Abstract
System and methods are described for irreversibly destroying optical signatures that utilize optical signature defining material, for example discrete objects or fluids, disposed in optical signature chambers to create individual optical signatures that together form an optical signature for the system. By irreversibly destroying the individual optical signatures, unauthorized replication of the system optical signature is prevented ensuring the security of the optical signature and any technology relying upon or tied to the optical signature.
