Adaptive Authentication Control for Space-Reliant Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional authentication schemes in mobile environments face a trade-off between security and convenience, with increased exposure to security threats necessitating a solution that balances both factors.
Innovation Solution
An authentication scheme that adapts based on the reliability of the authentication-processing space, determined by the correlation between the user and other users who visit the same space, using a weighted value system to adjust authentication requirements, such as omitting additional authentication within a certain distance and time after successful authentication in high-reliability spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication schemes (ID/password, OTP, certificate) are used to improve security, then security is improved, but convenience deteriorates
Solution Approach 1:
The patent applies dynamics by making the authentication scheme flexible and adaptable rather than static. The system dynamically selects authentication methods based on the determined space reliability, transitioning between different authentication levels (first, second, third schemes) according to environmental trustworthiness. This resolves the contradiction by allowing strong authentication only when necessary while providing convenient access in trusted environments.
Solution Approach 2:
The patent changes the parameter of authentication requirement based on space reliability parameters. By calculating space reliability scores and comparing them against threshold values, the system adjusts authentication stringency accordingly. This parameter-based adaptation allows the system to maintain security standards while reducing unnecessary authentication friction in high-trust spaces.
2Reliability
If authentication requirements are increased to improve security, then security is improved, but productivity deteriorates
Solution Approach 1:
The patent applies local quality by differentiating authentication requirements based on local environmental characteristics (space reliability). Instead of applying uniform authentication across all contexts, the system tailors authentication strength to match the specific trustworthiness of each authentication-processing space. This localized approach maintains security where needed while improving overall authentication efficiency by reducing requirements in trusted environments.
Solution Approach 2:
The patent implements partial action by applying authentication measures proportionally rather than excessively. The system determines the minimum necessary authentication based on space reliability, avoiding unnecessary authentication steps in high-trust environments while maintaining adequate security in low-trust environments. This proportional approach optimizes productivity by eliminating redundant authentication actions.
3Ease of operation
If space reliability determination is implemented to reduce authentication steps, then convenience is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the authentication system into distinct modules: space identification module, space reliability determination module, and authentication scheme selection module. This segmentation allows each component to perform its specific function independently, making the overall complex system manageable and maintainable while enabling convenient adaptive authentication.
Solution Approach 2:
The patent implements preliminary action by pre-establishing multiple authentication schemes (first, second, third schemes) with varying security levels. The system prepares these authentication options in advance and simply selects the appropriate one based on space reliability determination. This preliminary preparation reduces runtime complexity while enabling convenient adaptive authentication.
