Vertically Staggered Server Network for Dynamic RFID Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID data carrier systems form a static information system, limiting the ability to dynamically change the type and scope of information available to different groups of recipients, requiring multiple RFID tags and necessitating RFID data carrier exchange for access control adjustments.
Innovation Solution
A method utilizing a vertically staggered server network with a lower server acting as a mailbox for RFID data carriers, allowing controlled data transmission to upper servers, enabling dynamic access control and information scope adjustments by administrators, with NFC-enabled devices facilitating data transfer and authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple RFID data carriers are assigned to an object with independent data connections to different recipient groups, then information access can be restricted to specific groups, but the system becomes static and requires exchanging RFID carriers for changes
Solution Approach 1:
The system segments the information architecture by separating the static RFID data carrier from the dynamic server network. The RFID carrier contains only identification data, while the actual information is segmented across multiple server levels (lower server, upper servers) that can be independently accessed and modified by different authorized groups.
Solution Approach 2:
The server network acts as an intermediary between the RFID data carrier and the recipient groups. Instead of direct connections from multiple RFID carriers to multiple groups, the system uses lower servers and upper servers as mediators that manage data transmission and access control dynamically.
2Device complexity
If a single RFID data carrier is used for an object, then the system structure is simplified, but the ability to dynamically change information scope and recipients is limited
Solution Approach 1:
The system adds a vertical dimension to the information architecture by introducing server levels (lower server, upper servers) above the single RFID carrier. This vertical stacking allows multiple layers of access control and information filtering without complicating the RFID carrier structure itself.
Solution Approach 2:
The system creates virtual copies of the RFID data carrier's information across multiple server levels. The lower server stores a copy of the data, and upper servers store additional copies with different access permissions, allowing dynamic access control without modifying the physical RFID carrier.
3Productivity
If direct access from upper server to RFID data carrier is allowed, then data transmission is simplified, but security and controlled access are compromised
Solution Approach 1:
The lower server acts as a mandatory intermediary between upper servers and RFID data carriers. All data transmission must pass through the lower server, which verifies access permissions and controls the flow of information, maintaining security while enabling efficient transmission through automated access checks.
Solution Approach 2:
The lower server performs preliminary access verification and data preparation before transmitting information to upper servers. By checking access permissions in advance and preparing the data appropriately, the system ensures security is maintained while avoiding the need for complex real-time security checks during transmission.

AI summary
The invention relates to a method and an arrangement for transmitting an object data record, which is stored in a data memory area of a lower server, to an upper server, wherein the lower server and the upper server are arranged in a server complex comprising at least one upper server, and the servers are arranged on vertically staggered server levels, wherein the explicit association between the object data record and a particular object is made by means of addressing of the server data memory area by an access data record that is stored in an access data memory area of an RFID data storage medium connected to the object, the object data record being transmitted to the upper server by dint of access to the data memory area of the lower server.
