Product Authentication via Analog-Digital Pattern Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-counterfeit measures, such as tamper-resistant seals and holograms, are inadequate in preventing sophisticated counterfeiting of prescription and over-the-counter drugs, as they can be replicated by advanced counterfeiters, posing health risks and economic losses.
Innovation Solution
A system combining analog and digital identifiers, where an analog identification indicia with a random pattern is paired with a digital identification record encoded in a 2D barcode, allowing for authentication by comparing the item identifiers generated from both components, with visible analog signature taggents to enhance human detection and simplify the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sophisticated anti-counterfeit measures such as holograms and UV fluorescent micro-fibers are used, then product authentication reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The authentication system is divided into two independent components: an analog identification indicia (visual pattern) and a digital identification record (data storage). This segmentation allows each component to be optimized independently - the analog part for human verification and the digital part for machine reading, reducing overall system complexity while maintaining high reliability
Solution Approach 2:
A random pattern of identification features serves as an intermediary between the analog and digital components. This random pattern is visually detectable by humans and can be digitally captured and stored, bridging the gap between human verification and machine authentication without requiring complex specialized hardware
2Measurement precision
If UV illumination and specialized scanning hardware are required for authentication, then measurement precision is improved, but ease of operation and accessibility deteriorate
Solution Approach 1:
The analog identification indicia is designed to be self-verifying through visual inspection of the random pattern. Consumers can independently verify product authenticity using only their eyes and simple lighting conditions, without requiring specialized UV lights or complex scanning devices, thereby improving ease of operation while maintaining adequate detection precision
3Reliability
If advanced anti-counterfeit technologies are implemented, then reliability against sophisticated counterfeiting is improved, but manufacturing precision and process complexity increase
Solution Approach 1:
The system uses a digital identification record that is a digital copy or representation of the analog identification indicia. This allows the authentication information to be reproduced accurately through standard digital printing and data storage processes, avoiding the need for complex manufacturing processes required by physical holograms or embedded fluorescent fibers
Data Source
AI summary
A method of identifying or authenticating a product by providing an analog identification indicia including a randomized pattern of identification features on a first part of the product wherein one or more attributes of the randomized pattern of identification features correspond to an item identifier. A digital identification record is provided on a second part of the product including an encoded digital version of the item identifier. The product is viewed from two angles and confirmation of the information from both angles assures product authenticity.
