SHULDER-SURFING RESISTANT GRAPHICAL AUTHENTICATION METHOD AND SYSTEM USING TRANSPARENT MOVING SCHEME OF GRID AND IMAGE

摘要

In the present invention, images (including numerals and characters) are randomly displayed in a grid window, and symbols such as numerals and characters capable of specifying the position of the grid in the horizontal direction and in the vertical direction on the left and right sides A grid window with a mark is displayed, a screen is presented so that a user can input a password, a specific position of a grid displayed on the presented screen and a number of images are sequentially selected and registered as a password, A designated image which is randomly positioned with other images is moved to a designated position using a direction key, a touch pad, a mouse, a touch pan, a body part, etc. without directly touching the designated image, and the final position information of the moved image is recorded (I.e., password) of the registered moving image and the recorded moving position information, Using transparency of the grid moving method and the image including the step of processing the view difficult to steal We propose a graphic security authentication method and system.
