Optical Shield Wallpaper Tamper Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for preventing tampering and counterfeiting in shipping containers, such as RFID tags, are inadequate as they can be hacked, costly, or impractical for small items, and existing electromagnetic and light-based authentication methods are unreliable due to environmental noise and operator interpretation issues.
Innovation Solution
The implementation of Optical Shield Wallpaper, which embeds optical fibers in flexible media covering all interior container surfaces, using specialized manufacturing techniques and digital signal processing to generate a unique Optical Signature for authentication, and the iLockBox for real-time monitoring and notification of breaches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID tags are used to authenticate products in shipping containers, then product authenticity can be verified, but the tags can be hacked, removed, or transferred to counterfeit items
Solution Approach 1:
The patent combines optical fibers with the container structure itself, embedding them in the walls and surfaces. This merging of the authentication medium with the container creates a unified system where the container's physical integrity is directly linked to its authentication capability, making it impossible to separate the tag from the container or transfer it to another item.
Solution Approach 2:
The optical fiber network is divided into multiple segments distributed throughout the container walls and surfaces. Each segment independently contributes to the overall authentication signature, so that any breach or tampering with a specific segment is detectable as a change in the authentication code, providing granular security monitoring.
2Reliability
If RFID tags are placed on each individual product item, then comprehensive authentication is achieved, but the cost increases significantly and small items cannot accommodate tags
Solution Approach 1:
The optical fiber authentication system serves multiple functions simultaneously: it authenticates the container itself, monitors structural integrity, detects breaches, and verifies the presence of contents. This multi-functionality eliminates the need for separate authentication tags on each item, as the container's optical fiber network provides comprehensive security for all contents collectively.
Solution Approach 2:
Instead of placing physical authentication tags on each small item, the patent uses the optical fiber network to create a digital/authentication copy of the container's security state. The authentication is performed at the container level rather than the individual item level, providing equivalent security coverage without the physical constraints of tagging tiny components.
3Ease of operation
If electromagnetic signals are used for authentication, then remote reading is possible, but environmental noise and operator interpretation reduce reliability
Solution Approach 1:
The patent replaces electromagnetic signal-based authentication with optical fiber-based authentication. Optical fibers transmit light signals that are immune to electromagnetic interference and environmental noise. The authentication process uses light transmission characteristics through the fiber network, providing stable and reliable readings that are not affected by external electromagnetic conditions or operator interpretation.

AI summary
The disclosed embodiments provide a method for tamper-proof protection of containers used for shipment of goods. An optical fiber is embedded in an Optical Shield Wallpaper which lines all interior surfaces of any size of a shipping container, package, box, barrel or other shaped container. Wallpaper is manufactured using large scale rollers that press fibers with encapsulated adhesives onto an appropriate medium. Small medicine containers are protected with a fiber optic shield and sensors manufactured using ink jet printing techniques. Light is applied to the optical fiber and a measurement of optical fiber characteristics is performed. Digital signal processing is used to generate pedigree information, which may include items such as shipping location, serial numbers and lot numbers for the goods. The status of the autonomous anti-tampering system is monitored real-time for unauthorized intrusions. Intrusions detected are relayed to an authorized recipient via a variety of communication channels.
