Risper- Construction - Software - Iris Recognition

The Panasonic BM-ET100 Authenticam

Iris recognition is cheap compared to most other systems. I still need to disassemble the device so the small video camera inside can be used as one of Risper's eyes. In reality the camera in the system is just an ordinary computer video camera. The main part of the system which does the recognising is the software. It is PrivateIDTM from iridian Technologies. The system doesn't keep a photo of your eye, but converts the pattern of the iris into a small code. The records are stored and compared to other iris codes for recognition. An iris code may look something like this

Average Capture Time Identifies user in less than 2 seconds Acquisition Distance 48cm - 54cm from camera lens for iris Imaging Self Alignment Interface Simple Multi-colour LED guides user to proper position Software Compatibility KnowWho / PrivateID architecture The idea will be for the robot to move its head until it has your eye in the right position for recognition. That will be less invasive for the person and they may not even know they are being identified. Remembering that identification is only needed so the robot knows who it is talking to.

Sharbat Gula around 12 years old

The pattern of the iris is complex and unique to each individual. Left vs. right eyes are different and eyes of identical twins also differ. Iris patterns show virtually no change over a person's lifetime. Although her name was not known at the time, Sharbat Gula's picture, titled "Afghan Girl", appeared on the June 1985 cover of National Geographic magazine. The image itself with her piercing green eyes staring directly into the camera was named as "the most recognized photograph" in the history of the magazine. Several attempts during the1990's to locate her was unsuccessful. A number of women came forward and identified themselves as the famous Afghan Girl. Her identity was confirmed using biometric technology which matched her iris patterns to those of the photograph with virtual certainty. She vividly recalled being photographed – she had never had her picture taken before or since. In the late 1980s, Gula married; she has three daughters. A fourth daughter died in infancy. Sharbat stated she hopes that her girls will get the education she was never able to complete. You can find a National Geographic article here and a Wikipedia article here.
