Security starts with the physical O-KEY.
A tamper-evident, PUF-based O-KEY creates a unique physical reference that is registered and compared during authentication.
Security continues from the physical tag to verification
Create a unique physical reference
Random particle dispersion gives every PUF-based O-KEY unique physical characteristics.
Apply and register the O-KEY
Apply it tamper-evidently, then capture and register its physical reference.
Compare each authentication attempt
Use trained computer-vision models to compare each new capture with that reference.
Operate at the right threshold
Configure the comparison threshold to balance security and ease of use.
Product-level visibility to support action against unauthorized resale.
Seamless implementation gave us instant supply chain visibility.
What security and operations teams usually ask
What makes it hard to copy?
Each O-KEY has unique physical characteristics created by random particle dispersion. Authentication compares the presented mark with the registered reference, accurate to resolutions of 5µm.
What if someone tries to move the O-KEY?
Tamper-evident application helps reveal removal or transfer attempts. The right construction depends on the product, material and threat model.
Does this require chips or major retooling?
Not necessarily. O-KEY can be integrated as a label, seal, surface application or embedded format. We choose the lowest-change route that meets the security requirement.
Who should validate the security model?
Usually the function responsible for product risk, quality or safety, together with product and production teams. IT joins where systems or access are involved.
Start with the product you want to protect.
