SYSTEM AND METHOD FOR COMPUTER AUTHENTICATION USING AUTOMATIC IMAGE MODIFICATION

摘要

Computers can be authenticated using automatically combined images. During an authentication process, a server transmits an image to a client. The transmitted image is combined with a stored image using a randomly selected logical operator to generate a combined image. The combined image is transmitted back to the server. The server has a copy of the transmitted image and the stored image and generates a series of template combined images using different logical operators selected from a set of logical operators to determine whether any of the template combined images match the received combined image. If the received combined image matches one of the template combined images, the user is authenticated.

主权项

1. A system for authentication of a client computer and a server computer comprising:
a server computer communicatively coupled to an unauthenticated client computer via a network; a data storage structure associated with the server computer and configured to store first and second images; a network interface device associated with the server client computer and configured to transmit the first image to the unauthenticated computer via the computer network, the network interface device being further configured to receive an image from the unauthenticated client computer; and an image analyzer associated with the server computer and configured to analyze the image received from the unauthenticated client computer by combining the stored first and second images to thereby generate a combined image and to determine if the combined image matches the received image wherein the unauthenticated client computer is authenticated if the image analyzer determines that the received image matches the combined image.
