hearing aids can store passwords of bank accounts   Imagine this situation. Get your personal data, including data on the bank account, an attacker trying to transfer money to your account. To confirm the bank is calling for the phone number, but rather than trust the words of the interlocutor, establishing his identity, the operator will have a much more interesting possibility. By pressing a special key is activated identification procedure using sound waves, exploring the structure of a hearing aid - the attacker does not pass such tests, and the bank receives a warning message about the theft of data of a client.
This scenario is not fantastichen - biometric identification technology on the structure of his hearing aid is quite viable. The point is that the person has not only absorbs sound waves and displays them in the opposite direction. Sensitive sensor that can capture small fluctuations in sound, able to perceive a weak echo, to analyze the signal came. The unique structure as a hearing aid provides a unique reflection of sound waves.
As far as demand may be the technology has already said that it can make a quick identification in case of calls to different call-centers, secure banking transactions. Besides, having such a powerful tool for identification, it is possible to implement systems of a bank account without having to input long identification numbers. The technology also would reduce the number of thefts of telephones - once configured to work with a specific user, mobile phones will be calls to ban the event of a discrepancy biometric data entered previously.
The technology is based on the phenomenon of otoakusticheskaya issue, which is reflected in the spread of sound waves in the human auditory apparatus. The existence of this phenomenon was predicted as far back as the forties of the last century, but the record reflected sound waves, researchers have been able only in the seventies, the advent of sufficiently sensitive microphones that can capture faint sound. As a result of a number of studies have found that the reflected sound waves have a frequency from 0 to 5 kilohertz, and vary considerably in amplitude. But most importantly, the power and frequency characteristics of the signal can vary widely, depending on the structure of a hearing aid a particular person.
Before researchers still face a number of challenges, because even a single human sound waves change their characteristics depending on a number of reasons, including to the reception of alcohol. There are some age-related changes. Despite the difficulties, scientists still expect to find a way to bypass and complete the draft by mid-2010, then the same can be said about the possibility of occurrence of the first mobile phones with sound technology of biometrics. The final point would be to develop software to work with sensitive microphones and the transfer of information through existing wireless networks.
