Multi-layer identifier label for product authenticity verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face challenges in verifying the authenticity and origin of products, as existing systems lack effective methods to ensure the accuracy of product information and traceability, leading to difficulties in identifying defective items for recalls.
Innovation Solution
A multi-layer identifier label system featuring a public and private identifier, where the private identifier is only accessible after a tamper-evident action, allowing consumers to verify product authenticity and track item history through a networked environment, facilitating item-level tracking and recall management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-layer identifier label is used, then the device complexity is reduced, but the security and authenticity verification capability deteriorates
Solution Approach 1:
The identifier label is divided into multiple layers: a first layer containing a first identifier and a second layer containing a second identifier. This segmentation allows the system to provide both public identification (first identifier) and secure verification (second identifier) without requiring a single complex structure, thereby improving authenticity verification while maintaining manageable complexity.
Solution Approach 2:
The label structure employs a nested configuration where the second layer with the private identifier is positioned beneath the first layer with the public identifier. This nesting allows the simpler first layer to be applied first, with the more secure second layer nested underneath, achieving enhanced security without requiring complete redesign of the entire label system.
2Reliability
If the private identifier is always visible, then the ease of operation is improved, but the security and tamper detection capability deteriorates
Solution Approach 1:
The first layer containing the public identifier is applied to the item first, allowing immediate identification and tracking. The second layer with the private identifier is then applied over it, creating a tamper-evident structure. This preliminary action sequence enables normal operations to proceed while maintaining security, as the private identifier is only exposed when tampering occurs.
Solution Approach 2:
The first layer acts as an intermediary between the public identifier system and the private identifier system. It allows public identification to function normally while protecting the private identifier beneath it. The intermediary layer can be removed or damaged to reveal the private identifier, providing tamper detection without preventing normal access to public information.
3Reliability
If comprehensive item tracking is implemented, then the recall effectiveness is improved, but the loss of time for data collection and processing deteriorates
Solution Approach 1:
Item history records are created and maintained in advance as items move through the supply chain, rather than being compiled during a recall event. The system continuously records events such as manufacturing, shipping, and storage with their corresponding timestamps and locations. This preliminary data collection eliminates the need for time-consuming data gathering during recalls, enabling immediate identification of affected items.
Solution Approach 2:
The system provides continuous feedback about item location and status through the tracking network. When a defect is identified, the feedback mechanism allows rapid query of the item history record to determine which items are affected and where they are located. This real-time feedback capability dramatically reduces recall time compared to manual tracking systems.

AI summary
Disclosed are various embodiments of multi-layer identifier labels. In one embodiment, a multi-layer identifier label includes an upper layer bearing a public identifier, a lower layer bearing a private identifier, and an adhesive backing below the lower layer. The upper layer may be removably attached to the lower layer, and the lower layer may be non-visible underneath the upper layer. Peeling away the upper layer to reveal the lower layer may be a tamper-evident action.
