Cross-Device Authentication for Secure Remote Screen Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for unlocking a device during multi-screen collaboration are inefficient and inconvenient, requiring direct user interaction on the locked device.
Innovation Solution
A method where a first electronic device receives operation information from a second electronic device, collects authentication information, and performs unlocking based on user authentication from the second device, ensuring security and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user performs unlocking operation directly on the locked device, then the unlocking security is maintained, but the user convenience and operation efficiency deteriorate
Solution Approach 1:
The patent introduces a second electronic device as an intermediary to perform the unlocking operation. The second device collects authentication information and sends unlocking commands to the first (locked) device, allowing the user to unlock remotely while maintaining security through the authentication protocol.
Solution Approach 2:
The unlocking process is segmented into separate functions: the second electronic device handles authentication information collection and user interaction, while the first device performs the actual unlocking execution. This segmentation allows convenient remote operation while preserving security.
2Productivity
If the unlocking operation is performed remotely on another device, then the user convenience is improved, but the system complexity increases
Solution Approach 1:
The second electronic device is given multi-functionality, serving both as a display/interaction device and as an authentication device. This universal approach enables remote unlocking without requiring additional specialized hardware, thus improving efficiency while limiting complexity growth.
3Reliability
If authentication information is collected through multiple protocols, then the authentication security is enhanced, but the device complexity increases
Solution Approach 1:
The system changes the parameter of authentication protocol to support multiple types (password, fingerprint, facial recognition). By making the authentication method a variable parameter rather than a fixed mechanism, the system achieves enhanced security through protocol diversity while managing complexity through flexible configuration.

AI summary
An electronic device unlocking method is applied to a first electronic device and includes receiving operation information sent by a second electronic device; sending first information to the second electronic device when determining, based on the operation information, to unlock a to-be-unlocked object of the first electronic device, where the first information is used by the second electronic device to collect authentication information required for unlocking the to-be-unlocked object; obtaining authentication information from the second electronic device to perform authentication of a user; and unlocking the to-be-unlocked object of the first electronic device when the authentication of the user succeeds.
