Secondary-Device Authentication for Locked User Device Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a secure and reliable method to recover a user device when primary authentication fails, preventing permanent unavailability due to multiple failed authentication attempts.
Innovation Solution
A system that provides alternative user authentication methods using a secondary device, such as a smartphone, through wireless connection or scannable codes, to unlock the primary device and execute intended actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system locks the first user device after detecting a threshold number of failed authentication attempts, then security is improved, but user accessibility deteriorates
Solution Approach 1:
The patent introduces a second user device as an intermediary to mediate the authentication process. When the first device is locked after failed authentication attempts, the second device serves as a mediator to verify the user's identity through alternative authentication methods (such as receiving push notifications, scanning QR codes, or entering verification codes). This intermediary approach maintains security by requiring verification while restoring accessibility by providing a different authentication path that bypasses the locked first device.
2Ease of operation
If the system provides multiple alternative authentication options, then user accessibility is improved, but system complexity increases
Solution Approach 1:
The patent implements multi-functionality by enabling the second user device to perform multiple authentication methods through a single integrated system. The second device can handle push notifications, QR code scanning, verification code entry, and other authentication mechanisms universally. This approach provides authentication flexibility across different scenarios while managing system complexity by consolidating these functions into a unified second device interface rather than requiring separate systems for each authentication method.
3Reliability
If the system requires a second user device for alternative authentication, then authentication reliability is improved, but device availability requirements worsen
Solution Approach 1:
The patent applies dynamics by making the authentication system adaptable to different scenarios based on device availability. The system dynamically adjusts its authentication requirements: when the first device is locked, it requires a second device; when the first device remains accessible, it uses standard authentication. The second device itself can dynamically support multiple authentication modes (push notifications, QR codes, verification codes) based on what is most appropriate for the current situation, thereby maintaining verification reliability while improving adaptability to various user contexts.

AI summary
A system is provided for user device recovery through alternative user authentication processes. In particular, the system may provide to the user one or more alternative user authentication methods in the event that a primary user authentication method associated with a first user device is unsuccessful, where the first user device may become unavailable as a result. In such a scenario, the one or more alternative user authentication methods may include an authentication process involving a second user device. The system may assess the capabilities of the second user device in authenticating the user, and subsequently initiate a secondary authentication process using the second user device. Based on successfully completing the secondary authentication process, the system may allow the user to recover the first user device in the event that the first user device is unavailable.
