Abstract
A display apparatus includes an input section that inputs input information representing an input operation from an operation means contacting a touch screen, a display section that refers to an authentication table correlating the input operation with a display image so as to display the display image on the touch screen, and an authentication processing section that refers to the authentication table so as to determine whether or not a combination of a display image displayed on the touch screen and an input operation represented by the input information input by the input section in a state where the display image is being displayed is correlated in the authentication table, and authenticates an input action by the input operation when the combination is correlated in the authentication table.
