Dynamic ID Tag Pairing for Unauthorized Object Removal Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems are inadequate in preventing the unauthorized removal of valuable items from specific areas due to limitations in technology, particularly in dynamic 'many-to-many' environments, where multiple entities are associated with multiple objects, and current solutions like RFID tags are not practical for widespread use.
Innovation Solution
A method and system using ID tags with a key ID tag and an object ID tag, where the key ID tag calculates a target ID based on a source ID and algorithm code, stored in a central database, and compared at entry and exit points to track and prevent unauthorized movement of objects, utilizing RFID or barcode technology for identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RFID tags are used for object tracking, then object identification capability is improved, but system complexity and cost increase due to logging requirements and tag management
Solution Approach 1:
The patent extracts the logging and tag management functions from the RFID system, keeping only the essential object identification capability through EPC tags. The complex logging infrastructure is removed, and objects are tracked through simple database lookups using calculated target IDs derived from EPC codes, eliminating the need for manual tag registration and oversight.
Solution Approach 2:
The patent uses disposable EPC RFID tags that can be freely attached and removed without management overhead. These tags are treated as temporary, inexpensive identifiers that don't require registration or tracking, contrasting with permanent, managed RFID tags that require logging infrastructure.
2Reliability
If guards or video cameras are used for security, then theft prevention capability is improved, but operational cost and resource requirements increase
Solution Approach 1:
The patent replaces mechanical security systems (guards and video cameras) with an automated electronic system using RFID tags, readers, and database lookups. This substitution eliminates the need for human resources and complex surveillance infrastructure while maintaining or improving theft prevention capability through automatic notification when unauthorized objects leave predefined areas.
3Measurement precision
If traditional RFID systems are used, then object tracking is improved, but adaptability to dynamic many-to-many environments deteriorates due to static one-to-many association
Solution Approach 1:
The patent implements dynamic associations between objects and locations through calculated target IDs that are generated on-the-fly based on EPC codes and location identifiers. This allows objects to be freely associated with multiple locations and entities without pre-registration, enabling flexible many-to-many relationships that adapt to changing environments.
Solution Approach 2:
The patent creates a universal tracking system where a single EPC tag can serve multiple entities and locations simultaneously. The calculated target ID mechanism allows the same tag to be associated with different owners, locations, and contexts dynamically, providing multi-functional adaptability that traditional static RFID systems cannot achieve.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This system effectively tracks and prevents unauthorized removal of objects by entering a notification state when an object ID tag is associated with an active calculated target ID, enhancing security and reducing theft in various settings, including retail and public spaces.

Data Source
AI summary
A system and method of loss prevention using a pair of ID tags is disclosed. The user or owner of the protected object can dynamically create a security perimeter by using key ID tag and object ID tag pair. An object ID tag is either embedded in or attached to a protected object. A key ID tag, which is in a handheld device, has protection to prevent unauthorized scan. The object ID tag information can only be obtained from key ID tag using preprogrammed algorithm. The area security system will be armed after reading and validating a key ID tag scanned by the user. If anyone takes protected object with object ID tag out of the area without proper key ID tag authentication, alarm will be triggered.
