Object Alignment Challenges for Human-Bot Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems, such as CAPTCHA, are often bypassed by sophisticated agents, leading to unauthorized access and abuse of computer resources, causing frustration for legitimate users and failing to prevent automated abuse effectively.
Innovation Solution
An authentication challenge system that presents challenges requiring real-world experience and knowledge, using a combination of hardware and software components to differentiate between human and automated users, including a decision server, response processor, and challenge server to manage and evaluate user responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional CAPTCHA systems are used to block automated access, then unauthorized automated access is reduced, but legitimate users experience frustration and the system can be bypassed by sophisticated agents
Solution Approach 1:
The patent transforms the authentication challenge from traditional text-based CAPTCHA to a visual alignment task where users rotate objects to match reference orientations. This parameter change in challenge type maintains security while significantly improving user experience, as the alignment task is intuitive and satisfies most users within 2-3 attempts.
Solution Approach 2:
The patent replaces the mechanical/text-based verification system with a visual-spatial alignment system. Instead of requiring users to read and interpret distorted text, the system presents visual objects that users align by rotation, substituting one interaction paradigm for another that is both more secure against automation and more user-friendly.
2Reliability
If sophisticated authentication challenges are implemented to prevent automated abuse, then security against automated agents is improved, but system complexity increases
Solution Approach 1:
The patent divides the authentication system into three specialized components: a challenge server that generates and manages alignment challenges, a response processor that evaluates user submissions, and a decision server that determines access authorization. This segmentation allows each component to be optimized independently while working together to provide robust security.
Solution Approach 2:
The patent introduces an intermediary alignment challenge system between the user and the protected computer resource. This intermediary layer presents the alignment task that users must complete before accessing the resource, effectively mediating security verification without requiring complex multi-factor authentication or biometric scanning.
3Productivity
If automated processes are allowed to access computer resources, then productivity is improved, but unauthorized scraping and abuse increase
Solution Approach 1:
The alignment challenge system provides self-service authentication where users independently complete the alignment task without requiring human operator intervention or complex verification procedures. This maintains access efficiency for legitimate users while the automated nature of the challenge itself serves as a barrier to automated abuse, since sophisticated agents struggle to reliably solve the visual alignment task.
Data Source
AI summary
A system and method of computer challenge systems based on object alignment. The method includes generating a challenge data structure defining a challenge including a user interface to manipulate one or more objects to match a defined alignment. Generating the challenge includes adjusting, based on a risk of a user computer system, a number of possible combinations of the one or more objects by at least one of increasing a rotation axis of the one or more objects or reducing an angular increment associated with a control for the one or more objects. The method includes obtaining a user input to the user interface that represents a manipulation of the one or more objects to a first orientation. The method includes determining whether the first orientation of the one or more objects matches the defined alignment.
