NFC-Based DOI Scanning for Secure Service Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in distinguishing between multiple QR codes for different services on smartphones, leading to confusion and increased operational complexity when using QR code-based services.
Innovation Solution
Implementing a method and device that utilize near-field communication (NFC) to broadcast and scan digital object identifiers (DOIs) for identity verification and service information, allowing for adaptive selection of the appropriate QR code based on the service type and ensuring secure connections through identity verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple QR codes are provided for different services, then service functionality is improved, but user confusion and operational complexity increase
Solution Approach 1:
The system enables automatic service selection where the terminal device autonomously determines which QR code to use based on the service type it detects through NFC broadcasting. The device automatically matches the service type with the corresponding QR code without requiring user intervention or manual selection, thus resolving the contradiction between providing multiple services and avoiding user confusion
Solution Approach 2:
The system implements a feedback mechanism where the terminal device broadcasts NFC signals containing service type information, receives this information, and automatically adjusts its QR code selection accordingly. This closed-loop feedback system ensures the correct QR code is presented for the detected service, eliminating user confusion while maintaining multi-service capability
2Reliability
If identity verification is implemented during connection establishment, then security is improved, but connection establishment time increases
Solution Approach 1:
Identity verification is performed as a preliminary action during the connection establishment phase before actual service execution. The terminal device verifies the identity information embedded in the QR code against its own identity through NFC communication, ensuring security is established upfront. This preliminary verification prevents fraudulent connections while the streamlined process minimizes time loss
Solution Approach 2:
The system merges the identity verification process with the connection establishment process itself, rather than treating them as separate sequential steps. The NFC-based verification is integrated into the connection handshake, allowing security checks to occur concurrently with connection setup, thus improving security without proportionally increasing connection establishment time

AI summary
A method: broadcasting a first message comprising an apparatus type through near field communication; scanning a digital object identifier (DOI) that is displayed by a mobile terminal according to the first message and that matches the apparatus type, to obtain service information and identity information of the mobile terminal included in the DOI; broadcasting a second message generated based on the identity information; obtaining, from the mobile terminal, a request for a near field communication connection, the request being generated by the mobile terminal after the mobile terminal determines the second message includes information consistent with the identity information of the mobile terminal; verifying the request based on the identity information of the mobile terminal; in response to that the verification succeeds, establishing the near field communication connection to the mobile terminal; and executing a service through the near field communication connection according to the service information.
