International audienceSecure traceability is the ability to trace the lines of products a company releases on the market, while preventing attacks on the tracing system. This can be achieved by marking the objects with complex features, difficult to replicate for potential counterfeiters. Some of us have proposed to directly extract some signature from the structure of the material composing each product instead, as a vast portion of manufactured items on the market provide naturally random structures more difficult to replicate than man-made security markers. Having developed an industrial system for diffusing materials, we present here an optical setup that could achieve the same level of security for many different types of objects with specular surfaces
