Dynamic Authentication Adjusting Security Based on Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current user authentication schemes are cumbersome due to their reliance on static password requirements, failing to adapt to a user's context or environment, which can lead to unnecessary complexity and frustration.
Innovation Solution
A system and method that dynamically adjusts authentication requirements based on a user's context, using contextual information to assess risk and modify authentication rules, thereby reducing the burden on users by simplifying login processes when in secure environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static password authentication is used, then security requirements are maintained, but user convenience and login efficiency deteriorate
Solution Approach 1:
The patent implements dynamic authentication by adjusting authentication requirements based on real-time context factors such as device type, location, time, and user behavior patterns. The system transitions from static password verification to a dynamic challenge-response mechanism where authentication strength varies according to assessed risk levels, resolving the contradiction between maintaining security and improving user convenience.
Solution Approach 2:
The system changes authentication parameters (such as requiring additional verification factors or simplifying the process) based on contextual parameters like device recognition, geographic location, and time of access. By dynamically adjusting these parameters, the system maintains security for high-risk scenarios while providing streamlined access for low-risk situations.
2Ease of operation
If context-based dynamic authentication is implemented, then user convenience improves, but system complexity increases
Solution Approach 1:
The patent segments the authentication system into distinct modular components: context data collection modules, risk assessment engines, authentication challenge generators, and verification modules. This segmentation allows the complex system to be managed through independent, interchangeable components that can be selectively activated based on risk levels, reducing overall system complexity while maintaining dynamic capabilities.
Solution Approach 2:
The system performs preliminary context assessment and device registration before actual authentication occurs. By pre-evaluating device trustworthiness and user context in advance, the system prepares authentication challenges ahead of time, reducing the computational burden during actual login moments and simplifying the real-time authentication process.
3Ease of operation
If authentication requirements are reduced for familiar contexts, then user burden decreases, but security risk increases
Solution Approach 1:
The patent implements continuous feedback loops where the system monitors authentication outcomes, context changes, and security events in real-time. This feedback informs dynamic adjustments to authentication requirements, allowing the system to respond to emerging security risks by tightening requirements while maintaining simplified authentication for consistently verified low-risk contexts.
Solution Approach 2:
The system performs self-assessment of risk levels by automatically analyzing context data, device profiles, and user behavior patterns without requiring manual security configuration. This self-service capability allows the system to autonomously balance security and convenience, adjusting authentication requirements based on its own risk assessment rather than relying on fixed security policies.
Data Source
AI summary
A system and method and computer program product for user authentication that uses information about a user's context or context of their personal device(s) to dynamically modify that user's authentication or login requirements to an application in a computer or mobile device. The system is configured to run methods that detect and make use of a user's context that includes: a current environment or personal context, and uses this capability to enable variable strength authentication when attempting to log in or enter another application or resource. In one embodiment, the system implements methods to dynamically adjust the authentication challenge as a differential of all accumulated user contexts (e.g., providing a shorter password or pin-code).
