Layered solutions combine overt, covert and/or forensic measures, multiple measures within identification classes and combinations thereof.  Periodic substitution of security measures achieves randomness and therefore further enhances anti-counterfeiting.

Typical layered solution examples include:

Color-Shift (Overt) + UV-Vis (Covert)
Microparticles (Overt) + IR Taggant (Covert)
UV-Vis (Covert) + DNA (Forensic)
