Location authentication using multispectral imaging
First Claim
Patent Images
1. A method for providing location authentication for a remote user in a network environment, comprising:
- displaying an authentication image on a display device located in a specific user location;
generating a captured image by the remote user when capturing the displayed authentication image using a client device, wherein the remote user is required to be physically within the specific user location for a visible display of the authentication image;
analyzing the captured image to determine a specific combination of color band values of selected pixels of the captured image;
generating a comparison result by comparing the color band values of the selected pixels of the captured image to color band values of corresponding pixels of the authentication image; and
granting the remote user to connect to a server for resource access when the comparison result is within a predetermined threshold so as to provide user location-specific authentication.

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 location authentication for a remote user in a network environment, comprising:
-
a display device, located in a specific user location, that displays an authentication image, wherein a client device is used by the remote user to generate a captured image by capturing the displayed authentication image, wherein the remote user is required to be physically within the specific user location for a visible display of the authentication image; a computer program executing on a hardware processor that analyzes the captured image to determine a specific combination of color band values of selected pixels of the captured image; a hardware processor programmed to generate a comparison result by comparing the color band values of the selected pixels of the captured image to color band values of corresponding pixels of the authentication image; and an authentication server that provides user location-specific authentication for granting the remote user to connect to a server for resource access when the comparison result is within a predetermined threshold. - View Dependent Claims (8, 9, 10, 11, 12)
