Abstract

The present invention relates to a keyless entry system that contains a visual random code generator so that the possible input pattern is different every time a user accesses the system. A keypad device containing an input device and a display are electronically connected to a processor containing the visual random code generator. Positions and associated values are displayed on the input device, such as a touch sensitive screen, allowing the user to enter an access code. The visual random code generator randomizes and controls the input pattern displayed so that the input pattern changes each time the system is accessed.

Claims

1. A visual random code system comprising:

a. an input device; and

b. a visual random code generator capable of randomizing a plurality of values associated with a plurality of input device positions.

2. The system of claim 1, wherein said input device positions are displayed on a touch screen.

3. The system of claim 1, wherein said visual random code generator randomizes a plurality of values of numbers, letters, colors, words or symbols displayed on said input device positions.

4. The system of claim 2, wherein said visual random code generator is capable of randomizing the positioning of said plurality of input device positions on said touch screen.

6. The method of claim 4, wherein said system is selected from a group consisting of automobile lock, garage door, residential door, office door, classified area entrance, computer system, and automatic teller machine.

5. A method for entry control into a system comprising the steps of

a. randomizing a plurality of values on a plurality of input device positions;

b. accepting a code input from a user, wherein said code input is based on the user'"'"'s selection of said values; and

c. allowing entry into said system if said selection of said values is the same as a predetermined required access code.

7. The method of claim 5, wherein said input device positions are displayed in a touch screen.

8. The method of claim 5, wherein said input device positions use a plurality of solid state switches or capacitive devices.

9. The method of claim 5, wherein said input device positions and said values are a pattern of numbers, letters, colors, words, or symbols.

10. A visual random code system comprising:

a keypad display with a touch-sensitive input screen;

a processor for randomizing the values for a plurality of graphic positions for displaying on said input screen,

wherein said processor receives user input from said input screen and compares said user input with a stored required access code to determine if access should be granted.

11. The system of claim 10, wherein said processor randomizes a plurality of values of numbers, letters, colors, words or symbols displayed on said graphic positions of said keypad.

12. The system of claim 10 wherein said processor starts a pre-determined action if said input matches said pre-determined required access code.

13. The system of claim 10, wherein said processor is capable of randomizing the positioning of said plurality of graphic positions on said touch-sensitive input screen.
