RFID Event Tracking System with Role-Based Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tracking and data management systems in supply chains lack standardized methods to ensure data access control, leading to issues with data loss, reliability, and handling of incomplete or industry-specific data, particularly in ensuring that sensitive information is only accessible to authorized entities.
Innovation Solution
The system allows users to select between event discovery mode and compensation mode for handling RFID events, enabling controlled access and data correlation, using a sensor edge server and product information management hub to ensure data integrity and security through virtual private databases and role-based visibility control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If RFID tags are used for automated bulk scanning and tracking, then productivity and data collection efficiency are improved, but data security and access control become more difficult to manage
Solution Approach 1:
The patent segments data access control into multiple levels: event data namespace, dimension data namespace, and role-based access control lists. This segmentation allows the system to manage complex RFID data from bulk scanning operations while providing granular security control to different users and systems based on their specific needs and authorization levels.
2Ease of operation
If data is stored in a standardized format for easy access, then ease of operation is improved, but data integrity and handling of industry-specific variations may be compromised
Solution Approach 1:
The patent introduces an intermediary layer consisting of dimension data tables and event data namespaces that mediate between standardized RFID event data and industry-specific requirements. This intermediary structure allows standardized data storage while enabling flexible interpretation and adaptation to different industry needs through configurable dimension data without compromising data integrity.
3Loss of information
If all RFID event data is made accessible to all entities in the supply chain, then visibility and transparency are improved, but data security and unauthorized access risks increase
Solution Approach 1:
The patent implements local quality by assigning different access control policies to different data namespaces and entities. Each supply chain entity receives customized access control lists that grant visibility only to the specific event data and dimension data relevant to their role, maintaining supply chain transparency while preventing unauthorized access to sensitive information through role-based security.

AI summary
An RFID event tracking and management system provides a standardized approach that can be utilized by various industry verticals. Loss of captured event data, such as RFID generated through an RFID event, can be prevented through a series of guarantee semantics. Approaches also allow an entity to control the integrity level of their data, such as where dimension data is not available to be correlated with coded event data. An entity can decide whether to allow querying on event data that has not been correlated with dimension data useful in interpreting the location data. The entity can alternatively decide to only allow access and querying of event data when the corresponding location and dimension data are compensated.
