Proactive Authentication Proof for Multi-Device Offline Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-device authentication systems face challenges with connectivity issues, such as network lags and disconnections, which prevent users from accessing protected resources when devices are offline or disconnected from the network.
Innovation Solution
A proactive user authentication method that generates a proof of authentication on one device, allowing subsequent access to protected resources even when the first device is disconnected from the network, by validating cryptographic information received from a second device against the stored proof of authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time network authentication is implemented, then security is improved, but connectivity issues cause access failures
Solution Approach 1:
The system performs authentication in advance and stores the authentication result locally on the user device. When the user needs to access a protected resource, the previously obtained authentication result is used directly without requiring real-time network connection, thus resolving the contradiction between security and connectivity reliability.
2Reliability
If multi-device authentication protocol is used, then security is improved, but network lag causes delays
Solution Approach 1:
The authentication process is completed beforehand and the authentication result is cached locally. When accessing protected resources on different devices, the system retrieves and validates the pre-stored authentication result instead of performing the full authentication protocol again, thereby eliminating network lag and reducing authentication wait time while maintaining security.
3Measurement precision
If online authentication is required, then authentication accuracy is improved, but offline access is prevented
Solution Approach 1:
The system performs accurate authentication when the device is online and stores the authentication result locally. This allows the device to access protected resources offline using the pre-validated authentication result, thus maintaining both authentication accuracy and offline access capability.
Solution Approach 2:
The authentication result obtained online is copied and stored locally on the device. This local copy enables offline authentication without compromising the accuracy of the original online authentication process, allowing the system to adapt to both online and offline environments.

AI summary
Methods, apparatus, and processor-readable storage media for proactive user authentication for facilitating subsequent resource access across multiple devices are provided herein. An example computer-implemented method includes validating an authentication result received via a first user device; generating, in response to validating the authentication result, a proof of authentication that relates to the authentication performed via the first user device; outputting the proof of authentication to the first user device; receiving, via a second user device in connection with a request to access a protected resource, cryptographic information comprising at least a portion of the proof of authentication output to the first user device; validating the cryptographic information received via the second user device against the proof of authentication; and granting, to the second user device, access to the protected resource in response to validating the cryptographic information against the proof of authentication.
