A certificate of authenticity (COA) is an inexpensive physical object that has a random unique structure with high cost of near-exact reproduction. An additional requirement is that the uniqueness of COA's random structure can be verified using an inexpensive device. Bauder was the first to propose COAs created as a randomized augmentation of a set of fibers into a transparent gluing material that randomly fixes once for all the position of the fibers within. In this paper, we propose a novel system for automated verification of fiber-based COAs and outline the key challenges in enabling high cost-efficiency of such a system. The key features of the new COA scanner are simplicity, reliability, lack of any moving components, and the ability to accurately identify exact positions of individual fibers infused in COA's containing paper. The latter feature significantly increases the forging cost compared to trivial implementations of a COA scanner.
