Screen Mirroring via Peripheral Request and Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen mirroring technologies expose user personal information as they require the mobile device to initiate the mirroring function, making it difficult to protect sensitive data when the device is not physically present.
Innovation Solution
An electronic device equipped with a communication circuit, memory for authentication information, and a processor that broadcasts messages to peripheral devices, allowing them to request and authenticate screen mirroring, thereby enabling the device to initiate the function at the request of an external device and ensuring user privacy through authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile device initiates the screen mirroring function, then the screen data can be transmitted to peripheral devices, but user personal information is exposed and difficult to protect
Solution Approach 1:
The patent inverts the traditional screen mirroring initiation model. Instead of the mobile device (electronic device) actively initiating and transmitting screen data to peripheral devices, the system allows authenticated peripheral devices to request and receive screen data. This inversion fundamentally changes the data flow direction and control paradigm, enabling the electronic device to maintain information security while still providing screen mirroring functionality through an authentication-based request system
2Ease of operation
If the screen mirroring function is initiated only by the mobile device, then user control is maintained, but the function is only available when the user has the mobile device in person
Solution Approach 1:
The patent implements a self-service mechanism where authenticated peripheral devices can autonomously request screen data without requiring continuous user intervention. The electronic device maintains security through authentication while allowing authorized devices to independently initiate screen mirroring requests, enabling remote access functionality while preserving user control through the authentication framework
3Object-affected harmful factors
If authentication is implemented for screen mirroring, then user personal information is protected, but the screen mirroring function requires additional authentication steps
Solution Approach 1:
The patent implements preliminary authentication where the electronic device pre-authenticates peripheral devices before allowing them to request screen data. This upfront authentication establishes trusted relationships in advance, enabling subsequent screen mirroring operations to proceed without repeated authentication steps. The authentication burden is front-loaded, after which the system operates smoothly with pre-established trust
Data Source
AI summary
An electronic device is disclosed. An electronic device comprises a display, a communication circuit configured to communicate with a first peripheral device, a memory configured to store first authentication information associated with the first peripheral device, and a processor, wherein the processor is configured to control the electronic device to: broadcast a first message via the communication circuit, receive a connection request message from the first peripheral device receiving the first message, authenticate the first peripheral device based on the first authentication information associated with the first peripheral device in response to the reception of the connection request message, and transmit screen data being displayed on the display to the first peripheral device via the communication circuit based on the authentication being valid.
