RFID Server Architecture for Data Storage Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RFID systems face limitations in data storage capacity, data management, and compatibility issues, making it difficult to store and manage object data, especially in public domains, and pose security risks due to sensitive data being stored on the transponder itself.
Innovation Solution
A method and system where object data is stored on server means, with RFID transponders used for identification, allowing for flexible and general identification across domains by using identification codes and task data to execute tasks on the server, reducing the need for complex reading devices and enhancing security by separating data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If object data are stored on the RFID transponder, then identification data are available, but data storage capacity is limited and security risks increase
Solution Approach 1:
The system segments data storage between two locations: identification data (such as object ID, serial number) are stored on the RFID transponder with limited capacity, while detailed object data (such as owner information, administrative data, multimedia) are stored separately on server means with unlimited capacity. This segmentation resolves the contradiction by allowing the transponder to store only essential identification data while the server stores the bulk of object data.
Solution Approach 2:
The system introduces server means as an intermediary between the RFID transponder and the reading device. The server acts as a mediator that receives identification data from the transponder via the reading device, retrieves corresponding detailed object data from its storage, and returns it to the reading device. This intermediary approach allows the transponder to remain simple while enabling access to extensive object data.
2Loss of information
If object data are stored on the RFID transponder, then identification is possible, but data management and protection become difficult
Solution Approach 1:
The system extracts detailed object data management from the RFID transponder and places it on external server means. The transponder retains only minimal identification data, while the server handles storage, management, and protection of comprehensive object data including owner information, administrative data, and multimedia content. This extraction resolves the contradiction by removing the burden of complex data management from the transponder.
Solution Approach 2:
The server means serves as an intermediary that centralizes data management functions. It handles data storage, retrieval, security protocols, and access control for detailed object data. The reading device communicates with the server through standardized protocols, while the transponder remains simple. This intermediary architecture simplifies the overall system by concentrating management complexity in a dedicated server rather than distributing it across numerous transponders.
3Ease of operation
If a single central database is used to collect object data, then data accessibility is improved, but system flexibility and security are reduced
Solution Approach 1:
The system segments the data storage architecture into distributed server means rather than a single central database. Each server can store object data for specific objects or object types, allowing parallel access and reducing bottlenecks. The reading device can query multiple servers simultaneously, improving accessibility while maintaining flexibility through the distributed nature of the storage system.
Solution Approach 2:
The server means are designed with universal interfaces and standardized communication protocols that allow them to handle diverse object data types. The system can accommodate different data formats, storage capacities, and access requirements while maintaining a unified approach through the server intermediary. This multi-functionality resolves the contradiction by enabling both centralized accessibility and distributed flexibility.
4Adaptability or versatility
If complex reading devices are used to handle different identification carriers, then compatibility is improved, but device complexity and cost increase
Solution Approach 1:
The reading device is designed with a universal interface that communicates with all RFID transponders through standardized protocols. The complexity of handling different data formats and object types is shifted to the server means, which process the identification data and retrieve appropriate object data. This universal reading device approach resolves the contradiction by maintaining simplicity at the reading device while achieving broad compatibility through server-side processing.
Solution Approach 2:
The server means act as an intermediary that handles the complexity of data interpretation and format conversion. The reading device simply reads identification data from the transponder and sends it to the server, which then retrieves and formats the detailed object data for display. This intermediary approach allows the reading device to remain simple while maintaining compatibility with diverse identification carriers and data formats.

AI summary
The present invention relates to a method and a system for obtaining object data representative of an object, wherein the object is provided with at least one identification carrier on which identification data are stored, the method comprising of : - reading identification data from the identification carrier with a read unit; - determining from the identification data location data of a network location of server means which are connected to an electronic network and on which object data representative of the relevant object are stored; - sending the identification data on the basis of the location data via a communication connection over the electronic network between the read unit and the server means associated with the determined network location; - the server means determining task data from the identification data; - having the server means execute the associated task on the basis of the task data so as to generate and/or process object data representative of the identified object.
