Remembering too many passwords is no more a difficult task with the new form of biometrics. Fingerprints, Brain prints and now it’s time for the new biometric, which was developed by three scientists from the University of Stuttgart, Saarland University and the Max Plank Institute for informatics. The new biometric system that uses bone conduction of sound through the user’s skull in order to identify the individual by using devices, such as Google Glass or VR headsets is called Skullconduct.

With integration of Google glass smart glasses, scientists were successful in this test on few participants and the identification of individual was 97 percent accurate. Well, the process of SkullConduct uses the bone conduction speaker and microphone readily integrated into the eyewear computer and analyses the characteristic frequency response of an audio signal sent through the user’s skull.

“If recorded with a microphone, the changes in the audio signal reflect the specific characteristics of the user’s head,” the report published by Journal of the ACM states.

As the brain is unique, with slight structural differences and would be almost impossible to replicate, Skullconduct a prototype test developed Bone conduction is other method of receiving sound in a person which is used in this process of Skullconduct. When sound travels through the bones of the skull it is recognized for individual’s identification. This is not for the first time bone conduction technology is brought into the market. Since early 2000’s Headphones with feature of bone conduction are being sold. This technology played a crucial role in the raid that killed Osama bin Laden.

“Firstly, the prototype test Skullconduct was tested without any background noise, so making the system work effectively in an everyday environment will be the team’s next task. Secondly, the sound – some white noise – could also be annoying to users, and needs to be replaced with a short piece of music or a jingle,” the researchers added. Skullconduct is in its early stages and system has few serious works to be done before its sale. As it is initially tested in an environment without noise, it needs to be tested in such situations with noise to confirm whether it is helpful in areas like crowded internet cafes etc.

The conclusion of the researchers study says, “While other biometric systems require the user to enter information explicitly (e.g., place the finger on a fingerprint reader), our system does not require any explicit user input.” SkullConduct team will present the work at the Conference for Human-Computer Interaction in San Jose, California, in the month of May.
