CaeSaR Tags – Unclonable Patterns for Secure Authentication
A tag of bragg reflectors locked in a random arrangement provide a unique fingerprint for the marked objects
- A fundamental method for making the CSRs in a way that their optical performance is maximized and that scattering due to refractive index mismatch with the surrounding is avoided has been patented (pending).
- Applications are in progress for patents related to the read-out technology, recognition algorithms, methods for upscaling CSR production to industrial scale, and for realizing the rapid-solidifiable matrix material.
