Passcode Authentication System and Method with Colored Light Feedback

Abstract

A passcode authentication system and method are disclosed, wherein color display is used instead of alpha numeric displays. The passcode authentication system according to the current invention includes a LED color display unit to identify the code entered by a user. This provides a feedback to indicate a code selected. A single or plurality of buttons are used to select a sequence of colors, wherein the sequence of colors is converted to a sequence of digital codes. An example of color code set is; Red, Green, Blue, Cyan, Magenta, Yellow, and White, but the color code size can be changed by removing or adding additional unique colors as necessary. A user can memorize the passcode as a sequence of colors as well as numbers utilizing a simple mapping. This makes the passcode authentication system low cost and allows for a small form factor design since neither keypad nor screen/numeric display devices are required.

Dependencies are inferred from the claim text.
