Abstract
At the time of input of authentication information, even when the hand and the input screen are seen from the third person, guess of authentication information is made difficult. A plurality of keys serving as input means are divided into a first region and a second region. Then, the first region and the second region are caused to transit between a first state and a second state distinguished from each other depending on the displayed contents. When a region where a key to be inputted for the input of authentication information is arranged is in the second state, input to the above-mentioned plurality of keys is recognized as dummy.
