The sound reflected in the ear is used to identify the user

Realizing the echoes created by each ear canal structure are unique characteristics representing that person, Japanese scientists want to use this information as a security measure to identify users. So not only are the fingerprints, iris, the shape of the ear but now the echoes in the ears are also used as a biometric security measure, which enhances the level of safety for devices and information. or personal account, .

The project uses in-ear echoes as a security measure developed by NEC technology group and Nagaoka University, Japan. Researchers have found that the shape of each ear is unique so the echoes it produces are unique. They created a device that looked like a wireless inear headset, which contained both speakers and microphones.

The shape of each ear is unique so the echoes it produces are unique.

Normally, users will wear this device to listen to music, sound, . similar to other normal headphones. When you need to log in to a service or device, this device will emit special sound signals into the ear. These signals will move through the outer ear, ear canal, into the eardrum, middle ear and inner ear. The built-in microphone will capture reflected sound signals, then compare with the pre-recorded original information segment to identify the user. If matching, the wearer will be identified with 99% accuracy in just 2 seconds.

Researchers believe that feedback by sound feedback in this ear has many advantages over other measures. Most noticeable is that this approach is very simple and natural, all the users need to do is put on a headset and the biometric identification system will perform the whole process later through connection. cord. At the same time, this measure is considered to be safer because it is almost impossible to copy each ear's structure, especially this is not a hacker's knowledge. Finally, this method is convenient and fast, does not require physical interaction, the device is also quite compact.

The result of measuring the sound signal reflected from each ear is different.

The team collaborated with NEC Group to officially commercialize this security technology in 2018. Therefore, it is possible in the future, without keystrokes, without fingerprint scanning, retina scanning. And all we need is just a headset.
