NFC Authentication Server for IC Tag Content Rights Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing near field communication systems lack a flexible and efficient method to impose use restrictions on digital content, particularly when using IC tags, leading to potential unlimited use and copyright concerns.
Innovation Solution
An information processing method and device that acquire tag-unique and device-unique information through near field communication, transmitting these to a server for authentication and verification, allowing for flexible use restrictions on digital content by managing access and usage rights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital content is provided through near field communication using IC tags, then content delivery convenience is improved, but use restriction control becomes insufficient leading to potential unlimited use
Solution Approach 1:
The patent introduces a server as an intermediary between the near field communication system and digital content delivery. The server receives tag-unique information and device-unique information, performs authentication and verification, and then controls content delivery based on use restriction rules. This intermediary mechanism enables both convenient NFC-based access and reliable use restriction enforcement by decoupling the simple trigger (NFC) from the complex control logic (server-side authentication and restriction management).
2Reliability
If use restriction is imposed on digital content, then copyright protection is improved, but system complexity increases due to additional authentication processes
Solution Approach 1:
The patent segments the authentication and content delivery system into distinct functional components: (1) near field communication unit for acquiring tag-unique information, (2) device-unique information acquisition unit, (3) transmission unit for sending information to server, (4) reception unit for receiving authentication results and verification results, and (5) process execution unit for controlling content delivery. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability and copyright protection.
Solution Approach 2:
The server acts as an intermediary that centralizes the complex authentication and verification logic, reducing the complexity burden on the client device. The server handles tag-unique information verification, device-unique information verification, use restriction rule checking, and content delivery control, allowing the client device to maintain a relatively simple structure while still providing robust copyright protection.
3Reliability
If authentication and verification processes are implemented, then use restriction control is improved, but processing time increases
Solution Approach 1:
The patent implements preliminary action by pre-registering tag-unique information and device-unique information in the server before actual content delivery occurs. The server stores use restriction rules in advance and prepares authentication frameworks beforehand. When near field communication triggers content delivery, the server can quickly verify against pre-stored information and rules, significantly reducing real-time processing time while maintaining reliable use restriction control.

AI summary
There is provided an information processing method of an information processing device, including acquiring tag-unique information unique to an IC tag from the IC tag through near field communication, acquiring device-unique information unique to the information processing device, transmitting the acquired tag-unique information and the acquired device-unique information to an outside, and receiving, from the outside, an authentication result of the acquired tag-unique information and a verification result of right information for using the IC tag, which are obtained based on the transmitted tag-unique information and device-unique information.
