Adaptive User Authentication via Risk-Based Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user authentication systems are inadequate in balancing fraud prevention with customer experience, as they rely on static identity data and fail to adapt to complex customer behavior, leading to increased friction and inefficiencies in digital transactions.
Innovation Solution
An adaptive user authentication system that employs a risk-based approach using digital identity intelligence, implementing a sequence of authentication steps including numerical verification, live image analysis, and passport verification, with the ability to pause and resume identity verification and schedule human intervention, to verify user identity dynamically based on risk scores.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static identity data verification is used, then implementation is simple, but fraud prevention capability is insufficient
Solution Approach 1:
The authentication system dynamically adapts its verification process based on real-time risk assessment. Instead of using a fixed authentication flow, the system adjusts the sequence and type of verification steps (e.g., selecting between biometric challenges, out-of-band challenges, or document verification) based on the calculated risk score of each authentication request, making the system both more secure and context-appropriate
Solution Approach 2:
The system changes the parameters of authentication verification based on risk levels. Low-risk requests undergo minimal verification to maintain customer experience, while high-risk requests trigger enhanced verification protocols including multiple authentication factors and human review, thereby adjusting the security parameter dynamically rather than using a static approach
2Reliability
If enhanced authentication verification is implemented, then fraud prevention is improved, but customer experience deteriorates due to increased friction
Solution Approach 1:
The system applies different levels of verification quality to different authentication requests based on their risk profiles. Low-risk requests receive minimal verification (fast track), while high-risk requests receive enhanced verification (human review, multiple factors). This localized approach ensures that enhanced security is applied only where necessary, preserving customer experience for legitimate users while maintaining strong fraud prevention
Solution Approach 2:
The authentication flow dynamically adjusts its complexity based on real-time risk assessment. The system evaluates multiple factors (device fingerprint, location, behavior patterns, request amount) and adapts the verification sequence accordingly, ensuring that customers experience minimal friction when risk is low but receive appropriate security scrutiny when risk indicators are present
3Ease of operation
If risk-based adaptive authentication is implemented, then customer experience for low-risk users is improved, but system complexity increases
Solution Approach 1:
The authentication system segments requests into different risk categories (low-risk, medium-risk, high-risk) based on evaluation of multiple factors including device fingerprint, geographic location, behavioral patterns, and transaction amount. Each segment receives an appropriate verification level, allowing the system to manage complexity through structured categorization while providing optimized experiences for each segment
Solution Approach 2:
The system introduces a risk assessment intermediary layer that evaluates authentication requests before routing them to appropriate verification processes. This intermediary analyzes multiple data points and determines the appropriate authentication flow, thereby managing system complexity through a centralized decision-making layer rather than requiring complex logic throughout the entire system

AI summary
An adaptive user authentication system is disclosed that executes user authentication by verifying user identity using different authentication steps based on a risk score. The risk score enables determining if the requesting user's identity is to be verified. If it is determined that the user identity is to be verified, a sequence of authentication steps is implemented wherein more and more data is collected regarding the user as the user fails to be authenticated at each of the authentication steps. A first authentication step includes a numerical-based authentication step followed by a second authentication step including a live image authentication. If the user fails to be authenticated at either the first or the second authentication steps then a third authentication step to verify the user's passport is implemented.
