A new study – which compared the external ears of more than 1400 people of multiple nationalities, has found that the ear is as good an identifier of an individual as a fingerprint or DNA, and can even distinguish between identical twins..
"In this study, we demonstrated that the human ear may be a powerful tool to distinguish not only people in a random population but also genetically identical twins," Dr.
Balla said. "It may also mean that analysis of human ears could be used as an alternative to facial recognition systems.".
New ear identification technology up to 97.25% accurate
When you go to unlock your device using a biometric, it takes a live sample to compare it to the logs on the device, such as a picture of your face or in this case, a picture of your ear.Dec 8, 2022.
Fig. 1 User-specific characteristics are captured based on the shape of the ear canal by analyzing the acoustic reflection of the sound transmitted to the ear.
The basic principles of ear acoustic authentication can be explained with the air column resonance you learn in high school physics..
The physiological biometric features are the DNA, face, ear, facial, iris, fingerprint, hand geometry, hand vein, and palm print, with the behavioural biometrics being signatures, gait pattern, and keystrokes.
Voice is considered as a combination of biometric and physiological..
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..
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..
Ear biometric recognition is the study of automatic or semi-automatic methods for human identification or verification using 2D or 3D ear images..
Biometric modality: Ear – what is it? The shape and features of the human ear reveal specific characteristics that allow for the identification of an individual..
Ear features, which is a stable biometric approach that does not vary with age, have been used for many years in the forensic science of recognition.
The ear has all the properties that a biometric trait should have, i.e. uniqueness, permanence, universality and collectability..
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..
