Identification with a unique ear shape
The uniqueness of each human ear shape was very useful. In the future, the body that rarely noticed it believed could replace the role of fingerprints to identify a person's identity.
According to research at the University of Southampton, the shape of the ear on each individual is unique. Therefore, Prof. Mark Nixon who was involved in the study were also developing tools to recognize the uniqueness of these sensors.
In the future, sensors mounted face or retina at the airport will be replaced with sensors form ears. For all this time, a sensor to recognize faces and retinas have many shortcomings assessed.
Sensor face for example, will be even less accurate when the effects of aging begin to deliver the lines wrinkles on the face. In addition, these sensors can only recognize a neutral expression and difficult to recognize faces that are make-up.
Likewise, the sensors of the retina, in fact still have a weakness though is more accurate than the sensor face. The retina can only be identified from very close range, so that made it less practical for use in the centers of the crowd.
"The ear is more secure from the effects of aging and large enough to be recognized from a distance. Because the perfectly formed at birth, the ears did not experience any changes in a lifetime, "said Prof. Nixon was quoted as saying by the Telegraph, Sunday (10/10/2010).
Although only in the test phase, biometric sensor design Prof. Nixon has shown satisfactory results. We tried to identify the ear at 252, the resulting accuracy is 99 percent.
Trial results have also been in the percentage in the event the Fourth International Conference on Biometrics held recently.
