method using the aforementioned pattern-unlocking method, for payments at retail sites and for online payments.</p> |
