NEC develops biometrics technology that uses sound to distinguish individually unique ear cavity shape (NEC)
The new technology instantaneously measures (within approximately one second) acoustic characteristics determined by the shape of the ear, which is unique for each person, using an earphone with a built-in microphone to collect earphone-generated sounds as they resonate within ear cavities. This unique method for extracting features is useful for distinguishing individuals based on acoustic characteristics and enables rapid and highly accurate recognition (greater than 99% accuracy).
That doesn't sound like my signature (Press Release)
This partnership was formed to commercialize a Rolls-Royce developed signature verification technology called SignHear in several markets including healthcare, retail banking and child care security.
SignHear dynamic signature verification by Alaris is a biometric technology that verifies identity by analyzing the unique sound patterns created by an individual’s written signature. These sounds are captured and analyzed by a patented algorithm that generates an acoustic signature template unique to each user. The technology was originally developed by Rolls-Royce to run quality tests on jet engine blades. By firing a sound impulse into a blade and analyzing the resulting wave patterns, engineers were able to determine if any structural faults or anomalies were present.
