Ear biometrics as a means of identifying a double:
"...When employing face or lip as a biometric, changing of their appearance with the expression of the subject creates problem but in case of ear the shape and appearance is fixed.
...Identification by ear biometrics is promising because it is passive like face recognition, but instead of the difficulties to extract face biometrics, it uses robust and simply extracted biometrics like those in fingerprinting.

Rapiscan Secure 1000
Some have examined the technologies which the firm claims to have mastered in various fields of detection and believe that there may be hidden features which could be implemented in a Rapidscan Secure 1000 which might detect Aliens, Clones or Robotoid Synthetics. It is an avenue of research which at minimum should provide some interesting insight.
