Text-Reading Test Authentication for Automated Attack Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication methods, such as two-step authentication and smart cards, are cumbersome, resource-intensive, and unable to effectively prevent phishing, Man-in-the-Middle (MITM), and Man-in-the-Browser (MITB) attacks, which pose significant risks in online transactions by allowing unauthorized access and data tampering.
Innovation Solution
Implementing a Text-Reading Test (TRT) that uses distorted text embedded in images or audio-visual presentations, which can only be deciphered by humans, to authenticate users by requiring them to recite or confirm the content, thereby distinguishing human users from automated programs and ensuring secure communication channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two-step authentication or smart card methods are used, then security against automated attacks is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent replaces complex mechanical/authentication hardware systems (smart cards, tokens) with a software-based Turing test mechanism that uses distorted text images and audio presentations. This substitution maintains security reliability while eliminating the need for additional physical authentication devices, thereby reducing device complexity.
Solution Approach 2:
The authentication system performs self-verification by presenting distorted text or audio that only human users can interpret. The system automatically compares user responses with expected answers, eliminating the need for manual verification steps or additional authentication hardware, thus simplifying the overall authentication process while maintaining security.
2Reliability
If out-of-band communication is used for transaction confirmation, then security is improved, but loss of time and productivity worsen
Solution Approach 1:
The patent merges the transaction confirmation process with the authentication process by integrating the Turing test directly into the transaction flow. Users verify transaction details and authenticate simultaneously through the distorted text/audio challenge, eliminating the need for separate out-of-band communication steps and reducing time loss while maintaining security.
Solution Approach 2:
The system performs preliminary authentication verification through the Turing test before the actual transaction is processed. By validating user humanity and intent in advance through the distorted text/audio challenge, the system prevents fraudulent transactions without requiring time-consuming post-transaction verification steps.
3Ease of operation
If traditional authentication methods are used, then ease of operation is maintained, but object-generated harmful factors worsen due to vulnerability to phishing and MITM attacks
Solution Approach 1:
The patent introduces a Turing test intermediary mechanism that sits between the user and the authentication system. This intermediary presents distorted text or audio challenges that verify human users while automatically blocking automated attacks. The mechanism maintains ease of operation for legitimate users (who can naturally interpret the distorted content) while eliminating vulnerability to phishing and MITM attacks by preventing automated bot participation.

AI summary
System and methods for authenticating a transaction between a user system and a host system are described herein. In one embodiment, the system and methods use a text-reading test (TRT) image as part of the authentication process. The TRT image is presented to the user upon initiation of a transaction by the user. Information provided by a user, via the user system, after perception of the TRT image is compared to the source information in the TRT image. If the user input corresponds to the source information, the user is authenticated and transaction is allowed to proceed.
