ABSTRACT:
A system and method for creating a unique optical signature that uses a plurality of optical signature chambers containing fluids having differing optical properties, for example differing indices of refraction, that produce different individual optical signatures for each chamber. If the chambers are broken causing the fluids to spill or the fluids are otherwise discharged from the chambers, the fluids mix together so one does not know which fluid came from which chamber, thereby preventing replication of the correct optical signatures. This destruction of the optical signatures can occur mechanically, without the application or presence of electrical power.
