Abstract

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 the keys are rotationally shifted by a random number of key units around the center of the circular arrangement without changing the order when a user touches a predetermined option key before or after the information entry. This system also has a central processing unit and a program storage unit including an Information entry Screen Generator, a Random Number Generator, a Key Moving Unit, and a 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.

Claims

1. An information entry system having a display unit, a memory, and a controller, said controller comprising:

Information entry screen generator for generating an entry screen on said display, the entry screen including a plurality of entry keys and a scramble key;

Random number generator for generating a random number when a user touches the scramble key on said display unit, and for storing the random number in said memory;

Key moving unit for moving each of the plurality of entry keys on the display unit based on the random number stored in the memory; and

Information output unit for receiving the user'"'"'s entry key information created as the user selectably touches at least one of said scrambled entry keys on the display unit, and outputting said information.
