METHODS AND SYSTEMS FOR PROTECTING WEBSITE FORMS FROM AUTOMATED ACCESS

摘要

Systems and methods to tell apart computers and humans using image recognition task having a dynamic graphical arrangement of randomly selected images. The images can be arranged as a grid or matrix for presentation on a device display for authentication of a user as human. The kinds of graphical images can be derived from a selected category for the image recognition task. A series of randomly generated access codes corresponding to the images can be displayed with the images. The user may enter the access codes corresponding to images from the selected category. An authentication server can compare the access code entry to an authentication reference code corresponding to the particular arrangement of images. The selection of images, their arrangement and their corresponding access codes, may dynamically change in between verification sessions.

主权项

1. A method in a computing system for providing secure transactions, the method comprising:
receiving from a client a request to perform a transaction; creating a transaction verification page comprising information regarding the transaction, the transaction verification page comprising a dynamic graphical arrangement of randomly selected images, the transaction verification page requesting the user to select at least one image from a selected category of images chosen for an image recognition task to commit the transaction; transmitting the transaction verification page to the client; receiving an image selection from the client, the image selection being input to the transaction verification page by the user; in response to the image selection matching the randomly selected image from the selected category, committing the transaction represented by the transaction verification page; and in response to the image selection not matching the randomly selected image from the selected category, aborting the transaction represented by the transaction verification page.
