Imagine this situation. After securing your personal information, including bank account details, the attackers are trying to transfer money to your account. To confirm the bank calls to specified phone number, but instead to 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, “investigating” the structure of a hearing aid – the attacker does not pass this test, and the bank receives a warning message about the data theft of his client.
Such a scenario is not fantastic – the technology of biometric user authentication on the structure of his hearing aid is quite viable. The fact is that even a person not only absorbs sound waves and reflects them in the opposite direction. Sensitive sensor that can detect small sound vibrations to perceive slight “echo”, to analyze incoming signal. The unique structure also provides a unique hearing aid reflected sound waves. How
demand technology can be said is that it can help to make quick identification of the individual in the case of calls to different call-centers, to secure banking transactions. In addition, having such a powerful tool for identification, it is possible to implement systems management bank account without having to enter a long identification numbers. The technology will also reduce the number of thefts of telephones – once configured to work with a particular user, mobile phones, will prohibit the calls in case of discrepancy of biometric data entered earlier.
technology is based on the phenomenon of otoacoustic emission, which is to spread the reflected sound waves in the human hearing system. The existence of this phenomenon was predicted as far back as the forties of last century, but to fix the reflected sound waves, researchers have been able only in the seventies with the advent of sufficiently sensitive microphones that can capture faint sounds. As a result of a number of studies have found that the reflected sound waves have a frequency of 0 to 5 kHz, and significantly different from each other in amplitude. But most importantly, the power and frequency characteristics of the signal can vary significantly, depending on the structure of Hearing individual.
Before researchers still face a number of unsolved problems, because even one person has changed their sound waves characteristics depending on a number of reasons, including when taking alcohol. Occur and certain age-related changes. Despite the difficulties, scientists still hope to find ways to circumvent them and finalize the draft by mid-2010, but then we can talk about the possibility of occurrence of the first mobile phones with the technology of sound biometry. The end point will be to develop software to work with sensitive microphones and the transfer of information obtained through the existing wireless networks.
