Application Handoff Verification for Trusted Cross-Device Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a multi-device scenario, application handoff can result in content being transferred to an application with an unreliable trust source, compromising user information security.
Innovation Solution
An application handoff method involving validity authentication and matching relationship verification is performed on a second terminal device before content transfer, ensuring only trusted applications receive the content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If application handoff is enabled without verification, then application handoff functionality is improved, but security is worsened due to potential transfer to untrusted applications
Solution Approach 1:
The patent performs validity authentication and matching relationship verification on the target application before allowing content handoff. This preliminary verification ensures that only authenticated and matched applications can receive handoff content, preventing security breaches while maintaining handoff functionality.
Solution Approach 2:
The patent introduces an intermediary verification mechanism that acts as a mediator between the source application and target application. The system validates the target application's identity and checks matching relationships before enabling direct content transfer, thus ensuring security without blocking legitimate handoff operations.
2Reliability
If validity authentication and matching relationship verification are performed, then security is improved, but system complexity is worsened
Solution Approach 1:
The patent implements self-service mechanisms where applications automatically perform validity authentication and matching verification without requiring manual user intervention. The system autonomously checks credentials and relationships, reducing the perceived complexity for users while maintaining robust security protocols.
Solution Approach 2:
The patent creates a universal authentication and verification framework that can handle multiple types of applications and handoff scenarios through a single integrated system. This multi-functional approach consolidates various security checks into one unified mechanism, reducing overall system complexity while maintaining comprehensive security coverage.

AI summary
Embodiments of this application provide an application handoff method and a terminal device, to avoid handing off content in an application to an application with an unreliable trust source, and improve application handoff security, so as to improve user experience. The method includes: A second terminal device receives a broadcast handoff notification from a first terminal device, where the broadcast handoff notification is used to request to hand off a first handoff application on the first terminal device to the second terminal device; the second terminal device determines a second handoff application based on the broadcast handoff notification, and performs validity authentication and matching relationship verification on the second handoff application, to obtain a validity authentication result and a matching relationship verification result; and the second terminal device displays a handoff contact point of the second handoff application when the validity authentication result is that the validity authentication succeeds, and the matching relationship verification result is that the matching relationship verification succeeds.
