Cross-Device Authentication Data Sharing for Faster Secure Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-device authentication systems rely solely on device connections for user authentication, leading to security issues and inefficient, time-consuming authentication processes, especially when devices have different capabilities and limitations.
Innovation Solution
A system that shares authentication data between devices, allowing the second device to dynamically select authentication readings based on those previously performed by the first device, considering factors like proximity, location, and elapsed time, to enhance security and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each device performs its own complete authentication process independently, then authentication security is maintained, but authentication time and energy consumption increase
Solution Approach 1:
The system performs authentication readings on the first device before the user switches to the second device. These preliminary authentication results are then transferred and utilized by the second device, eliminating the need to repeat all authentication readings and reducing overall authentication time while maintaining security
Solution Approach 2:
The patent merges the authentication processes across multiple devices by transferring authentication data between them. The authentication readings obtained on the first device are combined with the authentication process on the second device, creating a unified cross-device authentication system that reduces redundancy
2Reliability
If each device performs its own complete authentication process independently, then authentication reliability is maintained, but energy consumption increases
Solution Approach 1:
Authentication readings are performed in advance on the first device before the user switches devices. The second device leverages these pre-performed readings, avoiding the need to consume energy for repeating all authentication measurements, thus reducing overall energy consumption while maintaining security
Solution Approach 2:
The system recovers and reuses authentication data from the first device on the second device. Instead of discarding the authentication readings performed on the first device, the system transfers and utilizes them on the second device, eliminating redundant energy-consuming authentication operations
3Productivity
If authentication readings are transferred between devices, then authentication efficiency improves, but security risks may increase
Solution Approach 1:
The system dynamically selects which authentication readings to transfer based on the specific capabilities and requirements of each device. Not all readings are transferred universally; instead, the selection is adapted to the second device's sensors and authentication needs, maintaining security while improving efficiency
Solution Approach 2:
The patent applies different authentication strategies to different devices based on their local characteristics. Each device's authentication process is tailored to its specific sensors and capabilities, with readings selected and transferred according to the receiving device's local requirements rather than using a uniform approach
4Reliability
If the second device performs all authentication readings independently, then authentication security is maintained, but the process becomes redundant and inefficient
Solution Approach 1:
The authentication processes of the first and second devices are merged into a unified system. Authentication readings obtained on the first device are combined with the second device's authentication process, eliminating redundancy and improving efficiency while maintaining the security requirements of both devices

AI summary
The authentication of a user across multiple devices includes the generation of authentication related data during an authentication process of a first device. The authentication process relating to a user's use of a second device is conducted in dependence on the authentication data generated during the authentication process of the first device. The authentication data may include the authentication readings that have been authenticated by the first device, a trust in the user, a location of the user, a proximity of the user to the device in use and a network device, and a time elapsed since the authentication process occurred on the first device. Beneficially, basing the authentication of a second device on the authentication process of a first device allows a trust in the user to be transferred.
