Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current NFC middleware fails to effectively bind NFC applications with mobile operators, leading to unauthorized access and misuse of NFC devices, as it lacks a mechanism to ensure only operator-related permissions are used.

Innovation Solution

A method and device that utilize NFC middleware to analyze and process operation commands, verify service permissions based on SIM card information, and filter data to ensure only authorized operations are executed on NFC devices, thereby binding NFC applications with mobile operators.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If NFC middleware provides universal services for upper layer NFC applications, then adaptability is improved, but security control and operator binding capability deteriorate

Engineering Contradiction:

ImproveadaptabilityVSAvoidsecurity control

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The NFC middleware is segmented into multiple functional modules: a permission verification module that checks operator permissions, an NFC device management module, and an application interface module. This segmentation allows the system to maintain universal adaptability while implementing granular security control through dedicated permission verification components that operate independently for each NFC operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The NFC middleware acts as an intermediary layer between upper layer NFC applications and the NFC device hardware. It introduces a permission verification mechanism that mediates all NFC operations by checking operator permissions before allowing access to NFC functions, thus providing security control without affecting the adaptability of the application layer.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If NFC middleware shields differences between hardware and system software, then ease of operation is improved, but operator binding capability and security verification deteriorate

Engineering Contradiction:

Improveease of operationVSAvoidoperator binding capability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary permission verification through the NFC middleware before actual NFC operations occur. The middleware pre-establishes operator binding relationships and verifies permissions in advance, so that when applications access NFC devices, the security control is already in place without complicating the ease of operation for end users.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method, device and terminal for binding an NFC application and an operator are disclosed in the embodiments of the present invention. The method comprises: after receiving an operation command sent by an upper application program of a terminal, an NFC middleware judging whether the operation command is within an NFC service permission opened by the terminal at an operator; when determining that the operation command is within the NFC service permission opened by the terminal at the operator, sending the operation command to an NFC device; the NFC device reading original NFC data according to the information in the operation command; and after performing data processing on the original NFC data, sending the data to the upper application program.
