Risk-Based Authentication System for Adaptive Security Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems are inefficient and inconvenient, as they often require repeated authentication from users and devices, especially when accessing protected services, which can be unnecessary for low-risk scenarios, thereby compromising user experience and security.
Innovation Solution
Implementing a risk-based decision-making system that captures user and device attributes to determine the security risk, allowing for reduced or eliminated additional authentication when the risk is deemed acceptable, thereby enhancing the efficiency and security of the authentication process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repeated authentication is required for all access attempts, then data security is improved, but user convenience and productivity deteriorate
Solution Approach 1:
The system changes the authentication parameters dynamically based on risk assessment. Instead of using a fixed authentication requirement for all access attempts, the system adjusts the authentication level (from none to additional authentication) based on risk factors such as device trust level, location, and access pattern anomalies. This resolves the contradiction by making security measures adaptive rather than static.
Solution Approach 2:
The authentication system transitions from a static, one-size-fits-all approach to a dynamic risk-based approach. The system continuously monitors access patterns and device characteristics, adjusting authentication requirements in real-time based on the assessed risk level. This dynamic adaptation allows the system to maintain security while improving user convenience for low-risk scenarios.
2Reliability
If additional authentication steps are required for all access attempts, then data security is improved, but authentication time and productivity deteriorate
Solution Approach 1:
The system changes authentication parameters based on risk assessment results. For low-risk access attempts, the system parameters indicate no additional authentication is needed, allowing immediate access. For high-risk attempts, the system switches to requiring additional authentication steps. This parameter adaptation optimizes authentication efficiency while maintaining security.
Solution Approach 2:
The system applies partial authentication action only when necessary. Instead of requiring full authentication for all access attempts, the system performs risk assessment first and only applies additional authentication steps when the risk level justifies it. This partial action approach eliminates unnecessary authentication overhead for low-risk scenarios while maintaining security for high-risk scenarios.
3Device complexity
If standard authentication systems are used without risk-based decisions, then system simplicity is maintained, but security optimization and adaptability deteriorate
Solution Approach 1:
The system introduces a risk assessment intermediary component that sits between the access request and the authentication decision. This intermediary analyzes risk factors and provides a recommendation that influences the authentication outcome. By adding this intermediary layer, the system achieves security optimization without fundamentally redesigning the entire authentication architecture, thus balancing complexity and security improvement.

AI summary
Embodiments of the disclosure provide a method for enhancing standard authentication systems to include risk-based decisions. Risk-based decisions can be selectively implemented within existing authentication systems to strategically modify and supplement security if an unacceptable risk is detected. Embodiments capture information pertaining to a user and user device. Information is stored to create a profile for the user and user device. A comparison between the stored information and live data can be performed within authentication systems to optimize security. If the results of the comparison demonstrate the presence of an acceptable risk, then the need for subsequent authentication can be reduced or eliminated, which improves a user experience.
