Tamper-Evident Seal With Secure Element For Product Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for authenticating sealed products, such as labels and seals, are inadequate in preventing sophisticated counterfeiting, especially in products like medicines and alcoholic beverages where tampering can lead to serious harm and is difficult to detect.
Innovation Solution
A system and method using a secure element integrated with the product's seal, which includes a tamper detection module, data storage for a digital signature, and communication capabilities to authenticate the product's authenticity via a cryptographic key and certificate authority, altering the digital signature upon detection of tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional labels or seals are used for product authentication, then the authentication method is simple and easy to implement, but the system cannot protect against sophisticated counterfeiting and tampering detection capability is weak
Solution Approach 1:
The patent embeds a secure element (containing cryptographic keys and digital signature algorithms) within the product seal structure. This nested configuration integrates authentication functionality directly into the sealing mechanism, allowing the seal to simultaneously perform its primary function of closing the container and its secondary function of providing cryptographic authentication. The secure element is physically nested within the seal layers, creating a compact integrated system that enhances security without requiring separate authentication hardware.
Solution Approach 2:
The patent introduces a certificate authority (CA) as an intermediary that issues digital certificates to legitimate product seals. This intermediary enables trust establishment between the product manufacturer and consumers by providing a third-party verification mechanism. The CA-signed digital certificate serves as a mediator that proves the authenticity of the cryptographic keys embedded in the seal, allowing authentication without requiring direct verification of the physical seal integrity by the end user.
2Reliability
If the seal structure is made more secure to prevent tampering, then anti-counterfeiting capability improves, but the seal becomes more difficult to manufacture and integrate with the product
Solution Approach 1:
The patent divides the seal into distinct functional layers: an outer seal layer providing physical sealing, an embedded secure element containing cryptographic functionality, and integration features that connect the secure element to the seal structure. This segmentation allows each component to be manufactured and tested separately using appropriate processes, then assembled into the complete seal assembly. The secure element can be manufactured using standard semiconductor processes, while the seal itself is manufactured using conventional sealing materials and methods.
Solution Approach 2:
The patent designs the seal structure to perform multiple functions simultaneously: the secure element serves both as part of the sealing mechanism (maintaining physical integrity) and as an authentication device (providing cryptographic verification). The integration features of the secure element serve dual purposes of mechanical attachment and electrical connection for tamper detection. This multi-functionality reduces the total number of separate components needed, simplifying the overall manufacturing process while enhancing security capabilities.

AI summary
A system for detecting tampering in a product having a tamper-detector seal, including a secure element configured to store a digital signature and a data associated with the digital signature, transmit the digital signature and the data associated with the digital signature in response to a request, detect tampering of the tamper-detector seal, and modify the data associated with the digital signature if tampering is detected. The system further includes a seal validation device configured to receive a public key associated with the product, request the digital signature and the data associated with the digital signature from the secure element, and validate the digital signature utilizing the data associated with the digital signature and the public key associated with the product.
