The objective of this invention is to protect the information entry such as a PIN from theft by observation of the finger movement based on the conventional fixed arrangement of entry keys. The present invention is an information entry system comprising a touch panel monitor screen, wherein the touch panel monitor screen displays keys for information entry, which are arranged circularly in order and rotates around the center of the circular arrangement without changing the order when a user touches a predetermined option key. This system also have a central processing unit and a program storage unit including an Information entry Screen Generator, a Random Number Generator, a Key Moving Unit, and an PIN Information output unit. This information entry device prevents a PIN or any other information entry from being stolen by someone who glances at the finger movement, since the entire series of the entry keys are rotated before or after the PIN entry. The information entry system of the present invention can be adapted for an ATM or PDA terminal as well as for a touch panel screen monitor.
