Patent ID: 8098900

Claim:
A biometric device for detecting a presence of human skin rather than a gelatin-based candy used to mimic human skin, comprising: an illuminator source for providing a blue LED light source at a frequency of approximately 468 nanometers, wherein said blue LED light source is reflected from human skin; a photodiode detector for receiving said blue LED light source after said blue LED light source has contacted said human skin and for providing a signal representative of said blue LED light source after said blue LED light source is reflected from said human skin; a detector processing unit for comparing said signal with a known reflectivity value of human skin and a known reflectivity value of said gelatin-based candy used to mimic human skin, indicating said presence of said human skin if said signal matches said known reflectivity value of human skin, and positively determining said presence of said human skin prior to processing data collected from said biometric device; and a data processing unit that processes data collected from said human skin, wherein said data processing unit allows access to a controlled area or electronic equipment if said human skin indicates that an associated human is allowed access to said controlled area or said electronic equipment.
