Eardentity
An Android ear identification app
Using the ear as a biometric Link to heading
Much of society strives to construct an unique and individual personality and some radically change their physical appearance so choosing a robust biometric to identify a human can be a challenge. Finger tips, iris, gait, face among others have been tried, tested and successfully rolled out - each with their own advantages and disadvantages.
In recent years the ear has emerged as a potentially useful biometric to suppliment existing solutions. Ears are more consistant than faces, do not change shape with different expressions or age and remain in a predictable position in the side of a head.
The relative positions of key parts of the ear such as the crus of the helix, the Tragus and the Concha can be used to form a reliable and robust identifier.
A small group of us decided to implement an Android app that can be used to identify people by their ears.

The app can auto-detect ears within a frame and can be trained from a single photo of an ear. This process can be described in the following three steps:
- We detect an ear using Haar-cascade
- We extract and describe ears using Local Binary Patterns (LBP)
- We identify ears using Chi-squared test
Managing Ears Link to heading
Ears can be stored and managed on the phone, ready to be identified for the future.
