Blockchain Device Management for Multi-Client Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In facial recognition payment scenarios, multiple characteristic acquisition devices are required for different payment clients on a terminal, leading to inconvenient payments for merchants and users.
Innovation Solution
A device management method based on a blockchain network is implemented, where a single characteristic acquisition device is used to support multiple clients by authenticating the device through a blockchain network, establishing an association relationship between the device and the clients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple characteristic acquisition devices are installed for different payment clients, then each client can independently perform facial recognition payments, but the device configuration complexity increases and convenience decreases
Solution Approach 1:
The patent implements a shared characteristic acquisition device that can be accessed by multiple payment clients through a device management platform. The device performs multiple functions by serving different clients sequentially, eliminating the need for separate devices for each client while maintaining payment reliability through blockchain-based authentication and device information verification.
2Reliability
If multiple characteristic acquisition devices are installed for different payment clients, then each client has dedicated device access, but user convenience deteriorates
Solution Approach 1:
The patent introduces a device management platform as an intermediary between the characteristic acquisition device and multiple payment clients. This platform handles device authentication, information verification, and client-device association through blockchain technology, ensuring authentication security while providing a unified, convenient interface for users across different clients.
3Device complexity
If a single characteristic acquisition device supports multiple clients, then device configuration complexity is reduced, but device authentication and security verification become more challenging
Solution Approach 1:
The patent implements a feedback mechanism where the device management platform continuously verifies device information against blockchain-stored data. When a client requests to use the characteristic acquisition device, the platform authenticates the device, checks its information integrity through blockchain verification, and establishes appropriate associations. This automated feedback loop simplifies the sharing model while maintaining rigorous security verification.

AI summary
In a method, device information of a characteristic acquisition device associated with a target terminal is acquired in response to a triggering operation for establishing an association relationship between the characteristic acquisition device and a target client in the target terminal. The device information is transmitted to the blockchain network such that each of node devices in the blockchain network authenticates the characteristic acquisition device according to the device information. A respective reference authentication result generated by each of the node devices is acquired. The respective reference authentication result indicates whether the characteristic acquisition device passes authentication of the respective node device. The association relationship between the target client and the characteristic acquisition device is established in response to the characteristic acquisition device passing the authentication according to the reference authentication results.
