PROBLEM TO BE SOLVED: To provide a method and a device, etc., for protecting key input from malware.SOLUTION: Coordinates of a place at which a user touches a touch panel 10 are sent to a security engine 12 as unprocessed coordinates. The security engine 12 determines whether or not touch panel input is inputted within the secure area of the current display of the touch panel, and when it is determined that the touch panel input is included in the secure area, a shuffled touch event is outputted to a driver 16. The driver 16 gives the data to a non-trusted code 22, and a website server having received the touch event decodes the key event. A touch panel input not reaching the secure area is routed directly to an operating system driver 20 via a path 18.SELECTED DRAWING: Figure 1 |
