Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication methods are inadequate in providing flexible and dynamic security measures, particularly in online financial transactions, leading to user dissatisfaction and increased risk of fraud.
Innovation Solution
A system that categorizes financial interactions into tiers based on risk levels and assigns respective authentication policies, activating security challenges at user devices to ensure secure transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods (passwords, credentials) are used, then implementation is simple, but security reliability is insufficient and vulnerable to fraud
Solution Approach 1:
The patent implements dynamic authentication by continuously monitoring device behavior, transaction patterns, and risk indicators to adjust authentication requirements in real-time. The system transitions from static password-based authentication to a dynamic multi-factor approach that adapts security measures based on current risk assessments, thereby improving reliability without requiring permanently complex systems.
Solution Approach 2:
The authentication system is segmented into multiple independent verification layers including device identification, user credentials, behavioral analysis, and risk assessment modules. Each segment operates semi-independently, allowing the system to activate only the necessary authentication tiers based on transaction risk, thus improving security while managing complexity through modular design.
2Reliability
If strong authentication measures are applied to all transactions, then security reliability improves, but user convenience deteriorates due to frequent security challenges
Solution Approach 1:
The system applies different authentication qualities to different transactions based on their specific risk characteristics. Low-risk transactions (e.g., viewing account balance) require minimal authentication, while high-risk transactions (e.g., large wire transfers) trigger enhanced security challenges. This localized application of security measures protects against fraud while maintaining user convenience for routine operations.
Solution Approach 2:
The authentication requirements are dynamically adjusted by changing parameters such as risk thresholds, challenge frequency, and verification strength based on transaction characteristics, device trust levels, and behavioral patterns. This allows the system to optimize the balance between fraud protection and user convenience by adapting security parameters to each specific transaction context.
3Reliability
If continuous monitoring and evaluation of interactions are implemented, then fraud detection capability improves, but system complexity and processing time increase
Solution Approach 1:
The system performs preliminary authentication and risk assessment actions before the actual transaction processing. Device identification, credential verification, and initial risk scoring are completed in advance, allowing the main transaction to proceed quickly once authorized. This preliminary action reduces the time penalty of continuous monitoring by front-loading the security checks.
Solution Approach 2:
For low-risk transactions from trusted devices with established user profiles, the system skips detailed behavioral analysis and risk evaluation steps, rushing through the authentication process with minimal verification. This selective skipping maintains high fraud detection accuracy for suspicious transactions while minimizing processing time for routine operations.

AI summary
Provided is dynamic and flexible authentication based on an interaction over a communications link between a user device and a financial entity. A set of interactions enabled at the user device are categorized into different levels, each level comprises a different authentication policy. At about the same time as an interaction is initiated at the device, an authentication policy assigned to the interaction is accessed and a security challenge is activated at the device. Based upon a successful response to the security challenge, an enablement of the communications link is continued. Based upon an unsuccessful response to the security challenge, the communications link is disabled.
