Ear as a platform for latest biometric solution
Aakanksha Aakanksha, Himanshu Setia · 2011
Currently security has become one of the most widely researched areas and a lot of newer inventions are being added to it. This paper stresses on the use of ear biometrics for the same purpose based on the fact that ear is the least affected body part in terms of physical changes taking place in the body due to environment and natural growth. The concept of skin reflectance is made to work within the safe range of the EM wave spectrum following the fact that there is 54% reflection from the skin and 8% from the fats under the skin. An ear imaging mechanism has been suggested along with the proper detection of the reflected light using photometer. This is followed by the calibration of the reflected spectrum and then using the same spectrum to portray an ear uniquely. Codes and algorithms are depicted for the programming of spectrometer and setting the threshold value as per the maximum permissible error.
