NFC Tag Service Control via User Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Near-field communication (NFC) technologies face challenges in dynamically configuring services and enhancing security within specific use environments, particularly due to limitations in service customization and user access control.
Innovation Solution
An image-forming apparatus is equipped with an NFC tag to write and update information about NFC services, determining allowed services based on user login and employing an NFC module to manage service provision, ensuring appropriate service exposure and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If NFC services are made universally accessible, then ease of operation is improved, but security is worsened due to unauthorized access risks
Solution Approach 1:
The system performs preliminary authentication of user identity and authorization verification before allowing NFC service access. The server pre-establishes user credentials and service permissions, so that when NFC communication occurs, the service can be immediately granted or denied based on pre-verified authentication results, preventing unauthorized access while maintaining ease of operation for authorized users
Solution Approach 2:
The patent introduces a server as an intermediary between the NFC terminal and the service provider. The server acts as a mediator that receives authentication requests from terminals, verifies user credentials against stored data, and returns authorization decisions. This intermediary layer enables secure access control without complicating the user interface, as the server handles all security checks transparently in the background
2Adaptability or versatility
If NFC service configuration is made dynamic and customized, then adaptability is improved, but device complexity is worsened
Solution Approach 1:
The patent moves service configuration management from the device level to the server level, adding a new dimensional layer to the system architecture. Instead of each NFC device maintaining its own complex configuration data and authentication credentials, the server stores and manages all service configuration information centrally. This dimensional shift allows dynamic customization of NFC services without increasing individual device complexity, as the server handles all configuration management remotely
Data Source
AI summary
An apparatus includes an NFC tag to which information about at least one near-field communication (NFC) service, from among NFC services that are provided based on NFC, is written; a user interface to receive an input of log-in information from a user; a control unit to determine an NFC service that is allowed for the user in response to log in of the user; and an NFC module to update information that is written to the NFC tag according to a result of the determining.
