CAPTCHA System Using Reputational Trust Scores to Reduce Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CAPTCHA systems rely solely on passive complexity for authentication, fail to incorporate reputational information, increase latency due to intermediary resource providers, and require frequent updates to accommodate new challenge formats, straining resource providers and compromising user satisfaction.
Innovation Solution
A computerized CAPTCHA system that determines a trust score based on reputational signals from user devices, dynamically selects challenges, and verifies users directly, reducing the burden on resource providers and enhancing security by leveraging preexisting user reputations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the resource provider serves as an intermediary between the user computing device and the CAPTCHA system, then the verification process can be supervised by the resource provider, but the communication latency increases and user satisfaction decreases
Solution Approach 1:
The patent extracts the intermediary function from the resource provider and assigns it to a dedicated CAPTCHA system. The resource provider simply embeds a CAPTCHA widget in the webpage, while the CAPTCHA system handles all verification communications directly with user devices, eliminating the resource provider as a communication intermediary and reducing latency.
Solution Approach 2:
The patent introduces a dedicated CAPTCHA system as a new intermediary specialized in verification tasks. This mediator handles all interactions with user computing devices directly, while the resource provider only provides the embedded widget, thus resolving the contradiction by creating a specialized intermediary that reduces overall system latency.
2Reliability
If the resource provider implements and supervises the verification process, then authentication can be controlled, but computing resources and security procedures must be maintained and updated frequently
Solution Approach 1:
The patent extracts the complex verification logic, challenge generation, and security management functions from the resource provider and consolidates them in a dedicated CAPTCHA system. The resource provider only needs to embed a simple widget, while the CAPTCHA system handles all complex authentication control tasks.
Solution Approach 2:
The patent creates a universal CAPTCHA system that provides multiple functions: generating challenges, verifying responses, managing security procedures, and adapting to new attack vectors. This multi-functional system eliminates the need for individual resource providers to maintain separate authentication infrastructures.
3Ease of manufacture
If the verification process relies solely on passive complexity of the CAPTCHA challenge, then implementation is simple, but the process is not dynamically tuned and reputational information is not incorporated
Solution Approach 1:
The patent implements dynamic verification by having the CAPTCHA system adjust challenge difficulty and type based on real-time analysis of user behavior, device characteristics, and reputational information. The system transitions from static fixed-difficulty challenges to adaptive dynamic challenges that respond to user context.
Solution Approach 2:
The patent incorporates feedback loops where the CAPTCHA system continuously analyzes user responses, device signals, and external reputational data to adjust verification strategies. The system learns from user behavior patterns and dynamically tunes challenge parameters based on this feedback.

AI summary
Systems and methods for verifying a user based on reputational information are provided. In particular, a computerized CAPTCHA system consisting of one or more computers can determine a trust score based on one or more reputation signals associated with a user computing device, select a challenge to provide to the user computing device based on the trust score, and determine whether to verify the user computing device based on a received response to the challenge and/or the trust score.
