Task Handoff Fingerprint Verification for Multi-Device Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing task handoff methods in multi-device interactions lack adequate security measures, leading to potential privacy disclosure and data loss when users switch tasks between devices, as content synchronization can be triggered unintentionally or accessed by unauthorized users.
Innovation Solution
A method that involves displaying prompt information on a second device to initiate task handoff, collecting and matching user fingerprints to ensure authorized execution, using fingerprint recognition systems to verify user identity, and executing tasks only when the fingerprint information matches registered data, thereby preventing unauthorized access and data loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content synchronization is enabled between multiple devices using handoff function, then task continuity and user experience are improved, but privacy disclosure and data security deteriorate when unauthorized users access the devices
Solution Approach 1:
The system performs preliminary fingerprint registration and stores fingerprint templates in advance before task handoff occurs. When a user attempts to handoff a task, the system immediately verifies the fingerprint against the pre-stored template, preventing unauthorized access before privacy disclosure can occur.
Solution Approach 2:
The fingerprint verification system acts as an intermediary between the task handoff function and content synchronization. It mediates by verifying user identity through fingerprint matching before allowing the handoff to proceed, thus protecting privacy while enabling legitimate task continuity.
2Productivity
If automatic task handoff is enabled between devices, then productivity and task efficiency are improved, but data loss risk increases when unauthorized users modify or delete content
Solution Approach 1:
Fingerprint templates are registered and stored in advance, creating a security barrier before task handoff. This preliminary authentication ensures that only authorized users can initiate or modify tasks during handoff, preventing unauthorized data loss while maintaining productivity.
Solution Approach 2:
The system provides immediate feedback through fingerprint verification results. When a user attempts task handoff, the system verifies the fingerprint and either permits or blocks the operation accordingly, providing real-time security feedback that prevents unauthorized modifications while allowing legitimate productivity-enhancing handoffs.
3Object-affected harmful factors
If fingerprint verification is added to the task handoff process, then data security and privacy protection are improved, but device complexity and operation steps increase
Solution Approach 1:
The fingerprint verification system is integrated into the existing task handoff interface, allowing users to verify their identity through the device's built-in fingerprint sensor without needing external verification tools or complex additional steps. The system serves itself by utilizing already-available biometric capabilities.
Solution Approach 2:
The fingerprint sensor serves multiple functions: it authenticates users for task handoff, verifies identity for content access, and can prevent unauthorized modifications. This multi-functionality reduces the need for separate verification systems, thereby minimizing added complexity while maximizing privacy protection.
Data Source
AI summary
A method includes: displaying, by a second device, prompt information, where the prompt information is used to inform a user that a task executed on a first device may be handed off to the second device for execution; receiving, by the second device, a first operation of the user, and collecting a fingerprint used when the user performs the first operation, where the first operation is used to request execution of the task on the second device; acquiring, by the second device, first fingerprint information and second fingerprint information by using the first device; calculating, by the second device according to the fingerprint used when the user performs the first operation and the first fingerprint information, third fingerprint information; and executing, by the second device, the task when the third fingerprint information matches the second fingerprint information.
