Wireless Device Pairing via Restricted Input Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional authentication techniques require a wired peripheral device for user authentication, which is inefficient for users and costly for manufacturers, especially when wireless peripheral devices are intended to be the primary input source.
Innovation Solution
A computing device is configured to restrict inputs from a wireless device for uses other than authentication unless the user is authenticated, allowing the wireless device to pair with the computing device only after successful authentication, thus enabling its full functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional authentication techniques are used, then user authentication security is maintained, but wireless peripheral devices cannot function as primary input sources and additional wired devices are required
Solution Approach 1:
The authentication system is segmented into distinct phases: initial authentication phase where only authentication inputs are accepted from the wireless device, and post-authentication phase where full functionality is enabled. This segmentation allows the wireless device to gradually gain functionality while maintaining security during the authentication process.
Solution Approach 2:
The system performs preliminary authentication actions before enabling full device functionality. The wireless device is first restricted to authentication-only mode, and only after successful authentication does the system transition the device to full functionality mode. This preliminary action ensures security is established before versatility is granted.
2Reliability
If a wired peripheral device is provided for authentication, then authentication security is ensured, but user efficiency decreases and manufacturer costs increase
Solution Approach 1:
The wireless peripheral device is designed to serve multiple functions: it acts as both the authentication input device and the primary operational device. After authentication, the same wireless device that was used for authentication continues to function as the primary input device for all computing operations, eliminating the need for separate wired authentication devices and improving user efficiency.
3Reliability
If wireless peripheral devices are restricted to authentication uses only, then security is maintained, but device versatility is reduced
Solution Approach 1:
The device functionality is made dynamic rather than static. The wireless peripheral device transitions from a restricted authentication-only mode to a full-functionality mode based on the authentication state. This dynamic adjustment of device capabilities allows the system to maintain security during authentication while enabling full versatility after authentication succeeds.
Data Source
AI summary
In one or more implementations, a computing device receives an indication that a device is attempting to pair with the computing device. If a user is not currently authenticated with respect to the computing device, inputs received by the device are restricted from being used by the computing device for uses other than authenticating the user.
