Optical Lens Authentication Using Embedded Identifier Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for confirming the authenticity of optical articles, such as ophthalmic lenses, are susceptible to forgery, and existing systems lack robust verification mechanisms to ensure the product's genuineness and suitability for the wearer.
Innovation Solution
An authentication method and apparatus that utilize a unique identifier, such as a two-dimensional code or hologram, embedded in the lens, which is linked to a remote server database, allowing verification through a user terminal to confirm the lens's authenticity and provide additional product information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If paper certificates are used for authentication, then the authentication process is simple, but the certificates can be forged or applied to counterfeit articles
Solution Approach 1:
The patent replaces the mechanical paper-based certificate system with an electronic identification system using RFID tags or optical codes embedded in the optical article. This substitution eliminates the physical vulnerabilities of paper certificates while maintaining authentication functionality through electronic devices that can read and verify the embedded identifiers against a database.
Solution Approach 2:
The patent introduces a database as an intermediary between the identifier embedded in the optical article and the authentication process. The database stores reference identifiers and enables verification by comparing the embedded identifier against authentic records, thereby preventing forgery while maintaining a simple user-facing authentication process.
2Reliability
If an identifier system is implemented in the lens, then authenticity can be verified securely, but the device complexity increases
Solution Approach 1:
The patent embeds the identification system within the optical article itself by integrating RFID tags or optical codes directly into the lens structure. This nesting approach allows the authentication functionality to be contained within the product without requiring external authentication hardware, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The patent uses optical codes that can be captured and read as digital copies of the embedded identifier. This copying mechanism allows standard electronic devices with cameras or sensors to function as readers, avoiding the need for specialized expensive authentication equipment and thus limiting complexity increases.

AI summary
A method of checking authenticity of an optical article (L; F, L) including at least a lens (L), said method comprising the following steps: - acquiring an identifier carried by the lens (L); - sending, by an electronic device (10), a request containing the identifier to a remote server (20); - receiving, at the electronic device (10) and from the remote server (20), an information indicating retrieval of the identifier in a database (D); - displaying, on a display (15) of the electronic device (10), an indication of authenticity of the optical article (I; F, L). A corresponding apparatus, a method of providing a confirmation of authenticity of an optical article and a corresponding server are also described.
