RFID Asset Security System with Owner Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In open environments, such as office spaces, the theft of portable and valuable assets like personal computers and cell phones is challenging due to their small size and the ineffectiveness of existing security measures, leading to data loss and replacement costs for companies.
Innovation Solution
Implementing a method that uses RFID tags correlated with owner RFID tags at access points to trigger alarms if an asset's RFID is detected without the corresponding owner's tag, employing encryption through Identify Friend or Foe challenge response technology and optional magnetometers to prevent theft and ensure proper asset ownership verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable locks are used to secure personal computers, then asset protection is improved, but the cables can be cut making the security ineffective
Solution Approach 1:
The patent replaces mechanical cable locks with an electromagnetic RFID-based security system. RFID tags on assets communicate with readers at access points to verify ownership automatically, eliminating the need for physical cable locks that can be cut. This substitution of mechanical security with electromagnetic field-based verification resolves the contradiction by providing protection that cannot be physically compromised.
Solution Approach 2:
The patent introduces RFID tags as intermediaries between assets and security verification. Instead of direct physical restraint through cable locks, the system uses RFID technology as a mediator to establish and verify ownership relationships automatically at access points, making the security mechanism immune to physical tampering.
2Reliability
If manual security checks are performed at access points, then asset theft prevention is improved, but security personnel time and operational complexity increase
Solution Approach 1:
The patent implements self-service security verification where RFID tags on assets automatically communicate with readers at access points. The system independently verifies ownership and triggers alarms if unauthorized attempts are detected, eliminating the need for manual security checks and freeing security personnel from routine monitoring tasks.
Solution Approach 2:
The patent replaces manual security verification processes with automated RFID-based electronic verification. Access points equipped with RFID readers automatically detect tags, verify ownership against authorized lists, and control access without human intervention, thereby maintaining high security while significantly reducing personnel time requirements.
3Reliability
If RFID tags are correlated with owner tags at access points, then security breach detection is improved, but system complexity and false alarm potential increase
Solution Approach 1:
The patent implements a feedback-based security system where RFID readers continuously monitor for tag correlations between assets and authorized owners. When a mismatch is detected (asset tag present without corresponding owner tag), the system provides immediate feedback through alarm activation. This automated feedback loop enhances breach detection while keeping the verification logic simple and rule-based.
Solution Approach 2:
The patent applies local quality verification by checking for specific tag correlations at each access point location. Rather than complex centralized processing, each access point independently verifies the presence of paired owner and asset tags in its local environment, simplifying the overall system architecture while maintaining effective security monitoring.
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 method reduces security breaches by enabling automated and secure tracking of assets, reducing the need for manual checks and minimizing false alarms, thus enhancing security in open environments like offices, libraries, and rental car companies.
Implementation Method 1
Radio Frequency Identification (RFID) is a method of storing and remotely retrieving data using RFID tags or transponders. With RFID the electromagnetic coupling in the RF portion of the RF spectrum is used to transmit signals.
Data Source
AI summary
A method and apparatus for asset management in an open environment are disclosed. In one embodiment, the method correlates a person's RFID tag with an RFID of an asset and uses this information to determine whether an asset is allowed to pass an access point.
