Ear biometrics how it works

How does ear biometric work?
Ear acoustic authentication is a new biometric technology that identifies the shape of the ear canal using an earbud-type recognition device to measure reflected sound inside the ear..
How does ear shape biometrics work?
The ear, for example, has many distinct features, including the shape of the ear canal.
Ear acoustic authentication is a new biometric technology that identifies the shape of the ear canal using an earbud-type recognition device to measure reflected sound inside the ear..
By analysing a combination of features, such as the distance from the lobe to two points on the upper edge, it is possible to recognise someone from even a fuzzy picture of their ear with 99.6% accuracy in just 0.02 milliseconds.
Ear identification has been used for many years in countries such as France and details of an arrested person's ears were collected alongside face images and fingerprints as part of the criminal record.
External ear recognition
Modern biometrics technology can now capture and process ear features in the same way as other facial features.
Ear recognition has not yet been widely adopted but could be used for security purposes e.g. access to facilities and identity authentication in large enclosed spaces.
The advantages of this type of technology is that it can be used by persons wearing protective headwear, masks, gloves etc. and, as the ear canal is part of a hidden structure within the body, this helps to protect against presentation attacks ('spoofing') (Refer to the Biometrics Institute Good Practice Framework D.

Automatic person identification from ear images is an active field of research within the biometric community. Similar to other biometrics AbstractIntroductionMaterials and methodsExperiment results and

So, a contactless, non co-operative biometric system such as ear biometrics is the need of this hour. Most of the research works in the ear AbstractIntroductionMaterials and methodsExperiment results and

Is ear recognition a biometric?

Ear recognition is a kind of biometrics.
As a new biometrics, the theory and research of ear recognition arouse more attention of domestic and foreign scholars.
Traditionally, ear recognition can be segmented into two categories:

2D and 3D identification [ 2 ].
However, some verifications combine 2D with 3D image recently.

What are the advantages of 3D ear biometrics?

A range image is relatively insensitive to illuminations and contains surface shape information related to the anatomical structure, which makes it possible to develop a robust 3D ear biometrics.
The performance of 3D approaches for ear recognition is significantly higher than the 2D approaches.
