RFID Transponder Data Separation for Secure Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID systems face limitations in storing and managing object data due to limited storage capacity, difficulty in adapting data during the object's lifecycle, and lack of flexibility in data access and management, especially in public domains, where sensitive data can be compromised and third-party access is restricted.
Innovation Solution
A method and system where each RFID transponder is linked to an identification code stored on a server, allowing object data to be accessed and managed centrally, with command data executed on the server to generate or process object data, enabling secure and flexible access to object information across networks, even by third parties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If object data is stored on the transponder, then identification capability is improved, but storage capacity is exceeded and data security is compromised
Solution Approach 1:
The patent extracts object data from the transponder and stores it externally on server units accessible via network. The transponder only retains identification data and location data, while detailed object information is retrieved from external sources when needed, thus solving the storage capacity limitation.
Solution Approach 2:
The patent introduces server units as intermediaries between the transponder and the object data. These servers store and manage object data, acting as a mediator that provides data to reading units without requiring the transponder to store the data itself, thereby addressing both storage and security concerns.
2Ease of operation
If object data is stored on the transponder, then data accessibility is improved, but data security is worsened due to easy retrieval by unauthorized parties
Solution Approach 1:
By extracting object data from the transponder and storing it on external servers, the system maintains easy data access through network retrieval while preventing unauthorized access to the transponder's core identification data. The separation ensures that sensitive information remains protected on secure servers rather than being easily extractable from the transponder.
Solution Approach 2:
Server units act as secure intermediaries that control access to object data. They can authenticate reading units and selectively provide data, thus maintaining ease of operation for authorized users while implementing security controls to prevent unauthorized access, something that cannot be effectively achieved if data is stored directly on the transponder.
3Ease of manufacture
If a centralized database is used to store object data, then data management is improved, but system flexibility and usability are restricted
Solution Approach 1:
The patent segments the data management system into multiple independent server units distributed across the network, rather than using a single centralized database. Each server can independently store and manage object data, allowing the system to scale flexibly and adapt to different requirements while maintaining centralized management capabilities through the network architecture.
Solution Approach 2:
The server units are designed to be multi-functional, capable of storing different types of object data, serving multiple reading units, and adapting to various application scenarios. This universal design provides both centralized management benefits and system flexibility, as servers can be dynamically assigned and configured for different purposes.
4Adaptability or versatility
If complex readers are used to read various identification carriers in the public domain, then read-out capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the complexity of data interpretation and object data retrieval from the reading unit and relocates it to server units. The reader only needs to perform basic transponder reading and network communication, while the complex tasks of data validation, object data retrieval, and interpretation are handled by the servers, thus significantly reducing reader complexity.
Solution Approach 2:
Server units act as intermediaries that handle the complexity of interfacing with various identification carriers and data formats. The readers communicate with servers using standardized protocols, while the servers manage the complexity of different transponder types, data formats, and access protocols, thus simplifying the reader design without compromising read-out capability.
