ENCRYPTING TOUCH-SENSITIVE DISPLAY |
摘要 |
A hardware encryption device comprises: a touch panel controller; and a cryptographic engine in communication with the touch panel controller. The touch panel controller receives co-ordinates from the cryptographic engine corresponding to an area on a touch panel selected by a user. The cryptographic engine is operable to discriminate between a selection in a secure area on a screen and a selection in a non-secure area on a screen, and to action the selection differently depending on whether the selection is in a secure area or a non-secure area.
