Interactive CAPTCHA

Abstract

The present disclosure involves a method. The method includes receiving a request from a user. The method includes constructing, by a computer processor, a media object that contains a plurality of media components. The method includes transmitting the media object to the user. The method includes prompting the user to perform a task involving at least a subset of the media components, the task including at least one of the following: selecting each of the media components in the subset according to a predefined sequence; and modifying at least one of the media components in the subset with respect to at least one of its following properties: location, size, appearance, and orientation. The method includes obtaining a description of an action performed by the user in response to the prompting. The method includes deciding whether or not to grant the request based on the obtaining.

Description

BACKGROUND[0001]1. Technical Field[0002]The present disclosure generally relates to computer security, more particularly, to a more secure and user friendly CAPTCHA.[0003]2. Related Art[0004]Online transactions are becoming more and more prevalent, with an ever-increasing number of online entities that may or may not have a physical real world counterpart. Furthermore, the services offered by these online entities have been improving as well. The popularity of online transactions is partially attributable to the ease and convenience of making a transaction online instead of at a physical location. As more and more transactions are done online, fraud prevention becomes critical. Among other methods, one method of detecting potential fraud is to check to see if a user is really a human being or a machine. This type of detection is known as CAPTCHA, which stands for “Completely Automated Public Turing Test to tell Computers and Humans Apart.”[0005]A conventional CAPTCHA may involve dis...

AI Technical Summary

Benefits of technology

The patent discloses a method, apparatus, and system for receiving a user's request, constructing a media object with multiple media components, and prompting the user to perform various tasks involving the components. The tasks include selecting and modifying the components based on their properties like location, size, appearance, and orientation. The system also obtains a description of the user's actions and decides whether to grant or not the request based on that description. The technical effects of this patent are improved user experience and more efficient media object construction and modification.

Problems solved by technology

However, rapid advances in computer technology has made computers much more capable of solving CAPTCHAs, which means conventional CAPTCHAs may not offer as much reliability as they once did.

In addition, traditional CAPTCHAs may be difficult for humans to correctly identify as well, particularly if the display is on a small screen such as a mobile telephone screen.

Consequently, a human user could be erroneously classified as a machine, which defeats the purpose of the CAPTCHA.

Therefore, while existing CAPTCHAs have been generally adequate for their intended purposes, they have not been entirely satisfactory in every aspect.
