Abstract
A fiber optic bundle is placed through an object to be sealed. Ends of the fibers are spread and threaded through one another in a random dispersion, disorienting the fibers. Randomly reoriented ends are regathered and clamped. A moveable reticle at a light input termini of the fibers creates unique identifiable patterns at the output end of the fibers.
