This article proposes a super-resolution THz microscopy technique for biometric fingerprinting that images the stratum corneum surface layer of the finger as well as the epidermis and potentially even the dermis sublayers of the finger. The 500 GHz imaging frequency enables submillimeter resolution. The technique considers permittivity, conductivity and thickness of each layer of skin to interpret the spectrum response and distinguish between a spoof and a human fingerprint. THz fingerprint scans reveal features such as sweat ducts and variations in epidermis thickness that defeat spoofing attempts with a print on uniform materials such as epoxy, latex, glue or gelatin for a far more secure biometric fingerprint.
