LOCATION AUTHENTICATION USING MULTISPECTRAL IMAGING
First Claim
1. A method for providing authentication in a network environment, comprising:
- displaying an authentication image on a display device;
generating a captured image by capturing an image using a client device;
analyzing the captured image to determine color band values of selected pixels of the captured image;
generating a comparison result by comparing the color band values the selected pixels of the captured image to color band values of corresponding pixels of the authentication image; and
providing authentication when the comparison result is within a predetermined threshold.

Abstract
An invention is provided for authentication in a network environment. The invention includes displaying an authentication image on a display device, and generating a captured image by capturing an image using a client device. The captured image then is analyzed to determine color band values of selected pixels of the captured image. Once analyzed, a comparison result is generated by comparing the color band values the selected pixels of the captured image to color band values of corresponding pixels of the authentication image. If the comparison result is within a predetermined threshold authentication is provided.

7. A system for providing authentication in a network environment, comprising:
-
a display device that displays an authentication image, wherein a client device is used to generate a captured image by capturing an image; a computer program executing on a processor that analyzes the captured image to determine color band values of selected pixels of the captured image; a processor programmed to generate a comparison result by comparing the color band values the selected pixels of the captured image to color band values of corresponding pixels of the authentication image; and an authentication server that provides authentication when the comparison result is within a predetermined threshold. - View Dependent Claims (8, 9, 10, 11, 12)
