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.

Claims

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.

2. The method as recited in claim 1, wherein the color band values are red, green, and blue RGB color component values.

3. The method as recited in claim 1, wherein the color band values include four or more values.

4. The method as recited in claim 1, wherein authentication includes providing a session certificate that enables the user to connect to a secure server.

5. The method as recited in claim 1, wherein the authentication image is changed after a predetermined time period.

6. The method as recited in claim 1, wherein the authentication image is changed after a random time period.

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.

8. The system as recited in claim 7, wherein the color band values are red, green, and blue RGB color component values.

9. The system as recited in claim 7, wherein the color band values include four or more values.

10. The system as recited in claim 7, wherein the authentication server provides a session certificate that enables the user to connect to a secure server when the comparison result is within the predetermined threshold.

11. The system as recited in claim 7, wherein the authentication image is changed after a predetermined time period.

12. The system as recited in claim 7, wherein the authentication image is changed after a random time period.
