IoT Parcel Tamper Seal with RFID and Solar Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parcel tracking systems lack real-time monitoring and digital security, leading to potential delivery delays and tampering issues, as they require users to manually retrieve updates and do not provide proactive notifications or real-time location tracking.
Innovation Solution
A parcel monitoring system featuring an electronic device with a keypad and display that uses a dynamically generated Delivery OTP for authentication, enabling real-time GPS tracking and tamper detection, along with a fail-safe mechanism for device malfunctions or power issues, ensuring secure and efficient delivery verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electronic security seals are used, then wireless tamper reporting is improved, but device cost increases and battery power consumption limits update frequency
Solution Approach 1:
The patent replaces battery-powered electronic security seals with a passive RFID-based system that uses electromagnetic fields for power and communication. The RFID tag contains no battery and requires no mechanical battery replacement, eliminating power consumption concerns while maintaining wireless tamper reporting capability through the RFID reader-writer device.
Solution Approach 2:
The system uses disposable or reusable RFID tags that can be easily replaced or reset. The tag itself is a low-cost component that can be programmed and reprogrammed multiple times, providing an economical alternative to expensive battery-powered e-seals while maintaining security functionality.
2Loss of information
If real-time GPS tracking is implemented, then delivery location monitoring is improved, but device power consumption increases
Solution Approach 1:
Instead of continuous real-time GPS tracking that would drain battery power, the system uses periodic location updates triggered by specific events such as package pickup, delivery attempts, or tamper detection. The RFID system activates GPS tracking only when needed, significantly reducing overall power consumption while still providing critical location information.
Solution Approach 2:
The system automatically activates tracking and notification functions when specific conditions are met, such as when the package is scanned at a delivery location or when tamper detection occurs. This event-driven approach eliminates the need for continuous power consumption while ensuring location information is captured when most relevant.
3Reliability
If dynamic OTP authentication is used, then delivery security is improved, but device complexity increases
Solution Approach 1:
The system introduces a centralized server as an intermediary that generates, stores, and verifies dynamic OTP codes. The RFID tag and reader device communicate simple authentication requests and responses, while the complex OTP generation and verification logic resides on the server, keeping the physical device complexity low while maintaining high security.

AI summary
The present disclosure relates to a parcel monitoring system, method and electronic device (e-device) for secure packaging, shipment, receipt and tracking of parcels. The tamper-proof seal (102) can include a transceiver (406) to communicate with one more devices at remote location to transmit information associated with the package, and a plurality of slots (408-1, 408-2, 408-3, 408-4) adapted to receive one or more strings (104) in each of said plurality of slots (408-1, 408-2, 408-3, 408-4). In an embodiment, the said one or more strings (104) are electrically connected to each of said plurality of slots such that an interruption in said electrical connection triggers said transceiver (406) to transmit a notification to said one more devices as an indication of seal tampering.
